Webhooks let your systems respond to Builder events, such as emails being created, approved, exported or pushed.

Add an endpoint

  1. As a workspace owner or admin, open Integrations → Alerts and webhooks → Webhooks.
  2. Add an Endpoint URL using HTTPS and, optionally, a Name.
  3. Select the events your system needs and save.
You can add up to ten webhooks.

Receive events

Builder signs each event with the X-EmailLove-Signature header and retries a failed delivery up to three times. Configure your receiver to verify the signature using the connection’s signing secret and handle repeated deliveries safely. If events are missing, check the endpoint, selected events and receiver logs. Keep the signing secret private. Webhooks send Builder activity; they do not import ESP contact events or replace the reporting sync. For agents or scripts that need to read or change Builder emails, see Agents and API.
