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.
