Site claiming webhook support

For Netlify integrators and AI agents deploying to Netlify, the process of “claiming” sites allows an end user to transfer a site into their ownership. It has been a challenge for systems to know when this happens.

Today, Netlify added support for an optional claim_webhook field when generating a site claim token. This lets you receive a POST request to a specified webhook URL once a user successfully claims a site.

Why is this useful? Now, your system or AI agents can automatically react when a site changes ownership—whether that’s updating internal records, triggering notifications, adjusting billing, or syncing permissions. The webhook payload includes key details like the site ID and the new owner’s account ID, making it easier to track and integrate site claims into your workflow seamlessly.
