Supported Countries
Express Checkout is currently available in the following countries:
🇬🇧 UK
🇺🇸 United States
🇦🇺 Australia
🇳🇿 New Zealand
🇨🇦 Canada

When creating an Express Checkout order, there are two key differences – you must specify the mode as express and set a single popupOriginUrl instead of redirectConfirmUrl and redirectCancelUrl. Unlike standard checkout, only amount, merchant, and mode are required for the Create Checkout API call:

The Data Payload Properties:

Attribute	Type	Description
`amount`	Money (required)	Total amount to be charged to the consumer. This can be dynamically updated during the checkout by setting mode to express
`mode`	String (default standard)	Set to express for an express-flow checkout. This allows the amount to adjust based on events during the checkout, such as shipping costs and sales tax based on a selected address
`merchant`	Merchant (required)	You must provide a new URL, popupOriginUrl, to receive Javascript callbacks from Clearpay (e.g. onComplete, onShippingAddressChange, etc). Include the scheme, hostname and port. Port is optional.
`items`, `discounts`, `shipping`, `merchantReference`	(optional)	Optional fields as per the API reference docs.
