API Testing Fundamentals with Agent Mode
Build a Postman collection and turn it into a real test suite — all through Postman's Agent Mode. In this first module you'll create the workspace and collection you'll test, then prompt Agent Mode to write your first assertions: the status line, the response headers, and the shape and values of the response body. Let Agent Mode do the typing, but never approve a test you can't explain. You'll practice against the Movies API, a free, public REST API with no authentication.
Advanced API Testing with Agent Mode
Take your Movies API test suite beyond the happy path — all through Postman's Agent Mode. This module is fully self-contained: it recreates the workspace and collection from scratch (with a baseline of status, header, and body tests), then goes deeper — negative tests for missing resources and invalid input, workflow tests that chain requests with variables, a response-time budget, and finally running the whole suite with the Collection Runner and auditing your own coverage. Let Agent Mode do the typing, but never approve a test you can't explain. You'll practice against the Movies API, a free, public REST API with no authentication.
API Monitoring
Your tests only protect you when they run. In this module you'll build a small health-check collection, wire it to a Postman Monitor, and let Postman run it from the cloud on a schedule — so you find out your API is broken before your users do. You'll schedule runs, attach an environment, tune advanced settings, turn on failure alerts, then trigger a run and read the results.
Data Files in Postman
Run one collection dozens of times with different inputs — without duplicating requests. In this module you'll parameterize a Movies API request with {{movieId}} and {{expectedTitle}}, drive iterations from a CSV or JSON data file in the Collection Runner, then attach the same file to a Monitor and prove the cloud run executed every row. Data files are a Solo+ feature; you'll need a paid Postman plan to complete the monitor steps.
You'll practice against the Movies API, a free public REST API with no authentication. When your testing outgrows fixed files, the follow-up module covers datasets — reusable, unlimited test data that also works in CI.
Get Started with Performance Testing
Learn to spot when an API buckles under traffic — then prove it with Postman’s Performance runner. You’ll build a small coffee API collection, practice reading avg vs p95 in a safe load lab, run a Fixed App test, and set a pass/fail bar you can reuse from the CLI. You'll need the Postman desktop app for the App run. Practice against the free Sample APIs coffee endpoints. Local App runs work on every plan.
