Payer

If payer wants to fund payments using Pay Money, set payer to Pay Money.(Other payment method ex: paypal, stripe, coin payments etc not available yet).

//Payer Object
$payer = new Payer();
$payer->setPaymentMethod('PayMoney'); //preferably, your system name, example - PayMoney

Amount

Specify a payment amount and the currency.

//Amount Object
$amountIns = new Amount();
$amountIns->setTotal(20)->setCurrency('USD'); //must give a valid currency code and must exist in merchant wallet list

Transaction

It’s a Transaction resource where amount object has to set.

//Transaction Object
$trans = new Transaction();
$trans->setAmount($amountIns);

RedirectUrls

Set the urls where buyer should redirect after transaction is completed or cancelled.

//RedirectUrls Object
$urls = new RedirectUrls();
$urls->setSuccessUrl('http://your-merchant-domain.com/example-success.php') //success url - the merchant domain page, to
redirect after successful payment, see sample example-success.php file in sdk root, example -
http://techvill.net/PayMoney_sdk/example-success.php
->setCancelUrl('http://your-merchant-domain.com/');//cancel url - the merchant domain page, to redirect after

Payment

It’s a payment resource where all Payer, Amount, RedirectUrls and Credentials of merchant (Client ID and Client Secret) have to set. After initialized into payment object, need to call create method. It will generate a redirect URL. Users have to redirect into this URL to complete the transaction.

//Payment Object
$payment = new Payment();
$payment->setCredentials([ //client id & client secret, see merchants->setting(gear icon)
'client_id' => 'place your client id here', //must provide correct client id of an express merchant
'client_secret' => 'place your client secret here' //must provide correct client secret of an express merchant
])->setRedirectUrls($urls)
->setPayer($payer)
->setTransaction($trans);

try {
$payment->create(); //create payment
header("Location: ".$payment->getApprovedUrl()); //checkout url
} catch (Exception $ex) {
print $ex;
exit; }

A few steps on how to run this code on your device:

Example code


/***

require 'vendor/autoload.php';
//if you want to change the namespace/path from 'PayMoney' - lines[1-5] -
//to your desired name, i.e. (use PayMoney\Api\Amount;
//to use MyDomain\Api\Amount;), then you must change the folders name that holds the API classes
//as well as change the property 'PayMoney' in (autoload->psr-0) of (php-sdk/composer.json) file to your
//desired name and run "composer dump-autoload" command from sdk root
use PayMoney\Api\Payer;
use PayMoney\Api\Amount;
use PayMoney\Api\Transaction;
use PayMoney\Api\RedirectUrls;
use PayMoney\Api\Payment;
//Payer Object
$payer = new Payer();
$payer->setPaymentMethod('PayMoney'); //preferably, your system name, example - PayMoney
//Amount Object
$amountIns = new Amount();
$amountIns->setTotal(20)->setCurrency('USD'); //must give a valid currency code and must exist in merchant wallet list
//Transaction Object
$trans = new Transaction();
$trans->setAmount($amountIns);
