Welcome to the Make community!
To do this, you can try using the Square “Watch New Events” module —
Watches for new events(inventory, invoices, transactions, disputes, orders, labors) in square account.
For more information about the Watch New Events module and Square app, see the corresponding Integrations page and the Help Centre documentation.
Hope this helps! If you are still having trouble, please provide more details.
