Hi, we're testing a SOAP API, test with hard-code in portal is successful.
Now we want to know how to allow API consumer to use this API in the real world.

Setting : SOAP pass-through
Test WSDL : in my prior post here

## Requirement 1 :

How does API consumer provide subscription key at their end ?
We download the WSDL and use SoapUI to test it, not sure how to map the subscription key to the XML request.

## Requirement 2 :

How do we parameterize the backend credential info by policy ?
Different operation is asked to use different credential to hit the backend, and credentials are stored in APIM.
Ex : Edit Operation should use EditUserAccount to access the backend, Get Operation should use GetUserAccount

Here's a valid payload from current test via portal , where <soapenv:Header> entails backend credential I need to parameterize now.

Not sure if policy can achieve this requirement.

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"

Need your advice, Thank you very much
