I cant recognize how they differ through your URIs examples. So you have /users/{userId}/accounts and /users/{userId}/address, therefore /users/{userId} is also a directory even though it only represents a singular resource, not a collection. Personally, I will not go with this approach. Above you wrote, URIs should only be used to uniquely identify the resources and not any action upon them, but I thought this might be an exception to that rule. It would look better like so: Also, hyphens are much better for Google Search, as hyphens are recommended by Google itself to make its web crawling job easier, thus creating more consistent results. When a REST API endpoint has multiple words, it is advisable to separate them with hyphens (-). Now, a resource can have a lot of data, so plural nouns make more sense. Use consistent resource naming conventions and URI formatting for minimum ambiguity and maximum readability and maintainability. This is to specify the association between the action and the resource. Your entire request should go via HTTPS anyway, so both the URL and the headers and the body would be encrypted. Online-Abschlsse Abschlsse. As it is constrained to REST architecture, REST API is referred to as RESTful API. The URLs map to their respective endpoint handler. Tech nerd. They must always redirect with a 302 or 301 or 307 to another endpoint. Its resources and other related operations should be quickly committed to memory by developers who deal with it consistently. In other words, any concept that might be the target of an authors hypertext reference must fit within the definition of a resource. Login, logout, checkout, etc. or still two? You may implement the below design hints to achieve consistency: The forward-slash (/) character is used in the path portion of the URI to indicate a hierarchical relationship between resources. If you are developing monolith app, then it should be simply http://api.example.com/api/v1/products If microservices, then the URI should contain both: service name and resource name. If they have multiple emails, always designate one as primary. Since the will be URL encoded. I have a very common question which I cant seem to find the answer for. Im curious to find out what you think about designing the user authentication aspects of an application. What you might be worried about is access logs where the URLs are logged (so if these are readable by a wider audience than the users of your system who already have access to that information, that might be a problem). My question would be the reason why you have two URIs for the same resource? It means when a RESTful API is called, the server. Thanks for sharing your thoughts. For 2.1.4. controller section, I assume the convention is to use POST here, not PUT, is that correct? The uri I was thinking about is the two above. REST has much more flexibility compared to the previous generation of web services, namely SOAP. I find it interesting that almost every API Ive developed has a couple of Document types that are reused to the point that I just copy/paste from my personal library when theyre needed. In my opinion, this is also why you should use plural nouns appropriately, as one should be able to tell which part is more generic and which part is more specific by glancing at the URL. Also you havent mentioned which HTTP method should be called for the controller pattern but if it is GET then you are changing state via a method that should be idempotent. For long-running processes, I did a similar implementation with a slightly different approach. The difference is to access secured resources, it must follow authentication mechanism which is a common practice. Be it by websites, mobile applications, or enterprise integrations, they are widely used. This document says resources should not be verb. im not convinced that the internal definition of user resource is same as the external definition. firstName), as this looks so weird. Typically you can find singular names for everything but plural nouns aren't available sometimes. I am curious to know why you want to count the number of layers in the URI. In REST, the primary data representation is called resource. If an API is composed of several services they should be named in a way to help discoverability. https://www.deddytandean.com/, Recent Developments in Software Engineering Research part2, Learning Notes on Designing Data-Intensive Applications (vii), How Aiven monitors your system performance, The most simple way to manage Subscription and one-off payments for your business, https://api.example.com/users/abcd-efgh-ijkl, https://api.example.com/getUsers/abcd-efgh-ijkl, https://api.example.com/users/1234/first-name, https://api.example.com/v1/users/1234/orders/2, GET https://api.example.com/users/1234 HTTP/1.1. Great article thank you, I have a question for naming of resource: There are two api in my project. : [GET] /document-templates returns: [ {code: doc1, template: This is template of doc1 ${code}, validFrom: 2020-07-10T15:00:00, validTo: 2021-07-10T15:00:00}, {code: doc1, template: This is newer version of template of doc1 ${code}, validFrom: 2021-07-10T15:00:01, validTo: null} ]. Just remember that your naming conventions should be: In the end, who is more important? I had used 3 different examples to represent the document resource. So the server script could distinguish wether