@Sara_ I'm not using Wix, but it's not a friendly platform to integrate to.

From what I could find out, it may be possible by using Wix's API, but it will require some investigation and integration to make it work.

My suggestion is to use a booking link to capture the booking, then integrate it to Manychat using Zapier to send the customer notifications - such as 'thank you for booking' or 'you have an appointment tomorrow, please confirm'.

If you want help setting these up, feel free to reach out.
