The app uses these endpoints for payment submit and payment details calls:
<your base url>/payment
<your base url>/payment/details
copied to clipboard
The plugin will send data for the payment submit call wrapped into another object like this:
{
payment: <all data for payment which has to be sent to adyen>,
additionalData: {key: value}
}

// additonalData can be used to send additional data to your own backend for payment
