Build with AI 1 package

A build package is every page for one task, with the API operations they use. Copy the prompt into a coding assistant, or hand it the package itself: slim links to each page, full inlines all of them in one document.

Raised when an individual collection succeeds. Beta, subject to change.

Delivered by Svix, with svix-id, svix-timestamp and svix-signature headers. Verify the signature with the webhook's secret before acting on the contents.

Authentication

Ozow sends no credential with this call, so this check is the only thing standing between a real delivery and a stranger’s. Verify the delivery signature before acting on the contents: your notification URL is public, and anyone can post to it.
