Why Blockonomics bitcoin payment gateway?

The fastest and easiest way to start accepting Blockonomics Bitcoin payments on your online eCommerce website. Blockonomics has helped thousands of eCommerce sites increase sales since 2015, by including Bitcoin, Ethereum and Litecoin as their customers ‘ payment option.

In this article, I will explain to you how to integrate the Blockonomics payment gateway to accept bitcoin payment using PHP.

Step-1: Before starting first, create your merchant account with https://www.blockonomics.co/

Step-2: Create a Database Configuration file (dbconfig.php)


$host=DB_HOST;// localhost
$user= DB_USERNAME;
$pass= DB_PASSWORD;
$db= DB_NAME;
$con = mysqli_connect($host,$user,$pass,$db);  
if(!$con)
{
die("Database connection error!");
}

$host=DB_HOST;// localhost

$user= DB_USERNAME;

$pass= DB_PASSWORD;

$db= DB_NAME;

$con = mysqli_connect($host,$user,$pass,$db);

if(!$con)

{

die("Database connection error!");

}

Step-3: Create a database table to store transaction details

copy and paste the following MySQL database query script to create a ‘transaction_details’ table.


CREATE TABLE `transaction_details` (
  `trans_id` int(255) NOT NULL,
  `order_id` int(255) NOT NULL,
  `tnx_id` longtext,
  `address` longtext NOT NULL,
  `value` varchar(1000) NOT NULL,
  `bits` varchar(1000) NOT NULL,
  `status` varchar(1000) NOT NULL,
  `created_on` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

ALTER TABLE `transaction_details`
  ADD PRIMARY KEY (`trans_id`);

ALTER TABLE `transaction_details`
  MODIFY `trans_id` int(255) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=1;

CREATE TABLE `transaction_details` (

`trans_id` int(255) NOT NULL,

`order_id` int(255) NOT NULL,

`tnx_id` longtext,

`address` longtext NOT NULL,

`value` varchar(1000) NOT NULL,

`bits` varchar(1000) NOT NULL,

`status` varchar(1000) NOT NULL,

`created_on` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP

) ENGINE=MyISAM DEFAULT CHARSET=latin1;

ALTER TABLE `transaction_details`

ADD PRIMARY KEY (`trans_id`);

ALTER TABLE `transaction_details`

MODIFY `trans_id` int(255) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=1;

In the above,

tnx_id = Transaction id,

address = Bitcoin payment address,

value= Total order amount in USD,

bits= Total order amount in bitcoin,

status = payment status (-1= pending, 2= success)

Step-4: Create your callback page (callback.php)

Copy and paste below code to update transaction status after payment.


<?php
include 'dbconfig.php';

$txid = $_GET['txid'];
$value = $_GET['value'];
$status = $_GET['status'];
$addr = $_GET['addr'];
$trans_insert=mysqli_query($con, "UPDATE `transaction_details` set  `tnx_id`='".$txid."',  `value`='".$value."',
  `status`='".$status."' where `address`='".$addr."'
  "); 
?>

<?php

include 'dbconfig.php';

$txid = $_GET['txid'];

$value = $_GET['value'];

$status = $_GET['status'];

$addr = $_GET['addr'];

$trans_insert=mysqli_query($con, "UPDATE `transaction_details` set `tnx_id`='".$txid."', `value`='".$value."',

`status`='".$status."' where `address`='".$addr."'

");

Step-5: Create Blockonomics Configurations file (blockConfig.php)

Copy and paste below Blockonomics Configurations code in blockConfig.php file


/*Blockonomics Configurations*/

$CALLBACK_SECRET = secret_key; // add your own secret key string, it will be same as you will use with your call back url later

$BASE_URL = 'https://www.blockonomics.co';
$NEW_ADDRESS_URL = $BASE_URL.'/api/new_address?match_callback='.$CALLBACK_SECRET;
$PRICE_URL = $BASE_URL.'/api/price?currency=USD';
$API_KEY = YOUR_API_KEY;

/*Blockonomics Configurations*/

$CALLBACK_SECRET = secret_key; // add your own secret key string, it will be same as you will use with your call back url later

$BASE_URL = 'https://www.blockonomics.co';

