Cancel a booking

POST
/v1/public/bookings/{token}/cancel
curl --request POST \
--url https://api.keptslot.com/v1/public/bookings/example/cancel

This endpoint cancels the booking the token identifies. The token is the only credential.

The service’s cancel notice applies. If the notice window has closed, the endpoint refuses the request. Read can_cancel first to avoid a failed call.

A cancellation clears the token. Then the same token gives a 404.

Rate limited at 30 requests a minute for one caller address, shared across every route under /v1/public.

The booking is cancelled.

string
param

The field that caused the refusal, if one field did.

string
dimension

The plan limit that refused the request. It is present only on a 402, and only for a secret key or an account key. See the errors guide.

string
used

The current count for that dimension. It is present only on a 402, and only for an account key. It is absent when the refusal has no count to report. Absent and zero are different answers.

integer format: int64
limit

The cap for that dimension. It is present only on a 402, and only for an account key. A cap of zero is a real value.

This endpoint’s request budget is spent. The type field is rate_limited.

The budget is a token bucket, not a calendar-minute counter: it refills CONTINUOUSLY as time passes, a few tokens’ worth every second, rather than resetting all at once at the top of the minute. There is no wall-clock boundary to wait for. A REFUSED request costs nothing – the check happens before a token is spent, so hammering this endpoint while refused does not delay when it starts working again. What you get back is Retry-After: seconds until the bucket has refilled enough to admit one more request, computed from exactly how empty the bucket is right now. Retrying before then just gets refused again; retrying at or after Retry-After succeeds. See the endpoint’s own description for the actual numbers – they differ by endpoint and, for the publishable-key routes, by whether the budget is shared by the whole workspace or is one caller’s own share of it.

The response also carries RateLimit-Remaining (requests left in the bucket – always 0 on this response, since a refusal only happens once it reaches zero). Both headers are ADDITIVE: type alone is enough to act correctly, and a client that cannot read response headers loses nothing. Access-Control-Expose-Headers names both, so a browser-based integration on a publishable key can read them too, the same as it reads type from the body.
