README

For a payment transaction we have to request a payment via web service. If our request is successful the IPG will return a token which we should use while redirecting customer to payment page. Customer will be redirected back to our desired URL(callback URL) from payment page via a GET request carrying data which may be used to check and verify customer's transaction using web service.

Request payment

For a payment transaction we should send a payment request to IPG and acquire a token. This may be accomplished by calling getToken method.

Instantiating an IPG object

for instantiating an IPG object we should call Dizatech\RayanpayIpg\RayanpayIpg constructor passing it an array of required arguments containing:

• merchantId: your payment gateway merchant id

Code sample:

$args = [
    'merchantId'    => '4e1598fc-09b8-29e6-2edc-bf5494616b4d'
]; //Replace arguments with your gateway actual values
$ipg = new RayanpayIpg($args);

getToken method

Arguments:

• amount: amount in Rials
• redirect_address: URL to which customer may be redirected after payment

Returns:

An object with the following properties:

• status: success or error
• token: in case of a successful request contains the generated token which may be used while redirecting customer to payment page
• message: contains error message when status is error

Redirecting customer to payment page

If status property of the result of calling getToken is success we can redirect customer to payment page URL which is currently https://pms.rayanpay.com/pg/startpay/. We have to redirect user to payment page via a GET request.

It is neccessary to save the acquired token token for further use

Code sample:

$args = [
    'merchantId'    => '4e1598fc-09b8-29e6-2edc-bf5494616b4d'
]; //Replace arguments with your gateway actual values
$ipg = new RayanpayIpg($args);
$amount = 1000; //Replace with actual order amount in Rials
$redirect_address = 'http://my.com/verify'; //Replace with your desired callback page URL
$result = $ipg->getToken($amount, $redirect_address);
if( $result->status == 'success' ){
    header('Location: https://pms.rayanpay.com/pg/startpay/' . $result->token);
    die();
}
else{
    echo "Error: {$result->message}";
}

Payment verification and settle

After payment the customer will be redirected back to the callback URL provided in payment request phase via a GET request carrying all necessary data including:

• Authority: Payment token by which the user has been redirected to payment page
• Status: Payment status which should be ‍OK for successful payments

If Status equals OK we can call the verifyRequest method to verify payment.

verifyRequest method

Arguments:

• amount: Original order amoun tused in payment request
• token: Authority parameter returned by IPG

Returns:

An object with the following properties:

• status: success or error
• message: message describing the status
• ref_id: reference id in case of successful transaction

Code sample:

$args = [
    'merchantId'    => '4e1598fc-09b8-29e6-2edc-bf5494616b4d'
]; //Replace arguments with your gateway actual values
$ipg = new RayanpayIpg($args);
$amount = 1000; //Replace with actual order amount in Rials
$result = $ipg->verifyRequest($amount, $_GET['Authority']);

Getting success status in response means that the transction is successful and settled.
