Hi Bryan, thanks for the response. I understand that I can build a custom booking site with Square APIs (which I already did), but I’m now facing another issue: When I create a booking via the Bookings API, the **confirmation email is only sent to the customer** , not to the business owner. And I think someone else have this issue too > [@"Booked By'/creator\_details field in API bookings](https://developer.squareup.com/forums/t/booked-by-creator-details-field-in-api-bookings/22810): > > Hi there, I’m having some trouble with my booking implementation with Square’s API. Through my web app, when I create a booking with bookings.create({bookingRequest}), the creator\_details field (Read-Only) sets the details to be such that the person who booked the appointment is the Owner of the Square account, rather than something like having the creator\_type be “CUSTOMER”, or even the Team Member that it is booked with. The reason this is an issue for me, is because normally when a service… On Square’s first-party booking site, the owner normally receives a “new booking” notification. However, for API-created bookings, this doesn’t seem to happen. This is important for us operationally, since we need to be notified immediately when a new appointment is created.
