Implementing Customer Attributes with Target - mbox3rdPartyID vs. customerId
Hello,
We are looking at implementing the customer attributes feature. I have reviewed the documentation both in the Target section as well as the "Experience Cloud Interface Component" docs.
I understand you upload customer IDs and associated attributes to the platform and that you must send this ID to the platform on the page level after the user logs in. However, based on Adobe's docs (primarily https://experienceleague.adobe.com/docs/target/using/audiences/visitor-profiles/working-with-customer-attributes.html?lang=en and https://experienceleague.adobe.com/docs/target/using/audiences/visitor-profiles/working-with-customer-attributes.html?lang=en) I am unclear on the relationship between the customerID functions from the ECID lbirary and Target's `mbox3rdPartyID`. Specifically, does one: (1) send the ID in the `mbox3rdPartyID`, (2) use `setCustomerID()`of the ECID service, or (3) both?
Thanks!
