How do I connect Square?

Add the Square piece to a flow, then authenticate with OAuth 2.0. Once connected, its 5 triggers and 28 actions are available anywhere in the builder.

What can I automate with Square?

"New Order" can start a flow that runs "Get Business Profile", and you can chain Square together with any of 770+ other apps and AI steps in between.

Can I self-host the Square integration?

Yes. Activepieces is fully self-hostable, so you can run the Square piece on your own infrastructure with your connections and your data staying in your environment.

Can my AI agent use Square as a tool?

Yes. Every piece you connect can be exposed over one Activepieces MCP server, so Claude, Cursor, Windsurf or any MCP client can call Square actions as tools.
