Collections

Define and send API requests, retrieve data from a data source, and test API functionality. You don't need to enter commands in a terminal or write any code. Simply create a new request and select Send, and then the API response appears right inside Postman.

Postman automatically generates machine-readable documentation from your collections—now enriched with reusable data models using types in collections. These types bring clarity and consistency to your request and response documentation, including parameters, headers, and body schemas.

Variables enable you to store and reuse your values in Postman, helping you work more efficiently and making your requests more readable. Variable scopes in Postman relate to the different contexts that your requests run in, allowing you to tailor your processing to any development, testing, or collaboration tasks.

Pass authorization details along with any request you send in Postman. Postman automatically populates the relevant parts of the request for your chosen auth type. Use variables and Collections to define authorization details more safely and efficiently.

Debug APIs quickly and easily by adding tests to your requests and examining responses. Postman also allows you to reuse your test suites to create a CI/CD pipeline, so you can test at every push. Integrate your Postman instance with Travis or Jenkins to create your own CI/CD pipeline or add it to your existing pipeline as a build step.

Add pre-request scripts to define the commonly used pre-processing or debugging steps you need to execute for multiple requests. Whether you add your pre-requests to your entire Collection or a folder within your Collection, your pre-request script will run before every request in the Collection or direct child request in the folder.
