Webhooks for expired and auction domains

A signed JSON POST when a filter matches, an auction changes, or you update a note, a favorite, or a user task. Pro plan.

Webhooks send a signed JSON POST to Zapier, Make, n8n, IFTTT, or any public HTTPS URL. You need a Pro plan. Add a subscription in Profile → Developer, or with POST /v1/webhooks and the same key as the Public API.

Three kinds:

  • Filter — domain.matched_filter when a report starts matching a saved search. Rows already in the list are not sent again.
  • Reports — watch specific reports (from favorites in the UI, up to 100). Auction price, bid count, ending soon, and ended, plus this account's note, tags, and favorite.
  • User tasks — usertask.created and usertask.completed.

Each delivery is signed with Standard Webhooks. The whsec_ secret is shown once: when you create the subscription or rotate the secret. An account can have 30 subscriptions and 5,000 deliveries per UTC day.

Setup and payload examples are on the webhooks page.
