ABOUT THIS TOOL

Transport success is not always business success

Some integrations return HTTP 200 even when the body contains success=false, error, exception or error-message indicators. DevPayload highlights these contradictions so analysts and developers do not rely on the HTTP status alone.

COMMON USES

Useful for everyday developer work

Review 200 OK responses that still fail a business process.
Spot common error indicators in JSON bodies.
Separate transport status from likely business result.
