If your shoppers see Sezzle as an option, but it’s not redirecting them to our site, it’s likely a problem with your API keys. You will just need to re-copy/paste both the public and the private API keys that we provide in your Sezzle account into your Shopify account.
You can get your API keys by clicking here, and then you’ll want to log into your Shopify dashboard. We recommend having two tabs open, one of Sezzle and one of Shopify since you’ll need to go back and forth.
In your Shopify dashboard, navigate to “Settings,” “Payment Methods,” “Alternative Payment Methods,” and then click “Edit” next to Sezzle. Paste in both the public and the private keys from our site into Shopify (it’s normal for the private key to turn into dots). Once you save the change, we recommend trying a test checkout to make sure that you get redirected to the Sezzle login screen after completing the order. Once that happens, your checkout is fully functional - you do not need to actually sign up and place an order.