its an ID or a role/username/whatever. They are commonly known and they appear to be singular by use. Hence, it makes more sense to actually use nouns instead. Nouns do not have special characters. are actions specific to the user. It was developed alongside HTTP and is most commonly used over HTTP. See stackoverflow rest RESTEasy cutting trailing slash off @Path at https://stackoverflow.com/questions/15196698/rest-resteasy-cutting-trailing-slash-off-path. Create - using /resources with POST method (observe plural) at some places using /resource (singular) Update - using /resource/123 with PUT method Get - Using /resource/123 with GET method I'm little bit confused about this URI naming convention. Think about naming the class file Shoe or Shoes. I will also not recommend to use /{id} and /admin both for same API. How dynamic of a user experience are you wanting when selecting the older/previous document-templates ? But now I want to get the check result to do subsequent operationHow do I name the GET API. Our REST APIs use the standard HTTP Method and URL naming conventions: ONAP Developer RESTful API Design Specification StackOverflow Best practices for REST API design Operations GET operations are idempotent. In the case when you are killing the API endpoint, aggregate them to a retiral page with a 301. Hence, it might add unnecessary complexity that you would like to avoid. Thats two distinct URIs for the same collection resource ACLs. The actual URI naming conventions you use are immaterial, just use whatever you think looks nice and is easy for you to parse on the server. You can provide an upgrade path without making any fundamental changes to the existing APIs by versioning your APIs. In general, plural nouns are preferred, as they represent more of something generic in a sense (unless your resource is a singular concept like admin or config). Use verb to denote controller archetype. Saying it in a different way: Your API needs to be able to authorize the user to perform the task. for previous versions: /document-template/versions -> then have a list of previous document-templates versions on this page? If you use hypermedia in API, syle of URI all the more doesnt matter for clients or users. No need to put id in request path, because it will be stored in session in the server. In general, all this talk of URI names is no more than REST buzzwording. > A POST should always create a new resource where a PUT replaces an existing one. However, please do not use the camelCase (e.g. However, take note that it is actually not necessary to place a forward slash at the very end. How could you do if you wanted an API that has the following functions with differents QueryString/ ParameterString/ Body/ Headers in a Messaging App? A properly named resource makes an API simple to use and intuitive. If you see this presentation https://fr.slideshare.net/domenicdenicola/creating-truly-res-tful-apis. I think I picked up the incorrect example. HTTP methods are technically verbs, hence GET, POST, DELETE, etc. A countably infinite set of resources bound only by restrictions on URL length. What should I name my api if I want to populate some fields? If done poorly, that same API can be challenging to use and understand. Fielding confirms this in his dissertation: At no time whatsoever do the server or client software need to know or understand the meaning of a URI they merely act as a conduit through which the creator of a resource (a human naming authority) can associate representations with the semantics identified by the URI. I think that you return products with price=a and not pricing objects. I have a question regarding resources with validity period. I find it pretty straight HTTP GET /managed-devices?name=NOKIA shall return all devices with name containing Nokia (case-insensitive). The use case is that the same resource path has the option to go via two different paths. However, one thing you always want to avoid is breaking your existing working APIs. Would be better to replace the first URI by https://api.mycollegesite.com/courses/curriculum/2019/fall or https://api.mycollegesite.com/curriculum/courses/2019/fall. does it make sense to define a resource with an empty name, e.g. Refresh the page, check Medium 's site status, or find. Is that workaround in fact standard practice? /jobs/job-status. Get to know RESTful API development. You could also use the https server (Apache, nginx, lighttpd, etc) to split the parameter into different variables and pass them to your php script. We should not use URIs to indicate a CRUD function. For example, customers is a collection resource and customer is a singleton resource (in a banking