We currently call the privacy api deletion endpoint and then poll for status until we see the deletion has been completed.
We have noticed during testing that analytics returns "status": "complete" and "message": "success" regardless of whether a customer existed in the system prior to the deletion request, which is a concern for our data governance team. Customer Care have advised that this is the current expected behaviour.
Other products such as Target and Audience Manager, make this distinction by responding with status = complete but with the following additional detail:
Audience Manager: "message": "Not applicable - Unable to resolve the user ids referenced in the request", "responseMsgCode": "PRVCY-6052-200", "responseMsgDetail": "Unknown user IDs are not applicable for this product."
Target: "message": "Not applicable - user context not found"
Are there any plans to introduce this depth of information to the analytics product response?
