SOAP Response Validator

Validate SOAP response: well-formed XML and valid Envelope with Body or Fault. Paste raw HTTP or SOAP XML.

About this tool

Accepts a raw HTTP response (status, headers, body) or plain SOAP XML. Checks that the body is well-formed XML and has a valid SOAP envelope: root Envelope (SOAP 1.1 or 1.2) with exactly one Body or one Fault. Use after calling a SOAP API or in CI.

To validate XML against an XSD schema: XSD Schema Checker.

FAQ

Does this SOAP validator check XSD schema conformance?
It validates SOAP structure and XML correctness. For strict schema conformance, validate against XSD separately with XSD Schema Checker.
Can I validate raw HTTP response output from APIs?
Yes. You can paste raw HTTP response text; the tool extracts and validates SOAP XML from the payload.
Is this useful for CI checks?
Yes. Use it to pre-validate SOAP payload quality during testing and prevent parser/runtime failures.