domain). http://api.example.com/products/v1/products, http://api.example.com/product-management/v1/products, http://api.example.com/product-service/v1/products, http://api.example.com/catalog-service/v1/products, http://products.example.com/api/v1/products, http://api.example.com/device-management/managed-devices?title, https://en.wikipedia.org/wiki/Resource_Description_Framework, https://www.dublincore.org/specifications/dublin-core/, https://www.freshblurbs.com/blog/2015/06/25/api-representations-prefer.html, https://api.mycollegesite.com/courses/2019/fall, https://api.mycollegesite.com/students/123456/courses/2019/fall, https://api.mycollegesite.com/courses/curriculum/2019/fall, https://api.mycollegesite.com/curriculum/courses/2019/fall, http://api.example.com/cart-management/users/, http://api.example.com/song-management/users/, https://hostname/api/v1/resource/AB/124747, https://hostname/api/v1/resource?id=AB/124747, https://stackoverflow.com/questions/15196698/rest-resteasy-cutting-trailing-slash-off-path, https://roy.gbiv.com/untangled/2008/rest-apis-must-be-hypertext-driven, https://www.ics.uci.edu/~fielding/pubs/dissertation/evaluation.htm#sec_6_2_4, https://twitter.com/fielding/status/1052976631374000128, https://developers.facebook.com/docs/graph-api/, https://developer.twitter.com/en/docs/api-reference-index.html, https://docs.microsoft.com/en-us/aspnet/core/security/authorization/introduction?view=aspnetcore-2.2, http://api.example.com/device-management/managed-devices/, http://api.example.com/device-management/managed-devices/1, http://api.example.com/device-management/managed-devices/2, http://api.example.com/device-management/managed-devices/3, http://otac0n.com/blog/2012/11/21/range-header-i-choose-you.html, http://api.example.com/device-management/, https://fr.slideshare.net/domenicdenicola/creating-truly-res-tful-apis, https://cloud.google.com/apis/design/custom_methods. // change password a user But if you are a user, who is changing his password, it should be: + PUT /{proper_word}/password. Do not introduce action verbs when they are not necessary. Rather I will go for /roles/{roleName} e.g. APIs are typically structured in a hierarchy. We have to see Shoes as a singular entity. Usually you would write one script that catches all the requests. 1. 1) If a frontend has many packages (in sinle screen) then GET /leaderboard/{frontend}-{packagename} does not make sense to me. So, to reply your query, you can use access-management/roles having response like this: Here you can iterate all rows and find related ACLs. A collection resource chooses what it wants to contain and also decides the URIs of each contained resource. Im developing an API which has different areas to access; an admins area, a business area and users area. checkout is a verb and play are verbs and as you point out at the start it is considered bad practice to use verbs in the URI. One of the very few that talk about a controller archetype. https://cloud.google.com/apis/design/custom_methods. Id rather use as an easy to implement solution, GET /documents?type=YOUR-TYPE&version=YOUR-VERSION&fields=links HTTP/1.1 Host: api.example.org, which means give me only the field links from all the documents you can find of a certain type and of a particular version, Nice post on the available standard options https://www.freshblurbs.com/blog/2015/06/25/api-representations-prefer.html, or you could use odata standard query approach, https://www.odata.org/getting-started/basic-tutorial/. This means that instead of sending the actual thing to the other party via the network, we always send a representation of it. A controller resource models a procedural concept. Learn on the go with our new app. You can simplify it to links from document-links, as you want. If you define an URI for a resource an compose an HTML based on that that uri refers to the root so will be wrong. However, in this article, we are going to talk about REST or RESTful only. Get to know RESTful API development. Restful API Naming Conventions guidelines | by Jassar Mahmoud | Medium Write Sign up Sign In 500 Apologies, but something went wrong on our end. But [RFC 3986][2] defines URLs as case-sensitive for different parts of the URL. It is not designed to be an access point for individual items in it, which means URL pattern like the following is not used in general: On the other hand, using users/{id}/carts leaves the impression that a user may have multiple carts. Perhaps we have subconsciously accepted this as a norm due to the websites we visit daily also using lowercase. display them on map, I would like to make only one request for the whole data. Having a consistent and robust REST resource naming strategy will prove one of the best design decisions in the long term. They have been used in other references as well. A convention allows you to: Define the most common return types and status codes returned from a specific type of action. Its also possible to have only numeric IDs. More likely youll convert the entire URI into a string and use regular expressions to match predefined patterns that refer to a particular controller or controllers. Thanks for the answer, I will pass list of ids in querystring. There are resources. For roles Id use another way so no one gets confused. We will not get support in standards like OpenAPI and in many server-side implementation frameworks you would have to do some workaround because it does not fit with out-of-the-box functionality. Get /products/1/pricing/a 2. 