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 positive counterpart to the agentMissedTransfer event, and can be used to track successful handoffs.

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