WhenTap

What syncs where

A single reference for everything WhenTap reads and writes, and where it goes. Nothing moves that is not listed here.

Webflow

Direction What Detail
Read CMS Collections, items and fields To turn your Collections into bookable staff, services and locations, and to suggest a write-back field mapping
Read Your site list and account email At install, to know which sites you can connect and who you are
Write A CMS item per booking Created as a draft in your chosen Collection; updated on reschedule and cancel. See Booking write-back
Webhooks Collection item created / changed / deleted Registered at install so CMS edits sync within seconds

WhenTap requests only the Webflow scopes it needs: authorized_user:read, sites:read, cms:read, cms:write, forms:read.

Google Calendar & Outlook

Direction What Detail
Read Busy times Existing events on a connected staff calendar block WhenTap slots
Write An event per booking Titled "ServiceCustomer", with the customer's email; moved on reschedule, deleted on cancel

Connected per staff member. See Connecting Google & Outlook.

Stripe

Direction What Detail
Write A Checkout session per paid booking Created on your connected account, with WhenTap's platform fee set to zero (0%)
Write A refund Issued on your account when a paid booking is cancelled

Money pays out to your own Stripe account. WhenTap never stores card details. See Taking payments with Stripe.

Email

Direction What Detail
Out Customer confirmation On booking, with the manage link and add-to-calendar buttons
Out Email reminder 24 hours before the appointment
Out Owner and staff notification On each new booking, including intake answers

The confirmation screen also offers add-to-calendar buttons, so the appointment lands on the customer's own calendar and their device reminds them natively. See Confirmations & reminders.

What stays put

Some things WhenTap deliberately does not move. It never copies your customers' card details (Stripe holds those), and it does not push your WhenTap availability or hours into your Webflow CMS, your hours live in WhenTap, your bookings live in Webflow. If you leave, your bookings are already in your Webflow CMS and your payments in your own Stripe, so nothing has to be migrated back.
