In the UBX web interface the IMC is defined as an audience publisher and we set up the custom endpoint to subscribe to an specific segment from the available list from IMC.
When running the script from the UBX Toolbox to download the audience, after identifying that there are 21 files to download, the following message appears in the log ERROR HTTP Error 401: Unauthorized, and the process stopped. No files are downloaded from IMC.
What authorization is required in addition to the Endpoint registration?
By default there are a very limited number of attributes available to map at the destination endpoint (Email, first name, last name) How are additional attributes identified?
