API Testing with Postman

Test, automate, and document APIs efficiently using Postman. This hands-on course covers the full API testing workflow from writing and scripting requests to automating test runs and integrating with version control, so you can deliver reliable, well-tested APIs with confidence.

What You'll Learn

By the end of this course, you will be able to:

• Write and execute API requests across REST, SOAP, GraphQL, and HTTP protocols
• Script and automate tests using Postman's built-in testing and scripting tools
• Generate dynamic data and parameterize requests for flexible, reusable test cases
• Organize and document tests in collections for team collaboration and review
• Automate test execution using the Collection Runner, Postman Monitors, and Newman
• Integrate API workflows with GitHub for version-controlled API development
