Integrating with square restaurant/bar POS

From all the research I’ve done, including speaking with square on slack, it seems that there is no sandbox environment for integrating with their restaurant/bar POS offering. So my quesiton is, has anyone else done this and if so, how did you go about testing it not in a live environment?

:wave: Currently with our POS offerings there isn’t a sandbox. You’ll need to test in production and refund any payments taken in production so you won’t pay any fees. :slightly_smiling_face:
