Litepay.ch class for our Merchant & Payment API

Introduction

This is Litepay.ch PHP class for our Crypto Payment Merchant & Crypto Payment API. This extension allows to easily accept Bitcoin (and other cryptocurrencies such as Litecoin, Zcash, Bitcoin Cash & Monero) on your website.

To successfully use this class, you need to import it in your project & call it. If you want to use our Bitcoin Payment Merchant API, you will need to Register for Merchant account and create a VENDOR ID.

EXPLANATION

Our api requires some info from you, to be able to generate a address for your payment;

$method - Use 'btc' / 'ltc' / 'zec' / 'bch' / 'xmr' as a value for parameter method, based on entered value a Bitcoin, Litecoin, Zcash, Bitcoin Cash, Monero address will be generated $receiving_address - Your Receiving Bitcoin/ Litecoin / Zcash / Bitcoin Cash, Monero Address (Where you would like the payment to be forwarded)
$callback_url - The callback URL to be notified when a payment is received. Remember to URL Encode the callback URL when calling the create method. The domain must be valid, or else your request will be denied.

EXAMPLE

Payment API: Creating invoice

include('litepay_ch.php'); //in your file
$litepay = new litepay('api'); //using payment API 
$_secret = 'my_secret_passphrase';
$invoice_id = '123_order_number'; 
$callback_url =  'https://your_domain.com/callbacks/litepay/callback.php?id='.$invoice_id.'&secret='.$_secret; 

$method = 'btc';
$return_address = '1BDesouFJaHyr7DejtGrq7K14D5gSbS4DT';

$parameters = array(
    'address'=>$return_address,
    'method'=>$method,
    'callback'=> urlencode($callback_url)
  );

$new_address = $litepay->receive($parameters);
if($new_address->status == "success") { 
    $address = $new_address->address;
}

Payment API: Checking address

include('litepay_ch.php'); //in your file
$litepay = new litepay('api'); //using payment API 
$method = 'btc';
$parameters = array(
    'address'=>$generated_address, //the one we generated
    'method'=>$method
  );

$check_address = $litepay->check($parameters);
if($new_address->status == "success") { 
    $address = $check_address->address;
    $amount => $check_address->amount;
    $confirmations => $check_address->confirmations;
    $txids => $check_address->txids;
}

Merchant API: 1. Go to Litepay payment merchant and register for a merchant 2. Go to Vendor & create a vendor id, you will receive the necessary information in the email you used to register.

Then use them like we are showing below.

include('litepay_ch.php');
$litepay = new litepay('merchant'); //using Merchant API 


$invoice_id = 22;

//always have a valid domain in callback/return
$callback_url = 'https://domain.com/callback_url.php?invoice='.$invoice_id;
$return_url = 'https://domain.com/success.php';

$parameters = array(
    'vendor' => 'VENDOR_ID',
    'invoice' => $invoice_id,
    'secret' => 'PASSPHRASE',
    'currency' => 'USD',
    'email' => urlencode('user@email'),
    'price' => '2',
    'callbackUrl' => urlencode($callback_url),
    'returnUrl' => urlencode($return_url)
  );


$data = $litepay->merchant($parameters);
if ($data->status == 'success') {
 header("Location: $data->url");   
} else {
 print $data->message;
}
