Can I make a phone number optional when customers book an appointment via my booking site?
I'm embedding SquareUp in my website to manage bookings and collect payments. However, as my customer's audience is not only in the US & CA, but also internationally, their phone numbers do not adjust to the current format, how can I set the phone number optional, or, how can I accept international phone numbers as well?
Thanks for your help,
