Conversion Tracking

Overview

Tradedoubler's tracking technology allows you to track and reward publisher activity in a way that suits you. You can:

• Track and award commission on an event, product category or individual product level.
• Control commission attribution and stop voucher code misuse with voucher code tracking.
• Send tracking data to Tradedoubler without any tracking tags or pixels on your website.
• Automate your transaction validation process (transaction approval and deletion).

All these features are supported by Tradedoubler's global performance tracking platform. We'll use latency load balancing technology to ensure traffic is routed through the best data centre from anywhere in the world.

Once tracked every transaction then passes through Tradedoubler's proprietary tracking validation process. Impressions, clicks, leads and sales are all screened by dozens of quality checks to confirm their validity. So you can be confident in the accuracy of transactions being reported.

1st party tracking

Tradedoubler is using 1st party data to attribute conversions for over 15 years. This attribution method is the most accurate way of connecting specific events on your website with their respective sources. Using our First Party Cookie Validation, that relies on the storage of a Tradedoubler Unique Identifier (TDUID) on the client domain level, all advertisers and the connected publishers will be able to see an immediate growth of their tracked conversions, thanks to the increased reliability of the tracking setup

Cookieless Tracking

Our cookieless tracking solution ensures that all online journeys are accurately tracked, even when a cookie is not present. This ensures that we are able to provide a complete, accurate and reliable picture of all online journeys leading up to a sale.

1. Accurate tracking across all internet connected devices, without the use of cookies.


2. Device fingerprint created without using personally identifiable information.


3. Automatically active across our publisher network.


4. Easy implementation for advertisers.

Cross Device Tracking

Tradedoubler's Cross Device Tracking allows you to track user activity (clicks, leads and sales) across their multiple devices. Using deterministic matching (first party data) Tradedoubler matches devices to a user and creates an anonymous profile. Benefits include:

1. Correct attribution of conversions to devices, publishers and marketing channels.


2. Track user activity across environment - desktop web, mobile web and in-app.


3. Accurate understanding of how your digital marketing budget is performing across devices and channels.


4. Privacy-compliant matching and tracking techniques that protect user data.

Transaction validation

Customers returning goods or cancelling orders? Automate your transaction validation now and save time and money. To suite your needs Tradedoubler offers different ways of automating this process:

• Use XML batch files
• Use API endpoints

Voucher Code Tracking

As well as providing a voucher code distribution system Tradedoubler also offers voucher code tracking - allowing you to report what codes are used for each transaction. This provides three powerful benefits:

1. Visibility in reports: Reported voucher codes are displayed alongside transactions in the standard reports. This enables advertisers and publisher to analyse the performance of specific codes. If you use exclusive codes for specific publishers, promotions, ad slots, etc. then you can now see their impact on conversion.


2. Control commission attribution: Exclusive voucher codes can be easily attributed to one or many specific publisher site IDs. When a transaction is reported together with a voucher code Tradedoubler's proprietary validation tests will check if the publishing generating the transaction was allowed to use the code. If not, the transaction can be invalidated or reassigned to the correct publisher. That means you no longer have to battle voucher code theft across your performance marketing.


3. Link offline to online: Linking a voucher code to a specific publisher site ID means we no longer need a click or impression to know who to assign transactions to. Without the need for a click or impression we are no longer tied to an internet-connected device so the exclusive voucher code can be used in print, radio, TV, etc. When the user completes the transaction online and advertiser reports it to Tradedoubler, the link will be made and the commission assigned to the correct publisher.

Tradedoubler also offers a voucher code distribution system. Check out Vouchers Open API for more information.

Extend transaction lifetime

Your program can be set up to use pending periods, meaning all transactions will remain 'pending' for a set period of time after they are tracked. The pending period typically reflects the advertiser's returns policy, allowing them to amend or deny transactions before they are invoiced. Examples include a user cancelling the order, returning part of the order or payment being rejected. In these scenarios the advertiser will need to amend or deny the transaction in Tradedoubler's system.

The standard pending functionality works on an event ID level, meaning the same pending period is applied to all transactions under an event ID. In some scenarios it is preferable to set the pending period on a transaction level instead. For example:

• Travel - It is typical to approve transactions once the user has completed their stay at the hotel, taken the flight, returned the hire car, etc. Users could be booking flights, hotels, holidays and car hire just hours in advance or for many months in the future.
• Insurance/Finance - Users are often required to honour their contract for a minimum amount of time before it is considered an approved transaction.
• Telecoms - Different mobile devices and contracts can become profitable for the advertiser at different times.

The validOn parameter in the tracking pixel allows you to enter the date when the transaction should become approved. You only need to tell Tradedoubler about transactions that need to be amended or denied before the Valid On date is reached. All other transactions will be automatically approved on the Valid On date.

