Set up Square payments
Square setup is a two-part process: connect your Square account at the account level, then enable Square and assign a location for each venue.
Add Square to your integrations
Find "Square" in the integration list and click **Add**. Review the integration details and confirm. Square now appears in your enabled integrations.
Connect your Square account
Click **Connect**. A Square authorization window opens. Sign in to your Square account and grant Rex the requested permissions. The window closes automatically when authorization completes. The status badge changes from "Disconnected" to "Connected."
Enable Square on a venue
Toggle **Enable Square** on.
Select a Square location
In the same Square settings panel, open the **Location ID** dropdown. Select the Square location that corresponds to this venue.
Configure additional payment methods (optional)
Toggle any of the following payment methods on or off depending on what you want to accept at this venue: - **Cash App Enable** — Accept Cash App payments through Square. - **Afterpay Enable** — Accept Afterpay (buy-now-pay-later) payments. - **Bank Account Enable** — Accept ACH bank account payments on Square invoices. Click **Save** when done.
Set Square as the venue payment processor
In the **Payments** dropdown, select **Square**. Square only appears as available after you complete steps 3 and 4. Click **Save changes**.
