Pass Data Between
Requests Dynamically.

Real API workflows aren't single requests — they're chains. Log in, get a token, create a resource, then verify it. QATESTO handles complex multi-step API flows without writing a single line of code.

  • Extract values from responses and pass to next request
  • Dynamic variables: tokens, IDs, timestamps
  • Conditional flows based on response values
  • Supports OAuth 2.0, API keys, and JWT auth

Data-Driven Testing

Test Every Scenario.
With Real Data.

Upload a CSV or connect to a database and QATESTO runs your API tests against hundreds of data combinations automatically — covering edge cases you'd never think to test manually.

  • CSV, JSON, and database data sources
  • Parameterized tests run against all data rows
  • Automatic edge case generation (nulls, special chars)
  • Schema validation against OpenAPI/Swagger specs
