Gateway extensions

The gateway extensions have a few hooks that you can use to process payments.

You can also use routes and views in the gateway extension.

canUseGateway

This hook is used to check if the gateway can be used. This can be used to check if the gateway is enabled, if the user has permission to use the gateway etc.

public function canUseGateway($items, $type)
{
    // Check if the user can use the gateway
    return true;
}

$items is either a list of InvoiceItem or a array with a Product, Price and Quantity.

$type is either invoice or cart.

pay

This hook is used to process the payment.

public function pay(Invoice $invoice, $total)
{
    // Process the payment
}

$invoice is the invoice that is being paid.

$total is the total amount that needs to be paid. (This can be the total amount of the invoice or a part of the total amount)
