Connect Square in Sparkforge under Payments > Integrations to process one-time and subscription payments across order forms, invoices, stores, forms, memberships, and payment links. SaaS and re-billing not supported yet.

Sparkforge supports Square as a payment processor for subaccounts. Connect under Payments > Integrations using your Square API keys to start processing payments without leaving the platform.

What Square supports inside Sparkforge

Once connected, Square handles one-time and subscription payments configured under Payments > Products. That covers:

  • Order forms
  • Invoices
  • Online stores
  • Forms
  • Memberships
  • Payment links

SaaS Mode and re-billing are not supported with Square at this time.

Track payments under Payments > Orders and Payments > Transactions. All existing payment-related triggers work with Square out of the box.

Connect Square in test mode

  1. Log into your Square account at https://app.squareup.com/login.
  2. Open the sandbox account from the Square dashboard and stay signed in as the sandbox user.
  3. In Sparkforge, click Connect next to Square Test Mode. Sparkforge picks up the signed-in sandbox account automatically.

Locations and reconnects

  • After connecting, the Sparkforge Integrations page lists every physical location on your Square account. Pick the one to associate with the subaccount.
  • Existing customers can click Reconnect to refresh the location list.
  • A default physical location is selected automatically on connect or reconnect — change it if you need a different one.
