What is API testing via Postman? Postman is the most widely used API platform for building, sending, and validating API requests, letting teams test REST and SOAP services, check status codes and response data, and automate entire test suites without heavy coding. For QA and engineering teams, it is one of the fastest ways to confirm that APIs behave correctly, securely, and reliably before a release reaches production.
As applications depend on more interconnected APIs and release cycles shorten, this program helps your teams automate API testing with Postman and catch breaking changes before they reach users. Empower your people with expert-led on-site, off-site, and virtual sessions delivered by Edstellar, a premier corporate training provider serving organizations worldwide. Built around your goals, the program turns Postman skills into lasting capabilities that lift quality across QA, automation, and development teams.
Delivered instructor-led and fully customized to your APIs and tech stack, the training is available worldwide in person and virtually across popular languages, and covers Postman end to end, from collections and authentication to scripting, mock servers, Newman CLI execution, and CI/CD integration. Your organization gains faster, more reliable releases, less manual regression effort, and engineers who can build maintainable API test suites with confidence.

Participants should be comfortable with basic software testing concepts and understand how web APIs, HTTP methods, and JSON work. Familiarity with REST APIs and a little scripting is helpful but not required, as the program includes guided setup and hands-on labs. Edstellar tailors the starting point to your team's experience, so both testers new to API automation and engineers extending existing Postman suites can take part productively.
