Creating and Organizing Collections

Collections are at the heart of organizing and streamlining your API testing and development workflow in Postman. They serve as containers for grouping related API requests, allowing you to efficiently manage, execute, and collaborate on various endpoints and scenarios. In this section, we’ll delve into the concept of collections in Postman, guide you through the process of creating and organizing them, and offer valuable tips for maintaining a structured and well-documented API testing environment.

Understanding Collections in Postman

What is a Collection?

In Postman, a collection is a logical grouping of API requests. Think of it as a dedicated folder that holds a set of interconnected requests. Collections provide a means of structuring and organizing your API tests, making it easier to manage, execute, and collaborate on specific use cases.

The Role of Collections

Collections in Postman offer numerous advantages:

  1. Organization: Collections help maintain order in your API testing and development workspaces. They allow you to categorize and structure requests, ensuring quick and efficient access when needed.
  2. Efficiency: Collections enable you to run multiple requests at once, streamlining the testing process and saving valuable time.
  3. Collaboration: Collections can be shared with team members, making it easy to work on API testing and development as a group.
  4. Automation: Collections can be integrated into automated test scripts, making it possible to schedule and run tests automatically.

Creating and Organizing Collections

Let’s take a closer look at how to create and organize collections in Postman:

Step 1: Launch Postman

  1. Open Postman on your computer.
  2. If you haven’t created a Postman account yet, you’ll be prompted to do so. An account isn’t mandatory, but it offers additional features and collaboration options.

Step 2: Navigating the Postman Workspace

  1. After launching Postman, explore the user interface. You’ll find the left sidebar, which contains options like “Collections,” “Environments,” “APIs,” and more.
  2. For now, focus on the “Collections” tab.

Step 3: Create a New Collection

  1. Click on the “Collections” tab in the left sidebar.
  2. Hit the “New Collection” button to initiate the creation of a new collection.
  3. Provide a name for your collection, and consider adding a brief description for context.
  4. Click “Create” to finalize the creation of your collection.

Step 4: Organizing Requests Within Collections

Once you’ve created a collection, you can begin adding requests to it:

Step 1: Select Your Collection

  1. From the left sidebar under “Collections,” click on the collection you wish to populate with requests.

Step 2: Create a New Request

  1. With your collection selected, use the “Add Request” button to craft a new API request.
  2. Specify a name for the request and pick the request type (e.g., GET, POST, PUT, DELETE).
  3. Enter the request URL and configure any headers, parameters, or other settings as necessary.
  4. Select “Save” to incorporate the request into your collection.

Step 3: Executing Multiple Requests

  1. Collections offer the remarkable capability of running multiple requests in a single action.
  2. To run all the requests in a collection, locate and activate the “Run” button in the collection view.

Step 4: Sharing and Collaborating

  1. Collections can be conveniently shared with your collaborators or team members.
  2. Click on the “Share” button for your collection to generate a shareable link. Your colleagues can then import the collection into their Postman workspace.

Best Practices for Collection Organization

Maintaining a structured and well-documented collection is crucial for seamless API testing and development. Here are some tips to consider:

  • Descriptive Names: Give your collections meaningful, descriptive names. This ensures clarity when selecting the right collection for a specific task.
  • Categorize Requests: Group related requests within a collection. For example, you can create collections for user management, product catalog, or payment processing.
  • Subcollections: Utilize subcollections to further structure and organize your requests, providing an additional layer of hierarchy.
  • Documentation: Add comments or descriptions to your requests to provide context and clarity. Documenting requests aids in understanding their purpose and functionality.
  • Regular Maintenance: Periodically review and update your collections to ensure they remain relevant and organized. Remove redundant or obsolete requests.

By following these best practices, you’ll be able to maintain a tidy and effective collection of API requests, making your testing and development work in Postman both efficient and organized.


Collections are a fundamental element of Postman that simplifies the management, execution, and collaboration of API requests. With collections, you can categorize and structure your API tests efficiently, collaborate effectively with your team, and seamlessly automate testing processes. As you continue your journey with Postman, mastering the use of collections will prove to be a valuable asset in your toolkit.
