HTML data attributes
Use HTML data attributes to pass parameters to a checkout, rather than using JavaScript properties.
You can use HTML data attributes to open a checkout with settings, items, and customer information. They're typically used with overlay checkouts.
Data attributes support all the same properties as the Paddle.Checkout.open() method, letting you:
- Set the initial items list or transaction that this checkout is for
- Set checkout settings, like the theme
- Prefill checkout properties, like customer email and country
- Send custom data to Paddle
Set data attributes on the element that you've turned into a Paddle Checkout button to open a checkout with the properties.
You must include Paddle.js and call Paddle.Initialize() to use HTML data attributes, but you don't need to use any other JavaScript if you're working with an overlay checkout. This is ideal when working with a CMS that has limited customization options, or if you're not comfortable with JavaScript.
