Postman is a popular tool for working with APIs. It’s user-friendly and has a cool feature called Collections. In this article, we will talk about what Collections are and how they help you organize and manage your API requests efficiently.
Prerequisites
We will discuss the following two approaches to organize requests in Postman Collections:
Postman Collections are a very useful feature of Postman that simplifies containers or folders which helps to organize and structure your API requests. Instead of dealing with individual requests, Collections allows you to group related requests.
Benefits of Postman Collections
- Organization: By using the collections we can organize requests, which makes it easier to navigate and understand the API structure.
- Reusability: All the requests within collections can be reused across different scenarios, which increases efficiency.
- Collaboration: Collections can be shared among team members so that they can use the same set of requests for testing.
Let suppose you are working on an e-commerce API that includes various endpoints for user authentication, product management, and order processing. Instead of having a list of requests, you can create separate Collections for each of these categories.
This way, all requests related to user authentication can be grouped within a “User Authentication” Collection, making it easy to locate and manage them.
Example:
Requests:
- Login
- Logout
- Refresh Token

Approach 2: Sequencing Requests:
Collections define the order in which requests will be executed. This is particularly useful when your API calls need to be performed in a specific sequence.
For instance, you might have a sequence of requests for user registration, login, and profile retrieval. By organizing these requests into a Collection, you ensure that they are executed in the correct order.
Example:
Collection Name: User Registration
Requests:
- Register User
- Login User
- Get User Profile
