FAQ

How does breaking change detection work?

We parse your OpenAPI specs or GraphQL schemas using AST analysis on every push. We diff the old and new versions to flag removed endpoints, changed types, renamed fields, and other breaking changes — then immediately queue notifications.

Which customers get notified?

You import your customer list and tag each customer with the API endpoints or versions they use. We only notify customers affected by a specific breaking change, so no one gets irrelevant alerts.

What does the migration guide include?

Each guide is auto-generated from the diff and includes the old vs. new API signature, a code snippet showing the required change, a deprecation deadline, and a link to your docs — all sent directly to the affected customer.
