Pass a discount code to Paddle.js
We added a new parameter and HTML data attribute to Paddle.js to let you pass a discount code when opening a checkout.
What's new?
We added a new parameter to the Paddle.Checkout.open() method that you can use to pass a discount code to Paddle.js when opening a checkout:
Discount code to apply to this checkout. Use to pre-populate a discount. Pass either discountCode or discountId.
We also added a corresponding HTML data attribute:
Discount code to apply to this checkout. Use to pre-populate a discount. Pass either data-discount-code or data-discount-id.
This complements the existing discountId parameter and data-discount-id HTML data attribute, which let you pass the Paddle ID of a discount when opening a checkout.
How it works
Previously, you could pass discountId or use the data-discount-id HTML data attribute to pre-populate a discount when opening a checkout. These fields accept the Paddle ID of a discount entity.
The new discountCode parameter and data-discount-code HTML data attribute let you pass a discount code instead. This means that if you know the discount code for a discount, you don't need to make an additional call to the API or use the Paddle Dashboard to get its ID.
Discount codes are set against discount entities in Paddle. They're optional, letting you create a customer-facing code that customers can enter at Checkout, sometimes called "coupons."
Examples
This example shows a discount code passed to Paddle.Checkout.open().
There's no settings object, so checkout settings must be included in Paddle.Initialize().
