Square Checkout

To use this Square extension you will need the following:

  1. AbanteCart 1.3.x installed (tested up to AbanteCart 1.3.1). [This extension does NOT have support for the FastCheckout extension.]
  2. A SSL certificate provided by your Web hosting company
  3. An account with Square

In order to set up the Square extension for AbanteCart you will need to have an application (aka app) attached to your Square account. Log into your account and navigate to Apps. If you don't already have an app then you will need to create one for your AbanteCart store.

After you navigate to Apps you will see the auto-generated value for Personal Access Token and this needs to be entered on the settings page. The Location ID can be retrieved from the Location page on Square App.

This extension features the following:

  • Process all major Debit/Credit cards and accept mobile-wallet NFC payments like Google Pay and Apple Pay (depending on the customer's device)
  • Real-time validation of credit card numbers, CVV/CVC code, invalid expiration date, and more through Square's Checkout API.

The previous version, 1.1.1 has been upgraded to Square API version, 2021-08-18.

And the current version, 1.1.2 has been upgraded to Square API version, 2022-07-20. However, with the limited functionality of Square's Sandbox environment with the "update," I cannot do a full test, so use at your own risk for production/live environments.
