Hi,

I can see on the product page that the Terminal, along with the USB hub allows it access to a barcode scanner, an external printer, cash drawer and other peripherals.

However from the API documentation, I cannot see anything that would allow a third party web app access to those same features that the first party software would provide access to.

Is this assumption correct? I’d love to hear if not.

Yes, your assumption is correct. The Terminal API currently does not provide direct access to peripherals like barcode scanners, external printers, or cash drawers. The API is primarily designed to manage Terminal checkout and refund requests. It does not include functionality for managing or interacting with additional hardware peripherals connected to the Square Terminal.