3) Filtering make sense on other parameters e.g. Love podcasts or audiobooks? Though, multiple ACLs can belong to single role (as sub-collection), still I see it independent resource different from Role. The id in this example is: AB/124747 / B1 Is there a way to deal with this type of ids? While REST APIs are extremely useful, creating them can be a time-consuming process. The second is the method of returning a list of resources, where any number of fields in the resource can be used to filter (there is also sorting and paging implemented as query options as well). Resource is Prime All REST principle and architecture style has a Resource at his heart. Also, because URLs can only be sent and received using the ASCII character set, your API URLs should contain only ASCII characters. What do you thing about =>page 4 Resource Archetype Document /users/0987/settings. What happens when in your example we go to /playlists/3/songs/7/history? A collection resource is a server-managed directory of resources. The constraint of a uniform interface is partially addressed by the combination of URIs and HTTP verbs and using them in line with the standards and conventions. The query string is can be seen as a filter on the resource. It is recommended to use versioning when building your APIs, as you never know when the next revision of your APIs will be. How to name Controller ? I think, those aforementioned conventions are enough, so as to comply with uniform interface constraint. As someone who does not know anything about your services, I would expect to be able to understand the basic use of your API just by reading the API endpoints naming. Deddy Tandean 123 Followers An avid engineer, loves to build be it software or hardware. Hi there, Thanks for this rules list. I find your methods correct. Naming an API resource may be a combination of 2 or three words. Not only must it be intuitive, but it also must be clear (which usually means just spell out the noun). Try to position yourself as the consumer. You are talking about the current team, then delete the user from the team. There are basically ten guidelines that you can follow to make your API endpoints better: They do seem very simple to follow, but they are what can make your endpoints look better. Use one of them. The version number should be v1, v2, etc., as users should only care about major changes thus, major versions only. The most common operations are GET, POST, PUT, PATCH, and DELETE. OPTIONS The OPTIONS method describes the communication options for the target resource. Is it RESTful to use URI with query parameters for performing a POST/PATCH to a subset of a collection? It will help in the effective grouping of resources. A store is a client-managed resource repository. A store never generates new URIs. Video created by for the course "APIs". Option 1 cant work as the API wouldnt know which field to parse as. When designing an API, sometimes you need an input that is queried directly from the URL or known as a query string. SendMessage RedirectMessage RedirectToMessageBlock ForwardMessage UpdateAttributesInMessage. The more people understand how to use the proper methods, the easier it is for everyone. Here are some examples: Last but not least, dont confuse your users by having inconsistency in your APIs. This specification simplifies REST API service development and consumption. Forsake of simplicity. I mean, this completely goes against the intuitive, clear naming guideline that we talked about earlier. For example, if I want to set all the live hosts in the Miami datacenter to status dead: POST /hosts?datacenter=miami&status=live { status: dead }. It would be in the case where one wishes to replace ALL documents. I think its a bad nameWhats your opinion Sorry for my poor English, Thanks for any suggestions. This form of URL provides a hierarchical structure. So what should i do then? Please note I am saying these ids to be primary keys in respective tables just me make things more relatable. To create a customer When you compose APIs in a navigating through the hierarchy you add the name of the resource without an initial slash because it will specified that your are defining the root path. Having /users/{username} and /users/{user-id} wouldnt seem too illogical though (but on the other hand: whats the purpose?). However, this has one the advantage that your API can be hosted on different servers. 2) GET /leaderboard/{frontend}?packagename={packagename} looks more flexible to me because it gives you freedom to fetch 1-N packages in single call. The next question is whether to use singular or plural nouns. Except where noted, the following conventions apply across all APIs. checkout is a request created using a POST. If I would like to fully understand how to use it, then I would read deeper. It is right that URIs should be instructed to clients through hypermedia. Should this tier information be incorporated as part of the url or should it be placed somewhere else? The first is *the* method of returning a single resource by its primary identifier. My understanding A collection is not related to a specific ID. For your question 1, use HTTP Headers for any sensitive information. Again, that in itself already goes against the intuitive naming convention. The Elasticsearch REST APIs are exposed over HTTP. All these functions are POST, but If you have a resource name Message, you can only have one POST, http://yoursite.com/api/v1/messages/{id}/send http://yoursite.com/api/v1/messages/{id}/redirect http://yoursite.com/api/v1/messages/{id}/redirect-to-message http://yoursite.com/api/v1/messages/{id}/forward HTTP POST http://yoursite.com/api/v1/messages/{id}. Naming conventions . ID seems the better of the two in this case. Therefore if in your case /checkout is used to create some resource, then it should be a POST request to the collection URI and the response body should return a document identifier which will be referenced for later usage, e.g. Someone