onChargeUpdated callback

The onChargeUpdated callback, like its name suggests, is invoked when the charge changes. This means that this function will be called when a cryptocurrency transaction is created, or when a confirmation is detected, or when the charge expires, and so on.


If you need to write some important logic around these events then you should use a Webhook instead because this function will not be invoked if the Checkout widget was dismissed.

charge argument

The callback's only argument is the charge object. You can use this to check what the charge's status is.

// ...other required properties
onChargeUpdated: charge => {
switch (charge.statusCode) {
case 200:
// Processing
case 300:
// Success
case 400:
// Failed

You can review the other required properties in the main Checkout section
