AccountAITranscription

Fires when a call's transcription and summary have finished processing — after the call has ended, not when it ends. Requires AI transcription to be enabled on the account.

Field	Type	Description
id	integer	The transcription id. Use it to deduplicate.
callId	string	The call — matches call history and the recordings endpoint.
bridgedCallId	string	The call this one was bridged from, if it was transferred.
agentFirstName / agentLastName / agentEmail	string	The agent on the call.
direction	string	inbound or outbound.
callerType / calledType	string	What kind of party each end was.
callerNumber / calledNumber	string	The two ends.
callerIdInternal / externalCallerId	string	Internal extension and external number presented.
callerNameInternal / externalCallerName	string	The corresponding names.
startTime / endTime	string	RFC 3339 UTC — the call's span, not the transcription job's.
language	string	Detected language of the audio.
transcription	array	The segments — see below. Absent when there is no transcript.
summarizationData	object	AI summary. Absent when summarization did not run. Shape varies.
webhookType	string	Always AccountAITranscription.

transcription[]

Field	Type	Description
start	number	Seconds from the start of the audio. Fractional.
end	number	Seconds from the start of the audio. Fractional.
speaker	integer	Diarization index — 0, 1, …
text	string	What was said.

:::caution speaker is an index, not an identity 0 and 1 distinguish voices; they do not tell you which is the agent and which is the caller, and the mapping is not stable between calls. Infer it from context — who speaks first, or match against the agent fields — and do not hardcode speaker: 0 as the agent. :::

summarizationData has no fixed schema

Its keys come from the summarization model and change as that model does. Store the whole object as JSON rather than a column per key. Internal-only scoring fields are stripped before delivery; the rest are camelCased.

Timing

This arrives after the call's AccountEndedCalls event — transcription runs on the recording, which is written after hangup. The delay depends on call length and queue depth, and for a call that was not recorded it never arrives at all.

Gotchas

• Not every call gets one. Transcription is opt-in and depends on recording being on. Silence is normal.
• transcription is absent, not [], when there is no transcript. Same for summarizationData.
• Transcript text carries the same privacy weight as the audio — and it lands on an unverified webhook endpoint.