Individual Product Information

The reportInfo parameter in the tracking pixel allows advertisers to report product data for each transaction. The standard implementation includes product ID, product name, product price and quantity purchased. This information is then visible for advertisers and publishers in the standard reports.

For the ability to award commission and set up promotional pricing on product level see the Product Level Tracking section.

Standard Set-up

Follow this step by step guide to quickly enable the most robust Tradedoubler conversion attribution on your website. Tracking and attribution is the core of our business, and we continue to invest in our tracking technology.

Tracking Library

Tradedoubler's Tracking library is a small and powerful JavaScript toolkit that is designed to help you implement our cutting-edge event attribution technology on your website. It should be executed unconditionally on all of you pages making it easy to manage and scale it to suit your needs. The toolkit does not track any action unless it is directly instructed by you, so it is safe to use in accordance with privacy considerations. The sole purpose of this tool is to let you manage your transaction attribution and get insights on which partners deliver quality traffic to your website.

Tracking Library features include:

1. Conditionally store Tradedoubler’s unique user ID
2. Store Tradedoubler’s Strictly Necessary ID to support consented traffic (i.e. cashback/reward partners)
3. Handle cookie consent and tracking consent
4. Track on-line events in real time
5. Accurately track events even without cookies
6. Unlock Tradedoublers automated tag management
7. Trigger server-to-server tags to your partners

Initialise the Tracking Library

To Initialise the Tracking Library place the script on all pages of your website. You will find an example script below. Your individual version might be slightly different as it is tailored to your specific needs, please follow the instructions provided by your Tradedoubler Support representative. The Library takes care of all your conversion tracking needs. It also contains a fallback logic built in to make sure you can always measure your events.

<script type="text/javascript">
/*THIS SCRIPT IS ONLY AN EXAMPLE*/
           (function(c,w,v){function getUrlParameter(e){var t=new RegExp("[\?&]"+e+"=([^&#]*)").exec(location.search);return null===t?"":decodeURIComponent(t[1].replace(/\+/g," "))}function setCookie(e,t){var r,n=w.location.host,a=n.substring(n.indexOf("."));(a.match(/\./g).length<2||".co"===a.substring(0,a.indexOf(".",1)))&&(a="."+n),r='domain='+a;var i=new Date,o=i.getTime()+31536e6;i.setTime(o);var c="expires="+i.toUTCString();v.cookie='e'+'='+'t'+';'+'c'+';'+'r'+';path=/;sameSite=none;Secure=true'}var tdclid_sn=getUrlParameter("tdclid_sn");tdclid_sn&&setCookie("tdclid_sn",tdclid_sn);var q='?org='+c.organization+'&prog='+c.programId;w.tdfallback=function(e){var t,r=v.getElementsByTagName("script")[0];(t=v.createElement("script")).src=e+q,r.parentNode.insertBefore(t,r)};
          (function(i,s,o,g,r,a,m){i['TDConversionObject']=r;i[r]=i[r]||function(){(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)})(window,document,'script', 'https://sdk.tradedoubler.com/trsdk'+q, 'tdconv'); tdconv('init',c);
          })({organization: '123456', programId: '654321', program: false, element: 'iframe'}, window, document);
/*THIS SCRIPT IS ONLY AN EXAMPLE*/
</script>
							

Trigger conversion events

When tracking events on your website you need to provide event attributes. Complete list of attributes is available here.

Example Sale tracking event with all attributes included:

<script type="text/javascript">
/*Define the event*/
var TDConversion = { 
        transactionId: '[ORDER_NUMBER]', 
        ordervalue: '[ORDER_VALUE]', 
        currency: '[CURRENCY]', 
        voucher: '[VOUCHER]', 
        event: 123456, 
        eventTime: '2024-04-22%2011:59:59',
        validOn: '2024-12-30',
        cdt: { 
            extId: '[SHA-256_EMAIL_ADDRESS_HASH]', 
            extType: 0 
        },   
        products: [
            {'id': 'ABC/101', 'name': 'Żółta łódź podwodna', 'price': '9.99', 'qty': '1'},
            {'id': 'ABC/102', 'name': 'Yellow submarine', 'price': '9.99', 'qty': '2'}
        ],
        reportInfo: 'f1=ProductID&f2=NameProduct&f3=1&f4=1' 
    }; 
/*Send the data to Tradedoubler*/
tdconv('track', 'sale', TDConversion);
tdfallback('{tradedoubler_provided_value}');
</script>
							

Example Lead tracking event with minimum attributes included:

<script type="text/javascript">
/*Define the event*/
var TDConversion = { 
        transactionId: '[ORDER_NUMBER]', 
        event: 123456
    }; 
/*Send the data to Tradedoubler*/
tdconv('track', 'sale', TDConversion);
tdfallback('{tradedoubler_provided_value}');
</script>
							

Available event attributes:

products: [
{'id': '101', 'name': 'Product-1', 'price': '0.99', 'qty': '1'},
{'id': '102', 'name': 'Product-2', 'price': '9.99', 'qty': '2'}
]
							

Manage Consent

To make sure the Tracking Library is aware of your user's consent you should use the following call.

