print(data["call_sid"], data["masked_number"])We dial Party A first. When they answer, we bridge Party B. Both see the masked number as caller ID. The response includes a call_sid you can use to poll status or fetch the recording. Read the full developer documentation for every endpoint, webhook, and error code.
Six endpoints cover the full call lifecycle. All requests authenticate with a Bearer token from your API key.
Dials Party A first, bridges Party B on answer. Both parties see the masked number as caller ID. Returns immediately with a call_sid.
Returns current call state. Poll every 2-3 seconds until terminal (completed, failed, no-answer).
Returns a short-lived signed URL streaming the MP3 recording. Valid for 1 hour.
Paginated call history with filters for status and date range. Up to 100 per page.
