Webhooks

Webhooks are configured on the mailbox or phone number resource, no separate registration step.

Set a URL on a mailbox to receive message.received and message.sent events.

Set an incoming call webhook URL and action on a phone number.

See the Signing Keys page for details on creating and rotating keys.

Use verify_webhook / verifyWebhook to confirm that an incoming request was sent by Inkbox. Pass the plaintext key from your signing key as the secret.