<script type="text/javascript">
    tdconv('cookie-consent', true); 
</script>	

• localStorage variable “tdcookieconsent” is created with value “false”
• “tduid” first party cookie and localStorage variable shall not be stored
• tracking requests will not store any additional 1st or 3rd party cookies

Custom Tracking Integrations

We strongly recommend the easy set-up guide. Follow any of the instructions below only when directly instructed by your Tradedoubler support representative.

Pixel Tracking

Pixel tracking is the most common type of tracking as it is quick to implement and provides instant data for advertisers and publishers. It is our preferred tracking method and we would recommend it wherever possible. It consists of two elements:

1. Redirect page: All Tradedoubler traffic will pass through this page before directing the user onto the requested page on your site. This page will handle Tradedoubler's unique tracking identifier (TDUID) and cookie setting tasks.
2. Confirmation page: The tracking pixel (also known as the tracking or conversion tag) must be displayed on the confirmation page. This is the page immediately after the transaction has been completed (e.g. confirming the order has been placed).

Redirect Page

You can find redirect scripts in various programming languages in the Example redirect scripts section. This section explains what the script does and highlights any changes you may need to make.

The redirect page is a core part of Tradedoubler's tracking as it removes the reliance on third party cookies. The redirect page sets the data on your domain in a first party cookie. This provides a very secure tracking process without the risk on untracked sales caused by cookie blocking.

The redirect page is a simple script that you must host on your domain. We suggest naming the page redirect or td_redirect. When the page is live you must send the URL to your Tradedoubler contact so we can update the program's tracking settings.

All traffic will be sent to this page with two parameters in the URL:

1. TDUID: Tradedoubler's unique identifier. Used for matching impressions/cicks with leads/sales.
2. URL: This is the destination that the user/ad requested to be sent to.

You can also include custom parameters (e.g. site analytics information) on all links, which can be collected on the redirect page and used as you require. If you are using a third party tracking provider (e.g. DoubleClick or Atlas) you can pass the TDUID in a custom parameter so it can be inserted into the tracking pixel later. Speak to your Tradedoubler contact if this is needed.

The inbound link will look something like this:

http://www.domain.com/td_redirect?tduid=489edf2b468ca1b0367f8d0bbf6ab611&url=http://www.domain.com/prod?id=219

Storing the TDUID

The TDUID will be stored as follows:

1. Persistent cookie: Set to expire after one year from today's date (the cookie window will be managed from Tradedoubler's system). The cookie must be named TRADEDOUBLER.
2. Session variable: Set to expire once the session has ended. We suggest naming the variable TRADEDOUBLER for consistency.

Some examples of how to achieve this are:

PHP setcookie("TRADEDOUBLER", $tduid, time()+3600*24*365, "/", ".domain.com")

ASP Response.Cookies("TRADEDOUBLER").Domain = ".domain.com"

Redirecting the user

If there is a destination URL included in the inbound link the script will collect this and forward the user to the requested page. If the URL is empty then the user will be sent to your site's default URL.

The redirect script you receive from Tradedoubler will have the default URL set to http://www.domain.com. You must change this to your default landing page (normally your site homepage).

If your site requires URLs to be encoded please notify your Tradedoubler contact. They will change the program settings so that the URL parameter is UTF-8 encoded like so:

...url=http%3A//domain.com/prod%3Fid%3D219

Direct Linking

It is possible to handle these tasks without the use of a redirect page. Your Tradedoubler contact can change the program settings to send users direct to the requested URL (e.g. a specific product page).

If this option is implemented then you must use a script to handle the cookie and session variable setting on ALL pages on your site. This should be a standard module used on all page loads so that it is not missed when new pages are created.

To achieve this you can use the redirect page script and remove the section handling the redirect.

Confirmation Page

The confirmation page is the page directly after the payment has been processed. It will typically confirm to the user that the order has been placed. This page needs to contain Tradedoubler's tracking pixel in order for the order details to be tracked.

The tracking pixel should be placed as high on the confirmation page as possible to ensure it loads successfully. We suggest immediately after the opening <body> tag.

You can find scripts in various programming languages in the Example pixel tracking scripts section. They show how to collect the required values and construct the tracking pixel. Below are examples of how the final tracking pixel will look for leads and sales.

