Webhooks

When you connect your Kit account, dough registers several webhooks to receive real-time notifications about subscriber activity. These webhooks power segmentation, engagement tracking, and automation.

Registered webhooks

Kit event	What dough does with it
subscriber.activated	Applies dietary preferences from the subscriber’s custom fields to their tags.
subscriber.tag_added	Records tag additions as engagement events for analytics.
subscriber.unsubscribed	Removes the subscriber from segment counts.
purchase.completed	Records a purchase attribution event, linking the purchase to recently saved recipes.
link.clicked	If the clicked link is a Save This Recipe URL, records a save click engagement event.

Security

All webhook payloads are verified using HMAC-SHA256 with your Kit webhook secret. Unverified payloads are rejected. dough acknowledges valid webhooks immediately with a 200 response and processes them asynchronously.

Duplicate handling

Kit may deliver the same webhook event more than once (for example, if dough’s initial acknowledgment was delayed). dough handles this by checking for existing processed records before acting on any webhook. Duplicate deliveries are safely ignored.

Note

If dough is temporarily unavailable, Kit retries webhook delivery with exponential backoff. No events are lost.