$NEW_ADDRESS_URL = $BASE_URL.'/api/new_address?match_callback='.$CALLBACK_SECRET;

$PRICE_URL = $BASE_URL.'/api/price?currency=USD';

$API_KEY = YOUR_API_KEY;

Step-6: How to get API_KEY and set Callback URL

Callback URL should be like


https://www.tutorialswebsite.com/callback.php?secret=CALLBACK_SECRET

// CALLBACK_SECRET string should be same as you defined in blockConfig.php file

https://www.tutorialswebsite.com/callback.php?secret=CALLBACK_SECRET

// CALLBACK_SECRET string should be same as you defined in blockConfig.php file

Step-7: Create a payment page (payment.php)

When your e-commerce website will process checkout then you need to store cart items details and customer details into the database. After inserting the order details, you need to get generated order id and pass generated order id and total order amount to payment.php file.


<?php
include 'dbconfig.php';
include 'blockConfig.php';

$order_id = 1234;
$total_order_amount= 10; //(USD)

//return here if cart is empty
if(!isset($order_id)  && empty($order_id)) {
   header("Location:error.php");
}

$data = '';


$options = array( 
    'http' => array(
        'header'  => 'Authorization: Bearer '.$API_KEY,
        'method'  => 'POST',
        'content' => $data
    )   
);  

//Generate new address for this invoice
$context = stream_context_create($options);
$contents = file_get_contents($NEW_ADDRESS_URL, false, $context);
$new_address = json_decode($contents);

//Getting price
$options = array( 'http' => array( 'method'  => 'GET') );  
$context = stream_context_create($options);
$contents = file_get_contents($PRICE_URL, false, $context);
$price = json_decode($contents);

if(isset($total_order_amount) && !empty($total_order_amount)){
$total_cost = $total_order_amount;
}else{
    header("Location:error.php");
}
//Total Cart value in bits
$bits = intval(1.0e8*$total_cost/$price->price);
$status=-1;

$tnx_query="select * from `transaction_details` where `order_id`='".$order_id."'";
         $tnx_orderitem=mysqli_query($con,$tnx_query );
         $getTnx=mysqli_fetch_array($tnx_orderitem);
         
        if(count($getTnx)==0){ 
            
$trans_insert=mysqli_query($con, "insert into `transaction_details` set `order_id`='".$order_id."',`tnx_id`='', 
`address`='".$new_address->address."',`value`='".$total_cost."', `bits`='".$bits."',`status`='".$status."'"); 
}else{
     $trans_insert=mysqli_query($con, "UPDATE `transaction_details` set  `address`='".$new_address->address."', `status`='".$status."' where `order_id`='".$order_id."'
  "); 
}

setInterval(function()

{

$.ajax({

type:"POST",

if(resData.status==-1 && current_addr !=resData.address){

}

});

}, 1000);

});

</script>

In the above code, you can see I used ajax to check payment status. After success payment, I am redirecting the customer to thankyou.php page.

Step-8: Create a page (ajax_payment_success.php )

Copy and paste below code to check payment status after every second interval


<?php
include 'dbconfig.php)';
if(!empty($_POST["order_id"])) {
    
    $order_id=$_POST["order_id"];
   // $order_id=7;
$query ="SELECT * FROM `transaction_details` WHERE `order_id`='".$order_id."'";
$res_prod=mysqli_query($con,$query);
$product=mysqli_fetch_array($res_prod);

echo json_encode($product);
}
?>

<?php

include 'dbconfig.php)';

if(!empty($_POST["order_id"])) {

$order_id=$_POST["order_id"];

// $order_id=7;

$query ="SELECT * FROM `transaction_details` WHERE `order_id`='".$order_id."'";

$res_prod=mysqli_query($con,$query);

$product=mysqli_fetch_array($res_prod);

echo json_encode($product);

}

Step-9: Create a page (thankyou.php)

After successful payment redirect the customer to thank you page where you can show order details


 <p>Thank you. Your order has been received.</p>
        <p>Order Number: <b><?php echo $_GET['order_id'];?></b></p>

<p>Thank you. Your order has been received.</p>

<p>Order Number: <b><?php echo $_GET['order_id'];?></b></p>

Step-10: Create a page (error.php)


<p>Error. OOPs Someting went wrong!</p>