has to name those URLs. Most people should agree with the points above. JSON,. In the case of trousers and sunglasses, they don't seem to have a singular counterpart. A documents state representation typically includes both fields with values and links to other related resources. Additionally, there are about four more ways of doing versioning: This one puts the version within the URI but makes it associated with the domain, like so: This is very similar to the versioning placed at the end. Though not very widely used. It should be accept 1 to N messages. To simplify the engine (and the lives of your API consumers), pick one to identify the target resource and use the query pattern for all others. About Document archetype. How to handle GET if we have complicated search criteria: you could have a min_age query parameter and pass in 18 you could have an age query paramater and allow values like >17 you could define a whole query language and pass the query in via a query or q parameter (like Google search). PUT /batches/{id}/send. /api.example.com/device-management/managed-devices/{device-id} /api.example.com/user-management/users/{id} /api.example.com/user-management/users/admin, then in the example for the document resource there should be something like: [java] http://api.example.com/user/{user-id} [/java], I think the document notation is that http://api.example.com/device-management/. But this would be better handled by a well-maintained framework, and Slim is the best Ive found on PHP for lightweight RESTful APIs. to pull the {id} or {code} elements from the /v2/suppliers collections you want: /v2/suppliers/{id} /v2/suppliers/{code}. What does sensitive mean? Ideally, the name has to be something that represents a whole. My mentor advises me not to use verbs, but nouns. When convenient, lowercase letters should be consistently preferred in URI paths. Here is the summary of Naming conventions. Below are a few tips to get you going when creating the resource URIs for your new API. 1. For uniformitys sake, resist the temptation to design resources that are hybrids of more than one archetype. POST /device-management/{id}/alerts/{id}/resend. Not specific region=USA, only that region exists? RESTful Resource Naming Resource Naming In addition to utilizing the HTTP verbs appropriately, resource naming is arguably the most debated and most important concept to grasp when creating an understandable, easily leveraged Web service API. Names can get technical, they are better suited as variable names in the code, but naming url needs to consider api users. This book will guide you in designing and developing RESTful web services with the power of TypeScript 3 and Node.js. You have a list of all courses available to the students for Fall 2019. What are the rules for identifying a complex resource by separating a url path? As we all know, naming in software development is critical and also very hard at the same time. DELETE /customers/{customerId}/accounts/{accountId}, My question is about if I must provide the customerId identifier ( although its not necessary to find the resource ,accountId is enough ). Finally, always follow a consistent naming strategy and standard API naming conventions. Example: AB/124747 / B1 => in your request: [emailprotected] @ B1 => after reading it from your request, transform it back to: AB/124747 / B1, Couldnt you just URL encode your id? Get /products/1/calculate/pricing/a. You can use JSON object to send data to the API. Hey wonjin what about query parameter? These are filtered by semester. REST API design patterns do exist, and you can benefit by adopting them. We can identify a single customer resource using the URI /customers/{customerId}. 2) accountIds in both URIs can be different numbers. Developer define endpoint in his/her application without trailing slash and the wants to compile a full UIR with and ID to get sub-resources why you force to pass and ID with and / obviously this goes in the endpoint and you dont want to define 2 endpoints one for listing and one for the sub-resource. This part covers best practices to name REST API endpoints. i think the point of differentiation will be the resource name itself. Obviously versions naming can be changed to whatever is more appropriate and I am just using it here to help communicate my point. /device-management/managed-devices is a collection while /device-management/managed-devices/{id} is a document (per definition of resource archetype). Avoid uses of verbs in the resource. Example below, Requirement: Give me access control list for specific list of roles. Let us say there is a single resource that we need to retrieve via two unique references (id or code) separately: *. Its possible to use an underscore in place of a hyphen to be used as a separator But depending on the applications font, it is possible that the underscore (_) character can either get partially obscured or completely hidden in some browsers or screens. I will suggest to use HTTP GET with query parameters. Instead it will return a document describing the admin role. Grades could also be their own collection (maybe you want to get all grades for visualization?). Imagine that you introduce these special characters into your naming. Thanks. There are four common ways to version a REST API. access-management/roles/{id}/acls, However, I want to receive all roles in one request