Comprehensive API Testing
Because Postman is so easy to use, your entire team can collaborate on testing—including your non-technical project managers, business analysts, and others—to make sure everything works just the way it's supposed to.
To give you maximum flexibility in your testing, Postman supports a wide range of API standards, specs, and formats, including REST, SOAP, GraphQL, OpenAPI, RAML, Swagger, JSON, cURL, WADL, and more.
Run thorough, end-to-end API tests
Make sure your API does exactly what it's supposed to do.
Make sure your API can handle stress and perform at expected levels.
Make sure your API handles unexpected input and behavior.
Make sure your API delivers reliable responses across geographic regions.
Make sure your API continues to perform after code changes with regression testing.
Troubleshoot, debug, and fix
Send requests and examine responses
Send requests and examine API responses directly within Postman to find fixes quickly.
Understand exactly what's happening
Use the Postman console to dig deep and inspect every network call, including headers, certificates, requests, and responses. You can even use the console to log messages.
Collaborate with your team
Run comprehensive test suites
Create test suites that can run again and again—from simpler functional tests to comprehensive, end-to-end tests and full regression testing.
Import many different schema formats including cURL, RAML, Swagger, WADL, JSON, OpenAPI, and GraphQL.
Use code snippets
Use Postman code snippets to run tests against APIs without writing code.
Write tests faster
As you type Postman will prompt you with suggestions—simply select a suggestion to autocomplete your code.
Organize multiple elements like tests, monitors, and mocks around your APIs, or use Postman collections, workspaces, and folders.
Send individual requests—or all the requests
Send individual requests or run every request in a collection using the Postman Collection Runner.
Collaborate and share
Collaborate and share APIs and collections with team members using Postman workspaces.
Run collections of requests
Use Postman's Collection Runner to run collections of requests in specific sequences, log test results, and pass data between requests—or even pass data files into a run. Collection runs allow you to automate your API testing, and you can schedule runs using monitors.
Automate testing and more with Newman
Use Newman, the command-line Collection Runner for Postman, to run and test Postman Collections directly from the command line. It's built with extensibility in mind so that you can easily integrate it with continuous integration servers and build systems.
Monitor API responses
API monitoring allows you to schedule and automate monitors across regions in the cloud or in your pipeline. You can review your API responses, availability, and performance with each run to ensure that your API is always healthy.
