Connect First AI Employee to OnceHub.

Calendar1 routeRoute facts checked August 28, 2026

This page shows every cataloged route for this app and marks the most capable working path. The recommended route is serving now after you authorize your own account.

You authorize and keep control of the provider account. No page view means an account is connected.

Dashboard-managed connection

Your AI reads available times from the OnceHub booking calendar you select, books the caller into that calendar, and reads the returned booking back before reporting success. The connection needs the caller name and email and supports only the selected booking calendar. If OnceHub does not return and read back the same booking ID, the AI must not say the meeting is booked.

Every available route

More than one route is shown when it adds a real capability or gives you a customer-owned alternative. Recommended means most capable today, not already connected.

Before you start

What it does not do

Account ownership and data boundaries

The route sends only the event fields needed for the action you configure. Provider credentials stay in the approved connection or are sealed by First AI Employee where the guide explicitly says so.

  • Your provider and automation accounts remain yours.
  • A successful transport test is not the same as a verified provider write.
  • The pages never claim a native or two-way sync unless that exact capability exists.
