Webhooks.

CodeB will POST a signed JSON payload to each configured URL when an event fires. The signature is in the X-CodeB-Signature header as sha256=<hex> over the request body using the webhook’s secret. The bridge fires events automatically when calls happen; the Test fire button validates your endpoint at any time.

New webhook

The secret is generated once when you create the webhook and shown ONCE. Save it somewhere safe — you will need it to verify the signature on incoming events. After this dialog closes, only the first few characters of the secret will be visible.

URL Events (check what to receive — payload schemas)

* (everything) call.started call.answered call.transferred call.ended outbound-ai.finished transcript.saved share.created share.viewed share.revoked

The nine events above are everything the bridge fires today. The webhook.test event from the Test fire button is delivered regardless of subscription.

Test fire

A synthetic webhook.test event is being sent to the configured URL with a real HMAC signature.
