API ReferenceWebhooks

Create a webhook

POST
/api/webhooks

Register a new outbound webhook. The plaintext signing secret is returned exactly once — store it securely.

Requires the webhooks:write scope — Create, edit, and delete your webhook endpoints.

Authorization

AuthorizationBearer <token>

API key authentication. Use a sk_* (FULL) or pk_* (SENDING_ONLY) key as the bearer token. Public keys (pk_*) are restricted to the email-send endpoints and the self-serve list subscribe/unsubscribe pair; every other endpoint — event tracking included — answers 403 for them. In scope terms (used by /api/v1/* operations): FULL keys hold every scope; SENDING_ONLY keys hold only emails:send.
