Data Types
Multiples Use the multipleOf keyword to specify that a number must be the multiple of another number: type: integer multipleOf: 10 The example above matches 10, 20, 30, 0, -10, -20, and so on. multipleOf may be used with floating-point numbers, but in practice this can be unreliable due to the limited precision or floating point math. type: number multipleOf: 2.5 The value of multipleOf must be a
Adding Examples | Swagger
OAS 3 This guide is for OpenAPI 3.0. If you use OpenAPI 2.0, see our OpenAPI 2.0 guide. You can add examples to parameters, properties and objects to make OpenAPI specification of your web service clearer. Examples can be read by tools and libraries that process your API in some way. For example, an API mocking tool can use sample values to generate mock requests. You can specify examples for obje
Inheritance and Polymorphism
Model Composition In your API, you may have model schemas that share common properties. Instead of describing these properties for each schema repeatedly, you can describe the schemas as a composition of the common property set and schema-specific properties. In OpenAPI version 3, you do this with the allOf keyword: components: schemas: BasicErrorModel: type: object required: - message - code prop

OAS 2 This page applies to OpenAPI Specification ver. 2 (fka Swagger). To learn about the latest version, visit OpenAPI 3 pages. In Swagger, API operation parameters are defined under the parameters section in the operation definition. Each parameter has name, value type (for primitive value parameters) or schema (for request body), and optional description. Here is an example: paths: /users/{user

OAS 2 This page applies to OpenAPI Specification ver. 2 (fka Swagger). To learn about the latest version, visit OpenAPI 3 pages. An API specification can include examples for: response MIME types, schemas (data models), individual properties in schemas. Examples can be used by tools and libraries, for instance, Swagger UI auto-populates request bodies based on input schema examples, and some API m
oneOf, anyOf, allOf, not
OpenAPI 3.0 provides several keywords which you can use to combine schemas. You can use these keywords to create a complex schema, or validate a value against multiple criteria. oneOf – validates the value against exactly one of the subschemas allOf – validates the value against all the subschemas anyOf – validates the value against any (one or more) of the subschemas Besides these, there is a not
Authentication
OAS 3 This guide is for OpenAPI 3.0. If you use OpenAPI 2.0, see our OpenAPI 2.0 guide. Authentication and Authorization OpenAPI uses the term security scheme for authentication and authorization schemes. OpenAPI 3.0 lets you describe APIs protected using the following security schemes: HTTP authentication schemes (they use the Authorization header): Basic Bearer other HTTP schemes as defined by R
Bearer Authentication
Bearer authentication (also called token authentication) is an HTTP authentication scheme that involves security tokens called bearer tokens. The name “Bearer authentication” can be understood as “give access to the bearer of this token.” The bearer token is a cryptic string, usually generated by the server in response to a login request. The client must send this token in the Authorization header

Introducing the Open API Initiative!
I'm thrilled to announce the next chapter in the journey of Swagger. Today we are announcing a partnership with some of the biggest names in the API space to create an open governance model around the Swagger Specification under the Linux Foundation. This secures Swagger as the basis for describing REST APIs, and will help it's adoption accelerate faster than ever. Why does this matter? As more co
REST API Documentation Tool | Swagger UI
Swagger UI Swagger UI allows anyone — be it your development team or your end consumers — to visualize and interact with the API’s resources without having any of the implementation logic in place. It’s automatically generated from your OpenAPI (formerly known as Swagger) Specification, with the visual documentation making it easy for back end implementation and client side consumption.

REDOC – AN OPENAPI-POWERED DOCUMENTATION UI
We all love SwaggerUI. It is one of the reasons Swagger/OpenAPI is so popular. Recently a few new trends have appeared in API documentation world. One of them is three-panel design documentation. The competing API specifications formats have them, e.g. API Blueprint has aglio, Postman has Postman Documenter, etc. That's why APIs.guru has been developing new reinvented OpenAPI-powered documentation
The New Swagger Editor and UI Are Finally Here!
The Swagger framework changed the software landscape forever, allowing APIs to be described in a common language (the OpenAPI Specification) that every human and machine involved in the lifecycle can understand, work and integrate with. While the specification is the core of the framework, there is an entire toolchain around it to enhance the API development process. The most popular and fundament

Using $ref
When you document an API, it is common to have some features which you use across several of API resources. In that case, you can create a snippet for such elements in order to use them multiple times when you need it. With OpenAPI 3.0, you can reference a definition hosted on any location. It can be the same server, or another one – for example, GitHub, SwaggerHub, and so on. To reference a defin

Describing Parameters
OAS 3 This page is about OpenAPI 3.0. If you use OpenAPI 2.0, see our OpenAPI 2.0 guide. In OpenAPI 3.0, parameters are defined in the parameters section of an operation or path. To describe a parameter, you specify its name, location (in), data type (defined by either schema or content) and other attributes, such as description or required. Here is an example: paths: /users/{userId}: get: summary
