Square payment gateway

Does HS support Square or is it generic enough to use one of the other payment gateways? Thanks.

I couldn't find any information about such payment gateway and found that thread which seems to confirm that there is no API in order to use it on websites:

Yeah thanks for that. I did some more digging on their website (HORRIBLE site too!) once my client had given me login details and found that they don't offer web-based APIs anyway. But you had to sign up to get access to the area that answered the question - no phone number, no live chat. Designers should refuse to do such crap!
