Connects

Example call

A caller wants a 45-minute coaching session. The receptionist reads TidyCal's open slots and books Friday at 9am through the API. The coach sees the booking in TidyCal, with AssistCall's call summary in their inbox.

During a call, the receptionist reads open time slots for a booking type from TidyCal's API with your personal access token.
The caller is booked into the chosen slot with POST /booking-types/{id}/bookings while still on the line.
When a caller asks to cancel, the receptionist cancels their TidyCal booking through the API's cancel endpoint.

How it connects

Webhook: Signed JSON for every call, message and booking, sent to any HTTPS URL you choose.
Live API actions: During the call, the receptionist calls the app's API with your key to look up or create records.
Zapier: Send AssistCall events to a Zap (Webhooks by Zapier, Catch Hook), then use the app's Zapier actions. Needs a paid Zapier plan.
Make: Start a Make scenario with a custom webhook and use the app's Make modules.
n8n: Start an n8n workflow with a webhook node, then call the app with its node or an HTTP request.
Call forwarding: Forward your business line to AssistCall when busy, after hours or always. Works with any carrier.
