Frequently asked questions

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. Works with WordPress, Jimdo, Squarespace, Wix, plain HTML — anywhere.

REST API and webhooks are planned for the Max plan but not yet generally available — they are activated per business on request. Access is then restricted to your own account: you only read and write your own data. If you're planning an integration, talk to us before signing up — we'll clarify the current status for your case.

The API uses bearer token authentication. Your API key is sent in the Authorization header of every request. Keys can be rotated or revoked at any time. There are no OAuth flows for third-party integrations — that's a deliberate choice to keep the attack surface minimal.

That's what webhooks (push) and the REST API (pull) are for — a typical use case: a new booking in Slotara automatically triggers a task in your CRM or a message in Slack. Both require the Max plan and are not yet generally available; activation happens per business.

Not yet — a dedicated test environment is planned for Q3 2026. For testing, we recommend using a separate account as a test tenant.
