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.

For any collection you create, Postman automatically generates machine-readable API documentation with sample requests, headers, and code snippets in various client languages. Customize your documentation to make it even more valuable to users.

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.

Verify if your APIs work as expected.

Check if your API continues to work as expected after introducing changes or updates.

Generate sample data that you can use to test your API extensively.

Test your requests with multiple values in a single run.

There are many ways to quickly share your Postman Collections with all your collaborators. Share via your workspaces, the Run in Postman button, or by providing a link. You choose whether to give new collaborators Viewer or Editor access to each collection.

Easily transfer collections from one workspace to another using the move feature. Moving collections helps you collaborate effectively, especially while working with your team. This is great for users that want to add their collections to a team workspace or make them available via their organization's Private API Network.

Create a new instance of your collection seconds by forking it. With forking, you can use a collection's requests or suggest changes without affecting the original. This is helpful if you want to keep the current collection version untouched while working in parallel on new API features. If you'd like to incorporate your changes into the original collection, you can easily merge your fork into the parent element.
