How to integrate Square with systeme.io
In this article, you will learn how to integrate your Square account with your systeme.io account.
What you will need:
A systeme.io account
A Square account registered in the US, Canada, Australia, the UK, France, Ireland, Spain or Japan (If your Square account is registered in another country, the connection will fail)
1. Setup and configuration
To connect your Square account, you first need to log in to your systeme.io account. Click on your profile picture, followed by Settings (1). Next, from the left-hand menu, click Gateways (2) under Payments.

On the payment gateways page, scroll down to the bottom and click Connect (3) next to Square.

You will be redirected to a page that allows you to log in to your Square account or to create one if you do not already have an account.

Once logged in, you will be prompted to review the permissions requested by the systeme.io integration. Scroll to the bottom of the list and click Allow (4) to authorize the connection.

Once the authorization is complete, you will be redirected back to systeme.io, and your Square account will be successfully connected.
2. Activating Square in your funnel and link in bio
Once Square is connected, the Square option will automatically appear in your funnel settings.
To offer Square on your payment pages, go to your funnel settings and check the box next to Square (1).

Square will now appear as an option on your order form!
To offer Square on your Link in bio page, enable the Square (2) option under the settings tab.

Square will now appear as a payment option on your Link in bio page!