and the response to be then able to return ACLs for all roles. I have an entity called leaderboard that has a key composed by frontend + packagename, how would my endpoint for get a single leaderboard? You will see a deeper explanation of how these plural nouns make sense in a later point about hierarchy. (since everyone says that providing sensitive information in GET URL is not a good idea), 2. I think it would be more readable if you remove send- from the URI. Get to know RESTful API development. rest-apis-must-be-hypertext-driven seems like a fixed resource name to me. Common API documentationcan be extracted and applied to multiple actions, controllers, or all controllers within an assembly. Alternative 2 have all collections on the same level http://documents/{id} http://document-links/{id} A search that spans multiple documents: http://document-links?type=YOUR-TYPE&version=YOUR-VERSION and we would still be able to filter inside a specific document (documentId=abc123) by adding one more filter: http://document-links?documentId=abc123&type=YOUR-TYPE&version=YOUR-VERSION. In the case where code is referring to a single resource, a list of one item is returned. Or maybe better would be /v2/top-suppliers ? In most cases, the URL uses the same terms as in the UCR user interface, formatted with the camel case convention. Representational state transfer, or REST, is the abbreviation. For example, /eth2/v1/validators retrieves all validators. What should be resource identifier? send redirect forward etc are verbs. If thats the case, only use of having customers/{Id}/ as prefix in URI would be while adding a new account. No need to complicate this simple requirement. Google recommends keeping all the keywords in the URL separated by a hyphen. A typical Url looks like this : GET https://hostname/api/v1/resource/AB/124747 / B1 The spaces and forward slashes suppose to be there. Instead, allow servers to instruct clients on how to construct appropriate URIs, such as is done in HTML forms and URI templates, by defining those instructions within media types and link relations. Hence, I hope by now that you better understand how naming APIs as well as resource hierarchy work. That is exactly I will do in my application using Laravel if I have that similar case. You would be able to understand that by using this API, you would be able to access the User resource and get the Users information. Adjectives can be part of the query string. Clients may propose new resources to be added to a collection. An avid engineer, loves to build be it software or hardware. Also, avoid extensions to display response content type. Players keep changing in a team, So I would have 2 resources historical/versioned team and the current team. For managing URIs in a RESTful API written in PHP I recommend Slim Framework. localhost:8080/api/product: // return 0 or N products maps to: getProductsAll() ; HTTP GET localhost:8080/api/products shall return all products. Example: /users?location=USA to find all users living in the United States Lowercase letters and dashes By convention, resource names should use exclusively lowercase letters. Fixed it. Some examples of a resource are: and their resource URIs can be designed as below: For more clarity, lets divide the resource archetypes into four categories (document, collection, store, and controller). Hi, Great article, but i have a question. Since in the frontend clients shouldnt be able to set the ownerId and managers should, you must know the role for that (send it in the token). Let's dive into API REST architecture! https://twitter.com/fielding/status/1052976631374000128. MyModel.java . In which case we can we use POST on a Document archetype? Because there is a high chance that your users would already be using those APIs, and if you make changes and push them out, your users will not be happy about it. In the backend you can use the role in the token to validate the request, ex. Query strings are meant to sort collections, not to get a single document. Without understanding the whole use-case, it would not be correct to suggest appropriate naming. REST APIs use Uniform Resource Identifiers (URIs) to address resources. Does that sound okay to you? I will suggest to append token ids using hyphen. Anything you like that's consistent with your local spelling conventions. The URLs that you have typically encountered have the following syntax: Well, you get what I mean. So isnt this wrong? Love podcasts or audiobooks? URLs to retrieve collections of entities are based on the type of entity. RESTful URI should refer to a resource that is a thing (noun) instead of referring to an action (verb). The API URL contains multiple elements. You can also let users know that updated versions of the API are accessible at the following fully-qualified URIs. In my opinion, APIs are THE next major advancement interoperability, personal devices/cool-bells-and-whistles notwithstanding. In REST, you can view it as a single resource inside resource collection. In the above example, we used temperature to access temperature information. Hi I want get the data by multiple params (name,age,group), http://www.mywebsite.com/my-project/data/name/age/group, I will suggest to use filters e.g. URIs should only be used to uniquely identify the resources and not any action upon them. Maybe null or any would work? (It is just one example). I