FAQ: Developers & integration

No. The widget is a ready-made iframe snippet that you copy from the dashboard and paste into your website. No JavaScript, no configuration, no dependencies. It works anywhere your website can embed an iframe.

The public booking API is usable on every plan and documented in the dashboard after signing in. API key access — read access to your appointments — belongs to the Max plan and is additionally activated per business. Webhooks are not currently available.

The public booking API needs no key. The key API uses bearer tokens: you create the key in the dashboard after activation and send it in the Authorization header. You can regenerate it at any time; the old one becomes invalid immediately. There are no OAuth flows for third parties.

For the booking flow via the public booking API, on every plan. Your system reads appointments via the key API — Max plan, after per-business activation. Outgoing notifications to your system (webhooks) are not currently available, and there is no ready-made connector to automation services.

No, there is no separate test environment. For testing, we recommend using a separate account as a test business.
