A flow to receive http response has been set up and the post back url sent to the vendor. The vendor keeps getting the following error:
2021-07-29 17:16:33 ERROR VcsHttpPostService:98: ClaimTransmission-002 51 DPS988 reject http: GeneralException while calling url Attempt 5 401 Unauthorized
When I post a sample xml to the same url via postman it works. Not clear why the vendor gets an error then.
