Splitit Payment Gateway for Commerce Documentation



Once installed, navigate to Commerce in the MODX manager. Select the Configuration tab and then click on Modules. Find Commerce_Splitit in the module list and click on it to make a window pop up where you can enable the module for Test Mode, Live Mode, or both. Note that while Commerce is set to test mode, Commerce_Splitit will automatically use the sandbox API. Setting Commerce to Live Mode will use Splitit's production API.

Now the module is enabled, you can click on the Payment Methods tab on the left. Then click Add a Payment Method. Select Splitit from the Gateway dropdown box and then give it a name e.g. Splitit. Next, click on the availability tab and enable it for test or live modes and then click save.

After saving, you'll see a Splitit tab appears at the top of the window. Here you can enter your Splitit API credentials: Username, password, sandbox API key and production API key. If for some reason you only have the one API key, enter it for both.

Congratulations! Splitit should now appear as a payment method a customer can use during checkout.

Form Styling

Splitit provides its own CSS for the payment widget and this is enabled by default. If you would like to completely restyle it from scratch, you can disable the system setting under the Commerce_Splitit namespace use_default_css.

Payment Wizard Configuration

New in version 1.1.0-pl

Two new system settings are offered to allow you to configure the payment wizard. You can now set the number of installments the customer can pick from, as well as the percentage of the first installment.

System Settings

  • commerce_splitit.first_installment_percentage - Value should be an integer or a float. Don't include the percentage (%) symbol.
  • commerce_splitit.num_of_installments - Value should be a comma-separated list of integers. Example: 2,3,4,5,6

New in 1.1.1-pl

Patch release. Fixed a bug that would sometimes prevent the Splitit form from displaying when using the first_installment_percentage system setting.
