Cancel a scheduled message

Cancel a message that was scheduled with scheduled_at but has not been delivered yet. The message is removed from the sending queue and deleted. This action cannot be undone.

Only a scheduled message still in pending can be cancelled: a message already sent, delivered or failed returns 409, as does one that was never scheduled (it is delivered on submit, so there is nothing to call back).
