Troubleshooting & FAQ

Quick answers to the questions we hear most.

I get 401 Unauthorized

Check that the key is in the Authorization header as Bearer <key> and that you are not using a test key against live data.

I get 429 Too Many Requests

Free keys allow 60 requests a minute. Respect the Retry-After header and back off exponentially.

Slots show the wrong time

All times are UTC. Convert to the visitor timezone in your UI using their browser timezone.

Is there a sandbox?

Yes. Test keys use a separate sandbox with sample calendars that reset nightly.

Still stuck? Email support@kestrel.example with the request ID from the response headers.
