Settings → Square Terminal: card payments from the appointment.
- At developer.squareup.com create an application: Applications → +. Open its Credentials.
- Copy the Application ID and the Access token (Production for real payments). The Location ID is under Locations.
- In the program open Settings → Square Terminal, paste the three values and pick the Environment: Sandbox to try, Production for real payments.
- Save, then Test connection.
- Pair new terminal — on the Square terminal type the code the program shows; it then appears in the list (“Refresh list”).
- Tips: Off, or On — “ask after Confirm”; the percentage options separated by commas, for example
15,20,25. - Card fee: the salon pays (no extra line) or the client pays — Square adds a line (credit cards only, per NY rules).
From then on the appointment has a card-payment button: the amount goes to the terminal, the client taps the card, the receipt goes to them. Pro / Max
