Workspace access

Request an API key

bkinAPI keys are issued per product workspace after a short review. There is no public self-serve signup and no browser key.

What you must accept

Server-to-server only. Keys never ship in JavaScript, mobile binaries, or invitee links.
HTTPS product URL we can review, plus a reachable human contact.
Idempotency keys on writes, HMAC verification on webhooks, HTTPS webhook URLs on public DNS.
Invitee PII stays in your app unless you explicitly use managed_identity.
No unsolicited booking spam. Sandbox first if you are still integrating.
The first key is a bootstrap * secret. Replace it with scoped keys before production traffic.

Full API contract: documentation and OpenAPI.
