Paddle.Checkout.updateItems()

Use Paddle.Checkout.updateItems() to dynamically update the items list for an open checkout.

Typically used with inline checkout to update quantities or add addons to the checkout.

To use this method, a checkout should already be opened. Use the Paddle.Checkout.open() method to open a checkout.

Pass an array of objects, where each object contains a priceId and quantity property. priceId should be a Paddle ID of a price entity.

Paddle expects the complete list of items that you want to be on the checkout — including existing items. If you don't include an existing item, it's removed from the checkout. See: Work with lists

Use the Paddle.Checkout.updateCheckout() method to update discount and customer information, as well as items. You might do this when you need to swap or remove a discount when updating items.

Parameters

Example
