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.
