Map a Third-Party User ID to T&T

Build the mapping by making an mbox request with the parameter:


For example:

T&T logs the third-party ID or pcId when it writes the profile to the database (after a delay of about 30 minutes). After the third-party ID or pcId is logged, you can use the API to send more requests and use the third-party profile ID instead of the mboxId. For example:​&mbox3rdPartyId=acmecorp&​mboxParam=value&profile.Name=value&version=1

Parameters and values are case sensitive.
