Mock SOAP Envelope Generator
SOAP is still widely used in enterprise and government integrations, but developers who encounter it for the first time — or who need a sample to test a SOAP client — usually have to dig through verbose WSDL documentation just to find one working example message. This tool generates a minimal, well-formed SOAP 1.2 envelope with no inputs required: a click produces a complete envelope with the soap: namespace, an empty Header, and a Body containing one of four sample operations (GetUser, CreateOrder, GetBalance, UpdateRecord) with an Id and a Token element. The envelope uses the http://www.w3.org/2003/05/soap-envelope namespace and a custom service namespace at http://example.com/service. The operation name and the Id value are randomised each time. Copy the XML into a test, a mock endpoint, or a tutorial. Adapt the namespace, operation name, and element names to match the real WSDL of the service you are integrating with. SOAP services are strict about namespaces — getting them wrong typically results in an unhelpful fault.

FAQ
what does the generated soap envelope contain
A SOAP 1.2 envelope using the http://www.w3.org/2003/05/soap-envelope namespace, an empty soap:Header element, and a soap:Body containing one of four sample operations (GetUser, CreateOrder, GetBalance, UpdateRecord) with an Id and a Token child element. The operation and Id are randomised each run.
what is the difference between soap 1.1 and soap 1.2
SOAP 1.1 uses the namespace http://schemas.xmlsoap.org/soap/envelope/ and is the older, more widely deployed version. SOAP 1.2 uses http://www.w3.org/2003/05/soap-envelope and has a more formal specification. The generator produces 1.2 envelopes. If your service uses 1.1, update the namespace in the generated XML.
will the generated envelope work with a real soap service
Only after adapting it. Real SOAP services have their own namespace, operation names, and element schemas defined in a WSDL. The generated envelope shows the correct structure, but you must replace the example.com namespace, the operation name, and the child elements to match the WSDL of your target service.
why is soap so much more verbose than rest json apis
SOAP was designed for formal, contract-driven integration between systems, with mandatory envelopes, namespaces, and typed schemas defined in WSDL. That rigidity provides strong typing and tooling (WSDL-to-code generation) but at the cost of verbosity. REST with JSON has no required envelope or schema, which makes it lighter but less formally typed.