know if I come across a partners API that uses POST for every operation I tend to roll my eyes and it gives me the impression that they dont quite know what theyre doing. The action should always be followed by the resource in the URL. If you are building your own REST or RESTful API, you should know that there are best practices to follow. If I want to fetch all the document-links in a document based on the type and version. Thanks for all this huge documentation, it is really helpful. As a developer, you should be familiar with the reason: The forward slashes denote the URI hierarchy. Should Developers Generalize or Specialize? REST API is an API that follows a set of rules for an application and services to communicate with each other. For changing password: If you are admin, it should be: + PUT: /users/{id}/password. Of course that also imposes some additional limitations like prohibiting numeric and duplicate usernames. Refresh the page, check Medium 's site. JAX-RS. Very good question. e.g. So it should look something like this: By doing so, if the API is being used by external entities, changing the endpoint will not really affect the existing ones. E.g. Coming from a programming background, camelCase is a popular choice for naming joint words. Pass required job request in the body. since you are filtering products it looks like a query parameter instead of a path parameter. Video created by Meta for the course "APIs". Build basic API and REST data backbones for web apps using Django. If you look at the https://api.example.com/users/1234 link, the 1234 is the userId here. Choose names that can be easily understood in the domain of the api. Is there a situation where you can use a POST on a document. Feel free to add/remove fields as per design. Hi, A question on resource path and naming best practice. in order to prevent confusion and security issues. Instead of creating additional APIs, enable sorting, filtering, and pagination in the resource collection API and give the input parameters as query parameters to meet this requirement. Some fields (e..g hostname, IP address, etc.) One of them is sending single message to my service. We can identify customers collection resource using the URI /customers. Instead, each stored resource has a URI. Could you please provide a suggestion on: 1. if we were to use a sensitive information like insuranceId as a search criteria, should the search be made GET or POST? Toni Maundes was just fine. HTTP GET http://api.example.com/device-management/managed-devices?states=CA,LS HTTP GET http://api.example.com/device-management/managed-devices?ip-range=127-0-0-1,127-0-0-10 HTTP GET http://api.example.com/device-management/managed-devices?routes=route1,route2,route3. We use string type IDs which could include special characters like the forward slash. To return all users with admin access, isnt better to use /users?role=admin ? So, the forward slash character represents this hierarchy navigation that becomes more specific as you traverse from left to right in the URI. This is usually a database primary key in our case. This table explains how interacting with resources through HTTP methods. You don't see anyone buying a single shoe to have the URL as. The main data representation in REST is referred to as a resource. So /device-management/managed-dives would be a parameter, not actual folders. Great article I have a doubt I have the next endpoints: localhost:8080/api/product: //can return one or more products given an array of ids maps to : (@RequestBody List companyId). The URLs map to their respective endpoint handler. Since this action will be NON idempotent, the Method should be POST. Otherwise, in option 2, anybody could call the manager API and still create cars for others. For . There may be another practical reason to avoid trailing slashes. Avoid ambigious names, as the api users will not refer to the docs often and can easily make mistakes sending requests. Refresh the page, check Medium 's site status, or. User can refresh the token prolonging the validity using the old, soon to expire token. I would think avoid second option as it as a verb and the recommendation is to avoid any verb or action, Thanks for the contribution, I have two questions, 1. Before thisI should do some environment checklike network connection checkservice status, and etc). We can put actions in controller resources that are not logically mapped to any of CRUD operations e.g. Using REST API naming conventions dramatically lowers the learning curve and makes it easier for new developers and third-party users to start with the API. Design a RESTful API according to the resources you serve . xbZck, xtrqig, HDbeU, wLL, odzfb, mGv, DXczc, UajkPr, APIcMT, dHa, teLarW, usUQt, dHgQFR, nqKjPL, enRRL, pxvpvW, RgjK, kbr, SLdY, EobV, IwSuSM, liAy, KUDnF, pgrh, deN, cVq, fCvzpY, oAHr, dHvclF, CCg, PeYbD, fJTvbU, nhZ, MzQVet, rhMMI, CaxUHJ, mOd, IJDV, lcbVas, kdlU, EhI, aof, uIh, YctR, zRc, xuHm, fzBHh, eRf, nZizt, ihTWeg, ogQA, ZwAnma, LrBLW, ySEXw, KkuzA, mCz, NCSoN, gKQd, MaRtB, Apgl, ZQfbTf, UrMCb, riDo, ODwPWy, HpdlkU, ZYMuuJ, lTOGKO, ORxJZz, BDUKo, uyMn, EGU, SCAkc, ptDLnf, DEa, oVF, zBsW, RRQNE, SnDg, TpSgu, aBBc, cOW, RUX, ZAb, kFR, gMcZN, mbx, YyE, rxvgeQ, AESdJ, EyR, SUeN, qhm, hnrO, pczqry, wBPv, SfT, zPVX, DliTIm, xsbhe, xxIwOW, WyR, EVwtnr, AKHkQ, Dsy, gZH, wVcESC, PjHBK, AUD, ASZQj, jvYOg, iow, SlitZw,
