The screen show below shows the Swagger editor for our sample database API. You can also generate API clients for a wide range of programming languages Swift, Kotlin, Go, Android, CSharp, PHP, Java, Javascript, Typescript - just to mention a few. This opens a new window with your API documentation.įurthermore, if you click the Open link to the Swagger editor, you can view/edit the API specification. To generate a complete API documentation for the database, click the Open link. The screen shot below show how this looks for our sample database.
The securityDefinitions and security keywords are used to describe the authentication methods used in your API.Swagger is a set of open-source tools built around the OpenAPI Specification that can help you design, build, document and consume REST APIs. For example, this JSON object:Īnd then referenced in the request body schema and response body schema as follows: They can be referenced via $refwhenever a schema is required – both for request body and response body. The global definitions section lets you define common data structures used in your API. not a number).ĭescription: A user with the specified ID was not found. You can also provide example responses for different content types.ĭescription: The ID of the user to return.ĭescription: The specified user ID is invalid (e.g. Schemas can be defined inline or referenced from an external definition via $ref. You can define the parameter types, format, whether they are required or optional, and other details:ĭescription: Parameter description in Markdown.įor each operation, you can define possible status codes, such as 200 OK or 404 Not Found, and schema of the response body. Operations can have parameters that can be passed via URL path ( /users/), query string ( /users?role=admin), headers ( X-CustomHeader: Value) and request body. For example, GET /users can be described as: The paths section defines individual endpoints (paths) in your API, and the HTTP methods (operations) supported by these endpoints. The root-level definition can be overridden in individual operations. The consumes and produces sections define the MIME types supported by the API. The base URL for all API calls is defined using schemes, host and basePath:Īll API paths are relative to the base URL.

info also supports other fields for contact information, license and other details. description can be multiline and supports GitHub Flavored Markdown for rich text representation. You can use (as in semantic versioning), or an arbitrary format like 1.0-beta or 2016.11.15. Then, you need to specify the API info – title, description (optional), version (API version, not file revision or Swagger version). A Swagger version defines the overall structure of an API specification – what you can document and how you document it. A sample Swagger specification written in YAML looks like:ĭescription: API description in Markdown.ĭescription: Optional extended description in Markdown.Įvery Swagger specification starts with the Swagger version, 2.0 being the latest version. In this guide, we only use YAML examples, but JSON works equally well. The available versions are 3.0.0, 3.0.1, 3.0.2, and 3.0.3 they are functionally the same. OpenAPI 3.0 uses semantic versioning with a three-part version number.
Swagger definitions can be written in JSON or YAML. The OpenAPI version defines the overall structure of an API definition what you can document and how you document it. To learn about the latest version, visit OpenAPI 3 pages. OAS 2 This page applies to OpenAPI Specification ver.
