Twilio webhooks

Incoming SMS and calls, message status changes, and call progress events.

Events

Incoming message
Message status: delivered
Call status: completed
Recording ready

Signature

Header X-Twilio-Signature: HMAC-SHA1 of '<full URL><POST params sorted by key, concatenated as key+value>' with the auth token, base64 encoded. Twilio sends form-encoded bodies.

✓ A bin checks Twilio signatures: add the auth token under Signature verification (Twilio).

Retries

Status callbacks are not retried. Incoming message and call webhooks fall back to the configured fallback URL.

See a retry schedule in the calculator.
