complete Callback

The complete callback will be invoked when the payment has been completed.

Usage Copied to clipboard

The complete callback must be defined using the data-complete attribute on the Checkout script tag. The attribute value may be the name of a global function or a URL string. URLs will have a query parameter appended for each argument.

The complete callback is only supported in a Return To Merchant integration.
