Mastering Folder Structure in Postman: A Beginner’s Guide

1 Introduction

As a back-end developer, organizing folder structures in Postman has proven to be an invaluable skill. This technique not only boosts my efficiency but also ensures seamless collaboration with front-end developers during endpoint testing and integration. This article,serves as a detailed guide for beginners, using a generic "TunaresQ" example to demonstrate how to create a professional folder structure in Postman, complete with practical endpoints.

2 Why Folder Structure Matters

A well-organized folder structure in Postman is crucial for successful API testing and collaboration. It allows developers to group related endpoints, making navigation, testing, and maintenance simpler. For a project with multiple modules—such as user management, payments, and product categories—a clear structure saves time and reduces confusion during development and testing phases.

3 Example Project Layout

Consider a generic project named "TunaresQ." This project can be subdivided into several sub-folders, each representing a specific module or functionality. Below is the proposed folder structure based on typical development tasks:

• TunaresQ

4. Setting Up Your Folder Structure in Postman

Follow these steps to replicate the folder structure in Postman, as shown in the screenshot:

1. Create the Main Collection
   
   Open Postman, click "New" > "Collection", and name it "TunaresQ."

2. Add Sub-Folders
   
   Right-click the "TunaresQ" collection and create the following folders:

• Commons

  • Industries
    • POST Create Industries: Add new industry data.
    • PUT Update Industries: Modify existing industry records.
    • GET List Industries: Fetch a list of all industries.
  • Startup Stages
  • Team Sizes
  • Payment Types
  • Payment Methods
  • Payment Methods Configuration
  • Payments Details

• Auth & User Management

• Waitlist

• Fundraiser Category

• Fundraisers

• Individual Details

• Startup Details

1. Add Endpoints
   
   Inside each folder, create HTTP requests for the relevant endpoints. Use naming conventions like POST, PUT, and GET to indicate the method, followed by the endpoint purpose.

2. Organize and Test:
   
   Ensure endpoints are placed in the correct folders and test them thoroughly. Collaborate with your team to identify and resolve any issues early in the process.

Best Practices for Beginners

• Clear Naming: Use descriptive names like “POST Create Products” to indicate the HTTP method and purpose.

• Logical Grouping: Keep related endpoints together (e.g., all payment-related requests under “Payment Methods”).

• Team Collaboration: Share the Postman collection with your team via a link or export to ensure everyone uses the same structure.

• Documentation: Add notes in Postman (e.g., under each request) to explain what each endpoint does, making it easier for beginners to understand.

Benefits of This Approach

By adopting this folder structure, you’ll notice improved workflow efficiency. Front-end developers can quickly locate the endpoints they need to test, while back-end developers can easily update or debug them. This organization also prepares you for scaling the project as new features, like additional payment types or user management tools, are added.

Conclusion

Creating a folder structure in Postman is a foundational skill for any developer, especially when working on collaborative projects. By following the structure outlined above with the “TunaresQ” example and adding endpoints thoughtfully, beginners can build confidence in testing APIs professionally. Start small, experiment with the endpoints, and refine your approach as you grow—happy coding!
