Wix

This guide describes how to integrate Sezzle into your Wix website so that you can provide Sezzle as a payment option for your customers. After integrating Sezzle, your site will:

  • offer Sezzle as a payment option on the checkout page.
  • refund Sezzle payments from your Wix order management system.
  • display Sezzle promotional messaging.
  • authorize and capture payments.

Integration Steps Overview​

  1. Add Sezzle to your store as a payment method
  2. Test your integration

Before You Begin​

  1. You should have a Sezzle merchant account.
  2. Make sure you have the following Sezzle details handy.
  1. Familiarize yourself with the transaction flow when buying with Sezzle.

Add Payment Method​

  1. From your Wix store dashboard, select Settings, and Accept Payments.
  2. Choose the See More Payment Options link at the bottom of the page.
  3. Locate Sezzle in the list, and choose Connect. This takes you to the Connect Sezzle page.
  4. Enter your API Keys from the Sezzle Merchant Dashboard, and choose Connect. Sezzle will now be available as a payment method at checkout.

Validate​

Step through a test checkout to validate the integration is properly installed.

Troubleshooting​

For account connection problems, check the following:

  • API Keys were entered correctly.
  • To avoid typos or extra spaces, use the Copy icon in the Sezzle Merchant Dashboard.
  • If you have multiple accounts with Sezzle, each store has its own merchant ID and API Keys that are tied to the store's URL.

If Sezzle does not appear as a payment option during live testing:

  • Ensure that Sezzle is activated as a payment provider on your site.
  • Go to Settings > Accept Payments and ensure that "Accepting Payments" is displayed for Sezzle.
