When two partner accounts are merged, the
sourcePartner account is collapsed into the
targetPartner account. The source partner’s enrollment in the program no
longer exists after the merge, so any future API calls or webhook events for
this partner will reference targetPartner.id instead.If you store partner IDs in your own system, listen to this webhook to update
your records to use the targetPartner.id.{
