Postman API design
Postman brings design, testing, documentation, and monitoring into a single workspace, so developers can move fast and teams can enforce standards with built-in governance.
Define your APIs
Define the contract of your API by creating a new specification or importing existing ones using Spec Hub
Create
Design new API specifications in OpenAPI 3.0 or AsyncAPI 2.0 formats, streamlining API creation
Import
Import existing API specifications in popular formats (Open API 1.0/2.0/3.0, RAML 0.8/1.0, GraphQL)
Generate
Automatically generate collections from your API schemas and specifications, with types in collections enabled for detailed request definitions
Sync
Maintain bi-directional synchronization between your API specifications in Spec Hub and your GitHub repository, ensuring consistency across development environments
Validate
Validate your API elements against your API schema
Supported schema formats
OpenAPI
Postman supports the latest OpenAPI specification as well as Swagger 1.0/2.0.
RAML
The RESTful API Modeling Language (RAML) has become a popular choice for designing APIs.
GraphQL
Postman allows you to author and send GraphQL queries using the request body.
Develop your APIs
Generate comprehensive API documentation directly from your schemas and API collections, ensuring accuracy and consistency.
Mock servers
Create mock servers to kick start development faster.
Documentation
Write API documentation or generate it from schema
Environment
Store variables for all your different development environment
Sharing
Share your APIs with other members of your team
Test your APIs
Add test suites, integration tests, and contract tests to your APIs
Test suites
Link collections, enriched with types, in your workspace as test suites to an API using version tagging
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
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
Understand API performance, collection executions, test failures and team-level metrics.
