Hi, I am trying to connect square payment to itch.io

is there a way?

No, as explained in the FAQ, you can get your money through PayPal or Payoneer.

Please update your topic title to something more descriptive.

From the rules:

Use a descriptive title so others with similar issues or questions may find an answer. Titles like Help me!, Support not responding, Payouts are BROKEN, hello, etc. are not allowed. We may immediately close your topic. When you post here you are asking the community to help you, this is not a direct line of communication to site admins (that is support). Create your topic in a way that will enable others who are have a similar question to find your topic.
