This SDK is a way to install the Sezzle widget onto a merchant's website that does not communicate with Sezzle's server. All the widget code, custom configuration, images, and stylesheets are stored locally within the store theme. This approach means slightly faster load speed, and greater merchant control over the widget - the Sezzle team cannot make changes to the widget, for better or for worse.
Using npm:
npm install @sezzle/sezzle-static-widget
Within your product page, add the following code snippet where you want the widget to render, updating the path to node_modules for your file structure:
<script type="text/javascript" src="../node_modules/@sezzle/sezzle-static-widget/dist/bundle.js"></script>
<script>
const renderSezzle = new AwesomeSezzle({
amount: `${yourPriceVariableHere}`,
});
renderSezzle.init();
</script>Use the Configuration options below to customize the widget appearance as desired.
- Note: Implementation varies greatly by platform, theme, etc. Below is a general overview of the process. The code snippets below are samples and may need to be modified to fit your site. For Shopify merchants, please proceed to the next section.
Create a new Javascript file within your site's code where appropriate.
Copy+paste this minified code into the newly created file.
Import the new file into the page(s) where the Sezzle widget will be added.
<script src="../scripts/sezzle-static-widget.js"></script>Create a placeholder element where the Sezzle widget should be rendered on the page(s), usually below the price container element:
<div id="sezzle-widget"></div>Add the following script below the placeholder element, updating the amount value to reflect your price variable which renders the current product price or cart total as applicable.
<script>
var renderSezzle = new AwesomeSezzle({
amount: `${yourPriceVariableHere}`,
});
renderSezzle.init();
</script>Preview your changes to confirm the widget is displaying correctly in each of the following scenarios
- Regular Price
- Sale Price
- Variant Selection
- Desktop
- Mobile
Use the Configuration options below to customize the widget appearance as desired.
