Define your APIs

Define the structure of your API by creating a new schema or importing a schema

  • Create

    Design new API schemas in Postman to make API creation faster

  • Import

    Import existing API schemas in popular schema formats (Open API 1.0/2.0/3.0, RAML 0.8/1.0, GraphQL)

  • Generate

    Generate collections automatically based on your API schema

  • Sync

    Bi-directionally sync your API schema on Postman with your GitHub repository

  • Validate

    Validate your API elements against your API schema

API Design Example in Postman.

Supported Schema Formats



Postman supports the latest OpenAPI specification as well as Swagger 1.0/2.0.



The RESTful API Modeling Language (RAML) has become a popular choice for designing APIs.



Postman allows you to author and send GraphQL queries using the request body.

Develop your APIs

Streamline the entire API workflow around the API itself

  • Test Integrations

    Add integration tests to check if your endpoints work as expected with other APIs and services

  • Test Contracts

    Write contract tests to ensure that your APIs are working according to their specification

Learn more about continuous testing of APIs

Observe your APIs

Monitor, report, and analyze how your APIs are performing

  • Monitor

    Connect monitors in your workspaces with APIs.

  • Report

    Collect and review API reports under a single view in the Postman web dashboard.

  • Analyze
