Webhooks can be enabled in the Brella Admin Panel or via our /webhooks REST endpoints.
Webhooks are specific to a particular event. To create a webhook via the Admin Panel, navigate to your event, and visit the "Webhooks" tab under "Integrations".
If you can't see this tab, please contact your Customer Success Manager (this feature is only available upon request for customers who have purchased integrations/ API access).
The expand parameter can only be toggled via the Admin Panel (for now), not via the REST endpoints for manipulating webhooks.
