Call Transfer Connected - Apten

The call.transfer.connected webhook event is triggered when a warm call transfer successfully bridges a human agent into the lead’s conference. This is the success counterpart to call.transfer.failed.

This webhook only triggers for warm transfers performed by the warm-transfer bot. Cold transfers will not trigger this event.
