What is API Tester?

API Tester is a software application used by developers and testers to test application programming interfaces (APIs). It provides an interface for constructing API requests, sending them to target servers, and inspecting the responses.

Key features of API Tester include:

  • Building requests by selecting HTTP method, entering URL, adding headers, parameters, and body payloads
  • Sending requests and viewing response status, headers, cookies, and returned content
  • Testing APIs by validating response codes, content, performance metrics, and integration
  • Repeating requests while modifying parts of it to test different scenarios
  • Exporting request collections to share with other developers and team members
  • Offering multiple environments for targeting local, dev, test, and production API endpoints
  • Tracking history of sent requests during a test session
  • Integrating with API specification formats like OpenAPI and RAML
  • Generating code snippets in multiple languages to implement API calls

API Tester helps developers thoroughly test their APIs without having to write custom code for each test scenario. Its graphical interface and collaboration features facilitate rapid testing and debugging.
