What is a Postman collection?
A Postman collection is like a digital folder for organizing API requests. It helps streamline API development and testing by grouping related requests. For example, imagine you are working on a project that involves multiple APIs. In your Postman collection, you can create folders for each API and include specific requests.
This allows you to easily access and test different API endpoints as you work on your project. Overall, a Postman collection simplifies API management by providing a structured approach to organizing and executing requests.
Creating a Postman collection
Launch Postman
Launch the application to get started once you have Postman installed and are logged in.
Create a new collection
Click on the New button in the Postman interface’s top left corner. From the dropdown menu, select Collection and give it an appropriate name that reflects its purpose.
Adding requests to the collection
- Manual Method: To add requests manually, click on the collection you just created and then click the Add Request button. Provide a descriptive name for the request and enter the details, such as the URL, HTTP method, headers, parameters, and body.
- Import Method: Postman supports various formats for importing requests. You can import existing requests in cURL, Swagger, RAML, or other compatible formats by clicking the Import button. Locate the file and follow the prompts to import the requests.
Organizing requests
- Folders: To enhance the organization of your requests, create folders within your collection. Click the dotted icon on the right side of the Collection Name and select Add Folder. Name the folder something meaningful and drag and drop relevant recommendations into it.
- Request order: You can easily arrange the order of requests within a collection or folder by dragging and dropping them to the desired position. This ensures that the requests are executed in the intended sequence.
Managing a Postman collection
Running a collection
If you want to run all the requests within a collection, click on the collection name and then click the Run button. Postman will execute all the requests in the specified order, making it convenient for testing or automated workflows.
Collection runner
The Collection Runner is a powerful feature that allows you to run collections with multiple iterations and different data sets. This is especially useful for testing different scenarios or running performance tests. You can configure variables, pre-request scripts, and test scripts to customize the execution of your collection.
Sharing a collection
Postman provides various options for sharing your collections with team members or collaborators. Click the “…” button next to the collection name and select the Share button to create a public link to share your collection or invite specific individuals via email. This facilitates seamless collaboration and knowledge sharing.
Documentation
- Postman allows you to generate interactive API documentation from your collection. Documentation provides valuable insights into the available endpoints, request/response details, and usage examples.
- To generate documentation, click the “…” button next to the collection name and select View Documentation. From there, you can access the documentation and share it with others.
