Calling Webhooks

Transcript status callback

Sent to your status_url when the call's transcription is ready. calling.transcript.completed includes the transcribed text; calling.transcript.failed means the call could not be transcribed.

Status callbacks are advisory, best-effort notifications — delivery can be delayed or fail silently, so don't gate time-critical actions on receiving one. See Status callback reliability.
