Help Needed: SOAP Update Operation via MuleSoft Integration from SailPoint ISC (Web Service Connector)

[mevenky (Venkatesh Devarapalli)]

Hi everyone,

We’re currently implementing a Web Service integration via MuleSoft from SailPoint Identity Security Cloud (ISC) to perform update operations on a target system.

Here’s the setup and what we’re facing:

• Integration flow: SailPoint ISC → MuleSoft API → Target web service

• Payload format: SOAP XML (MuleSoft converts SOAP → REST → Target)

• Authentication: Azure AD OAuth 2.0 (client credentials)

• Connector type: Web Service Connector

• Rule used: Before Operation Rule (to build SOAP body and set headers)

Current Issue:

• We are getting the following exception when performing the Modify operation:

  Exception occurred while performing 'Modify' operation on identity '1056':  
  Error executing before operation rule for endpoint 'Add Entitlement-RoleId':  
  bsh.EvalError: Method put(java.lang.String, java.lang.String) not found in class 'sailpoint.connector.webservices.EndPoint'
  
  

• The SOAP request payload and OAuth token are generated successfully, but the update call to MuleSoft fails with HTTP 406 (SCHEMA_VALIDATION/APIKIT_ERROR).

• The MuleSoft team confirmed that the API accepts both JSON and SOAP payloads and automatically transforms between them.

Questions:

1. For SOAP integrations via MuleSoft, what’s the recommended configuration for the Web Service connector source in ISC (Content-Type, SOAPAction, etc.)?

2. In a Before Operation Rule, should we use requestEndPoint.setBody() and setHeader() for SOAP, or should we return a Map as in a Before Sending Rule?

3. Has anyone successfully configured a SOAP → MuleSoft → REST flow for update operations? Any working examples or best practices would be great.

What we’ve tried:

• Switched between application/soap+xml and text/xml

• Adjusted SOAP Action header

• Removed SOAP envelope (also tested with envelope)

Any guidance, working examples, or configuration recommendations would be appreciated!

Thanks in advance,
Venky

Why use mulesoft as the middleware in this case? Seems like an extra unnecessary layer of complexity
