For this type of tracking, you must add code into your "thank you" or confirmation page. This would be the page that all customers are directed to after completing their order. Below is sample code which you should use as a starting template.

Within this code, you must dynamically insert the customer's transaction information from the respective order. We've added some dummy order information for your reference. Not all data is required, but all is recommended. A description of each field is available at the end of this article.

For best performance, place this code just before the </body> tag in your HTML.

Code

<!-- REFERSION TRACKING: BEGIN -->
<script src="//www.refersion.com/tracker/v3/pub_0123456789DEMO.js"></script>
<script>
_refersion(function(){

	_rfsn._addTrans({
		'order_id': '12345',
		'shipping': '11.90',
		'tax': '5.23',
		'discount': '2.32',
		'discount_code': 'TESTCOUPON',
		'currency_code': 'USD'
	});

	_rfsn._addCustomer({
		'first_name': 'Nancy',
		'last_name': 'Parker',
		'email': '[email protected]',
		'ip_address': '808.53.77.22'
	});

	_rfsn._addItem({
		'sku': 'DD23444',
		'quantity': '2',
		'price': '100'
	});

	_rfsn._addItem({
		'sku': 'XJ66778',
		'quantity': '3',
		'price': '50'
	});

	_rfsn._addItem({
		'sku': 'MP39592',
		'quantity': '2',
		'price': '1000'
	});

	_rfsn._sendConversion();

});
</script>

Another way to report orders to us is by creating a Webhook. Usually this option requires a greater amount of development work since you'll be "posting" order information to us directly from your server.

There are two requirements for this implementation:

1. Sending us a cart_id using a short JavaScript code on your "thank you" page so that we may reference any future Webhook reported to the session.
2. An HTTP POST of the actual order information from your server, which contains the previously reported cart_id.

The cart_id value

When we receive any Webhooks, we must associate it with a previously captured browser session. However, since Webhooks are reported from the server-side and not the browser-side, we can not access the relevant customer's session information. For this reason, we use the cart_id value as a common identifier that we can reference. We ask you to report a cart_id on your "thank you" page where we store session information and then a second time in the Webhook so that we may associate it with the aforementioned browser session from the JavaScript call.

The cart_id may be any string value up to 255 characters.

Reporting cart_id

Please copy/paste the following code into your "thank you" or confirmation page. This would be the page that all customers are directed to after completing their order.

Code

<!-- REFERSION TRACKING: BEGIN -->
<script src="//www.refersion.com/tracker/v3/pub_0123456789DEMO.js"></script>
<script>_refersion(function(){ _rfsn._addCart("YOUR-CART-ID"); });</script>
<!-- REFERSION TRACKING: END -->

You must replace "YOU-CART-ID" with the actual cart_id value. Please make sure to include the double quotes.

Posting the Webhook

Data must be reported as JSON string which contains the order data as well as the cart_id. You Refersion API keys (public and secret) should be sent in the header. Below is an example of the JSON that we are expecting.

{
	"cart_id": "DDXqfBngTWuX8N8Asqr2mY3RkmHCXdM7Vz6mdHkjwrEnN5zyRY",
	"order_id": "20150401102883",
	"shipping": 9.99,
	"tax": 0.57,
	"discount": 2.25,
	"discount_code": "HOLIDAY1",
	"currency_code": "USD",
	"customer":{
		"first_name": "John",
		"last_name": "Doe",
		"email": "[email protected]",
		"ip_address": "234.192.4.75"
	},
	"items": [
		{
			"price": 5.50,
			"quantity": 2,
			"sku": "PROD_A",
			"name": "Product A"
		},
		{
			"price": 10.00,
			"quantity": 1,
			"sku": "PROD_B",
			"name": "Product B"
		},
		{
			"price": 15.00,
			"quantity": 3,
			"sku": "PROD_C",
			"name": "Product C"
		}
	]
}

To deliver this data to us to you must send it via an HTTP POST. Below is example PHP code using cURL.

<?php

// The complete data that you are sending
$order_data = array(...); // Omitting data for demonstration

// Convert array into JSON
$json_data = json_encode($order_data);

// The URL that you are posting to
$url = 'https://inbound-webhooks.refersion.com/tracker/orders/paid';

// Start cURL
$curl = curl_init($url);

// Verify that our SSL is active (for added security)
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, TRUE);

// Send as a POST
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, 'POST');

// The JSON data that you have already compiled
curl_setopt($curl, CURLOPT_POSTFIELDS, $json_data);

// Return the response
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);

// Set headers to be JSON-friendly
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Content-Length: ' . strlen($json_data),
    'Refersion-Public-Key: YOUR-PUBLIC-KEY',
    'Refersion-Secret-Key: YOUR-SECRET-KEY')
);

// Seconds (30) before giving up
curl_setopt($curl, CURLOPT_TIMEOUT, 30);
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 30);

// Execute post, capture response (if any) and status code
$result = curl_exec($curl);
$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);

// Close connection
curl_close($curl);
