Windmill HubTake payments and manage customers, catalog and orders from any Windmill script, flow or app.
Set up in 3 steps
Copy an access token
At developer.squareup.com/apps, open your application and choose Credentials. Take the sandbox token while you build, the production one when you go live.
Add the resource in Windmill
Open Resources, add a resource of type square, and paste the token.
Run your first script
Fork any script below and list locations — most calls need a location id.
Scripts
Building blocks, if none of the projects above fit. Fork one, run it, or call it as a step inside your own flow.

Questions
Sandbox or production?
The token decides, and the two never mix. Keep a resource for each and switch the one a flow points at.
Is my key stored on the hub?
Never. It lives only in your own Windmill workspace, encrypted at rest.
