error Callback

The error callback is invoked when problems occur during a payment.

Usage Copied to clipboard

The error callback must be defined using the data-error attribute on the Checkout script tag. The attribute value may be the name of a global function or a URL string.

When a URL is provided, the browser will be redirected to the new page with a query parameter appended for each argument.
