This guide explains how to add Sezzle as a payment option on your Wix website, enabling customers to use Sezzle at checkout.

​
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:
  1. API Keys were entered correctly
    To avoid typos or extra spaces, use the Copy icon in the Sezzle Merchant Dashboard.
  2. 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.
