Sezzle Widget Chrome Extension
We also offer a Chrome extension that aids in the integration of Sezzle's sales widgets. The Sezzle Merchant Widget Extension is intended for Sezzle's merchant partners to add, customize, and/or disable widgets on their eCommerce site without the assistance of the Sezzle widget team. Adjust the widget's style, position, and content using the extensions popup interface. The extension can be found here.
