📄Core Concept

How Do You Handle API Pagination in Postman?

Key Takeaways & Architecture Summary

✓Assert total page metadata returning inside response headers or payloads.
✓Write loop logic using postman.setNextRequest() to query sequential pages.
✓Validate that pagination indices successfully offset record counts.

Direct Answer Summary

To handle and test API pagination in Postman, you extract pagination metadata (e.g. `next_page_url` or `total_pages`) from the response payload. You then use `postman.setNextRequest()` in the Tests tab to loop and call the next page until a target condition or page limit is reached.

⚠️ Senior Engineering Warning (Red Flag)

Never write infinite pagination loops without a break limit. If the API has hundreds of pages, your test will loop endlessly, consuming server resources and crashing your test runner.

💡 STAR Architectural Explanation & Pro Tip

`postman.setNextRequest()` overrides the default sequential execution order of the Collection Runner, enabling custom looping and conditional branching during automated runs.

// Postman Tests: Loop pagination until last page is reached
const data = pm.response.json();

if (data.page < data.total_pages) {
    pm.environment.set("nextPage", data.page + 1);
    postman.setNextRequest("Fetch Users List"); // Loops back to the same request
} else {
    postman.setNextRequest(null); // Terminates the collection runner loop
}
