Support for SOAP headers and body mapping
SOAP body mappings
REST invokes with JSON/XML and multipart data for POST/PUT methods are automatically converted to SOAP.
For GET calls, you must map using query or path parameters only.
SOAP headers mapping
SOAP headers are retrieved from the WSDL of the API. You can map the values for these headers from path, query, or header parameters using the input REST invoke from the client. API Gateway removes the unmapped SOAP headers when sending the request to the native SOAP API.
Note:
Use XPaths that are relative from the SOAP envelope. For example, use an XPATH as //soap:header/headerValue and not /soap:envelope/soap:header/headerValue.
