Is it possible to apply OAuth 2.0 Client Credentials grant type on an existing SOAP service? If it is possible, what are the assertions to be used and how to pass the auth_token from SOAPUI? I tried sending the details in the Header as explained below, but it does NOT work for SOAP.
Client: SOAP UI:
Value: Bearer <auth token>
Policy Manager (Policy Config):
1) Assertion: "OTK Require OAuth 2.0 Token" (with scope string, cache 3600, false, false and access token left empty)
2) Assertion:"Return Template Response to Requestor"
OTK : 4.1
API Gateway: 9.2
Note: same policy config works for a REST endpoint.
