How to Add Descriptions to Collections in Postman

You open a Postman collection someone else built three months ago. No descriptions. No context. Just a wall of requests with cryptic names like getUserData_v2_FINAL_fixed.

Sound familiar?

Here’s the hard truth: 63% of developers say poor documentation is their biggest productivity killer. And Postman collections without descriptions are one of the most common — and most fixable — documentation gaps teams live with every day.

The good news? Adding descriptions to your Postman collections takes less than two minutes. It saves hours of back-and-forth, speeds up onboarding, and makes your API workflows actually usable by the whole team.

This guide walks you through exactly how to do it — step by step, at every level of your collection.

Why Descriptions in Postman Collections Actually Matter

Before jumping into the how, let’s talk about why this is worth your time.

Postman now has over 30 million users across 500,000+ companies worldwide. That’s a massive number of teams sharing collections, collaborating on APIs, and onboarding new people into existing workflows every single day.

The data behind documentation quality is hard to ignore:

• 83% of developers say API documentation quality directly influences whether they use an API or not
• Teams with well-documented APIs reduce developer onboarding time by up to 50%
• APIs now drive $2.2 trillion in annual economic value globally — and clarity of documentation is one of the top drivers of adoption
• A Postman State of the API report found that improved documentation is consistently ranked as the top request from API consumers

A collection description isn’t just a nice-to-have. It’s the difference between a teammate spending 10 minutes understanding your setup versus spending two hours debugging your intent.

How to Add a Description to a Collection

This is the most important place to start. Your collection-level description sets the context for everything inside it.

Step 1 — Open Postman and locate your collection

In the left sidebar, find the collection you want to document. Click the three-dot menu (•••) next to the collection name.

Step 2 — Click “Edit”

From the dropdown, select Edit. This opens the collection editor panel on the right side of your screen.

Step 3 — Navigate to the “Documentation” tab

Inside the editor, you’ll see tabs across the top: Authorization, Pre-request Script, Tests, Variables, and Documentation. Click Documentation.

Step 4 — Write your description

You’ll see a text editor field. Postman supports Markdown formatting here, so you can use headers, bold text, bullet lists, code blocks, and even links.

A strong collection description typically covers:

• What this collection does and what API it covers
• Who it’s for (which team or use case)
• Authentication setup required
• Any environment variables that need to be configured
• Known limitations or versioning notes

Step 5 — Save your changes

Click Save in the top right. Your description is now live and visible to anyone who opens the collection.

Pro tip: Postman renders your Markdown in the published documentation view. This means clean formatting now pays off later when you share the collection externally.

How to Add Descriptions to Folders Within a Collection

Most collections contain folders that group related requests together. Each folder can — and should — have its own description.

Step 1 — Hover over the folder name

In your collection’s left sidebar, hover over any folder. You’ll see the three-dot menu (•••) appear to the right of the folder name.

Step 2 — Click “Edit”

Select Edit from the dropdown. A modal window will pop up.

Step 3 — Add your description in the text field

The modal includes a description field below the folder name. Use this to explain:

• What requests this folder contains
• The logical flow or sequence of requests (if order matters)
• Any folder-specific variables or dependencies

Step 4 — Save

Click Save and your folder description is added.

This one step alone can prevent the most common frustration on shared teams: someone running requests in the wrong order and wondering why everything breaks.

How to Add Descriptions to Individual Requests

Request-level descriptions give context at the most granular level. They’re especially valuable for complex endpoints or requests with many parameters.

Step 1 — Open the request

Click on any request inside your collection to open it in the main panel.

Step 2 — Click on the request name or the description field

Just below the request name at the top, you’ll see a small greyed-out text that says “Add a description…”. Click directly on that text.

Step 3 — Write your description

Again, Markdown is supported. For request descriptions, consider including:

• What this endpoint does
• Required headers or parameters explained in plain language
• Sample response structure
• Common error codes and what they mean
• Rate limits if applicable

Step 4 — Save

Click the Save button (or use Cmd+S / Ctrl+S) to save the request and its description.

Best Practices for Writing Postman Collection Descriptions

Writing the description is one thing. Writing a useful description is another.

Be specific about inputs and outputs. Vague descriptions like “gets user data” are almost as unhelpful as no description at all. Instead: “Returns the authenticated user’s profile including name, email, subscription tier, and last login timestamp.”

Document the unexpected. The most valuable descriptions explain what isn’t obvious — quirky behavior, deprecated parameters still in use, or endpoints that require a specific call sequence.

Use Markdown intentionally. Headers break long descriptions into scannable sections. Code blocks make example payloads immediately readable. Bold text highlights warnings. Use all of it.

Keep it current. Stale documentation is dangerous. When you update a request, update its description in the same commit or sprint. Treat it like code — if it’s wrong, it’s a bug.

Write for the next person, not yourself. You already know how this works. Your documentation is for the developer who joins six months from now at 9pm on a Friday before a deadline.

in Postman Descriptions — A Quick Reference

Since Markdown is supported throughout Postman’s description fields, here’s a quick cheat sheet:

Postman renders Markdown both inside the app and in your published API documentation — which means well-formatted descriptions translate directly into professional external documentation without extra effort.

How to Publish Your Collection Documentation

Once your descriptions are in place, Postman lets you publish the entire collection as a public-facing documentation page.

Step 1 — Click the three-dot menu on your collection

Select View Documentation from the dropdown.

Step 2 — Click “Publish”

In the documentation view, you’ll see a Publish button in the top right corner.

Step 3 — Configure your published page

Choose your environment (so variable values are visible), set the URL slug, and decide whether the page is public or private.

Step 4 — Share the link

Postman generates a hosted URL for your documentation. Share it with your team, clients, or embed it in your internal wiki.

Companies that publish documented collections report significantly faster API integration times from external partners. Teams using shared Postman documentation reduce API integration questions by up to 40% — fewer Slack threads, fewer meetings, more shipping.

Conclusion

Adding descriptions to Postman collections is one of the highest-leverage documentation habits you can build. It costs minutes. It saves hours. And across a team or over the lifetime of a product, it prevents the kind of confusion that quietly slows everyone down.

Start with your most-used collection today. Add a two-paragraph description at the collection level, a one-liner for each folder, and a clear explanation for your top five most complex requests. That’s it.

The next person who opens that collection — including future you — will thank you for it.
