Use AssistCall with Booker

Booker: Booking, room and equipment scheduling, payments and marketing software for day spas, hotel spas and salons.

Works alongside

Example call

A hotel guest calls at 10pm to ask about a couples massage tomorrow. AssistCall answers with your spa menu and takes the names, room or phone number and preferred time. The spa team sees the summary in the morning and books it in Booker.

Forward your spa reservation line to AssistCall when the desk is busy or after hours.
AssistCall takes booking requests with the service, date and guest count, and emails the summary and recording so the spa team can book in Booker.
Send AssistCall's call.completed events by webhook to your own system so every call is logged.

How it connects

Call forwarding: Forward your business line to AssistCall when busy, after hours or always. Works with any carrier.
Webhook: Signed JSON for every call, message and booking, sent to any HTTPS URL you choose.

About Booker's API

Partner API: the vendor approves access
Style: Not confirmed
Authentication: Not confirmed
On Zapier: no. On Make: no.

Booker is owned by Mindbody (the footer on booker.com reads Copyright MINDBODY, Inc.). Booker's site doesn't mention a public API, and the old Booker developer domain no longer resolves. We assume developer access works like Mindbody's approval-based partner program but could not confirm it. There is no Booker app on Zapier (zapier.com/apps/booker returns 404).

Not included: no one-click Booker app, no listing in Booker's marketplace, no two-way sync, and no partnership with Mindbody, Inc..
