Hi team, I am using REST API to launch workflow as below. [http://abc.com/identityiq/rest/workflows/TestWorkflow/launch](http://abc.com/identityiq/rest/workflows/TestWorkflow/launch) Actually, we are getting response in JSON format for 200 Success. And we are getting response in Text format for Error(401,403,405..etc) How we can modify this text response in JSON format. Any suggestions, please suggest. ---

Hi Mandar, Thanks for the response. I don’t think it will work. I am using default OOTB REST API of sailpoint IIQ. I need to change the response text format to JSON when it is throwing error like 401, 403 ---

@Venkatesh0510 Is it possible for you to extract and share the request and response for both cases(success/error)? ---

@Venkatesh0510 Authentication is intercepted at the security layer before even reaching to IIQ’s rest resource. That’s why response is always test, however if any error is returned through the resource, that should be in json. Are you seeing this behavior specifically on 401s, or does it also happen on other errors within your workflow ? ---
