Third Party Method

The "Third Party" method is when a customer leaves the site to make a payment and returns when the payment is complete.

Define a function named "area" inside the class in the module. With this function, you can present an "HTML" content to the customer.

If you need a credit card form, take a look at the "Merchant" method document.

If your payment service provider supports the REFUND feature, see the "Refunds" document.


The system variables, user variables and invoice variables you need are described below.

You can use the variables specified in the example in the "config_fields, area, capture" functions.

You must call the "set_checkout" function beforehand to use it within the "callback" function. Otherwise, customer variables and invoice variables cannot be obtained. The "set_checkout" function is explained in detail in the "callback" document.

In the "area" function, you need to present an "HTML" content to the customer in order to make a payment transaction. Usually a payment form or "IFRAME" is shown.

Example Source Code:

public function area($params=[])
    $merchant_id = $this->config["settings"]["example1"] ?? 0;
        '<form action="" method="POST">
            <input type="hidden" name="merchant_id" value="'.$merchant_id.'">
            <input type="hidden" name="amount" value="'.$params["amount"].'">
            <input type="hidden" name="currency" value="'.$this->currency($params["currency"]).'">
            <input type="hidden" name="custom_id" value="'.$this->checkout_id.'">
            <input type="hidden" name="description" value="Invoice Payment">
            <input type="submit" value="'.$this->lang["pay-button"].'">
