OpenAPI servers URL mismatch with real requests

The servers array in OpenAPI must match where clients call: scheme, host, and base path. Mismatches break generated SDKs, server variables, and mock servers.

Common causes

  • Staging URL left in production spec.
  • Missing /v1 base path.
  • HTTP vs HTTPS mismatch.

How to fix

  • Validate the full spec in OpenAPI Validator.
  • Align servers with REST Endpoint Tester base URLs.
  • Version servers per environment.