A standard sale tracking pixel looks like this:

<iframe src="https://tbs.tradedoubler.com/report?organization=12345&event=12345&orderNumber=12345&orderValue=10.99&currency=EUR&tduid=e0f15774d8d148963fd2df1bf9396d54&type=iframe&voucher=SALEXMAS2014&validOn=2015-01-30&checksum=v0444fb650f3d10e030c973f73bcacb9b51&extid=f660ab912ec121d1b1e928a0bb4bc61b15f5ad44d5efdc4e1c92a25e99b8e44a&exttype=1&reportInfo=f1%3DProdNr01%26f2%3DProdName1%26f3%3D100.00%26f4%3D2&event_time=2020-01-01%2023:59:59&cons=false" frameborder="0" width="1" height="1"></iframe>

A standard lead tracking pixel looks like this:

<iframe src="https://tbl.tradedoubler.com/report?organization=12345&event=12345&leadNumber=12345&tduid=e0f15774d8d148963fd2df1bf9396d54&extid=f660ab912ec121d1b1e928a0bb4bc61b15f5ad44d5efdc4e1c92a25e99b8e44a&exttype=1&type=iframe&checksum=v0444fb650f3d10e030c973f73bcacb9b51&event_time=2020-01-01%2023:59:59&cons=false" frameborder="0" width="1" height="1"></iframe>

Pixel parameters

The tracking pixel can contain the following parameters.

Testing the implementation

Every implementation needs to be tested to verify that the tracking is working correctly. Once you have implemented the redirect page and pixel tracking get in touch with your Tradedoubler contact, who will provide you with a test link.

Before each test make sure you clear your cookies and internet cache to ensure the test results are accurate.

Follow these steps for each test:

1. Clear your cookies and internet cache.
2. Click on the test link. You should be redirected to the default URL specified in the redirect page (usually your site homepage).
3. Perform a transaction (lead or sale).
4. You should end up on the confirmation page. Select 'view page source' (or your browser's equivalent).
5. Search for tbl.tradedoubler.com or tbs.tradedoubler.com (depending on whether you are a tracking a lead or sale). Copy the full URL (tracking pixel).
6. Log in to your Tradedoubler account and select Financial/Check Implementation from the menu system.
7. Follow the steps on this page to test the implementation.
   • Choose program: Choose which program you want to test.
   • Choose event type: Choose which event you want to test.
   • Enter trackback URL: Enter the URL (tracking pixel) you copied from your confirmation source code.
   • Tick the boxes to confirm you have completed the checks.

If the trackback is not correctly implemented you will get a detailed error message that indicates which part of the implementation is not functioning properly.

You can also check the 'lead/sale breakdown report' to confirm that the test tracked successfully. It can take between 10 and 45 minutes for transactions to appear in the reports.

Product Level Tracking

Product Level Tracking uses the same user journey described in the Pixel Tracking section, but the tracking pixel is different. This section covers the PLT tracking pixel only - you still need to implement the redirect page as described in the redirect page section and conduct testing as described in the testing section.

You can find scripts in various programming languages in the Example PLT scripts section. They show how to collect the required values and construct the tracking pixel. Below is an example of how the final tracking pixel will look.

This is an example PLT sales tracking pixel for an order consisting of one iPod Nano worth £100 and two iPhones worth £300 each:

<iframe src="https://tbs.tradedoubler.com/report?o(12345)event(51)ordnum(11821909)curr(GBP)chksum(v0477007e101263751dba5148752ac9eb9d)tduid(2ce09b3278da9e51434039b6687d4117)extid(f660ab912ec121d1b1e928a0bb4bc61b15f5ad44d5efdc4e1c92a25e99b8e44a)exttype(1)type(iframe)voucher(SALEXMAS2014)enc(3)basket(pr(i(AB453%2D435)n(Ipod%20Nano%202gb)gr(25)v(100)q(1))pr(i(AD455%2D425)n(IPhone%2016gb)gr(46)v(300)q(2)))event_time(2020-01-01%2023:59:59)cons(false)" frameborder="0" width="1" height="1"></iframe>

Pixel parameters

The tracking pixel can contain the following parameters:

Offline Tracking

Offline tracking uses the same user journey described in the Pixel Tracking section, but the transfer of conversion data to Tradedoubler is different. This section covers the post-conversion steps only - you still need to implement the redirect page as described in the redirect page section.

Storing the TDUID

The redirect page will have saved the TDUID in a session variable and cookie. When the transaction has taken place the TDUID must be collected from the session variable or cookie. Your Tradedoubler contact can provide code examples of how to achieve this.

Once the TDUID has been collected it needs to be stored in your database and linked to the transaction details. These will be collected and entered into a batch file in the next section.

Generating the XML file

On a regular basis you will need to generate a file with details of all conversions (leads and/or sales) and send it to Tradedoubler. The frequency of the file will differ depending on your business needs (i.e. daily, weekly or monthly), however we suggest you produce it as regularly as possible. This ensures there is regular data available for advertisers, publishers and Tradedoubler to analyse, review program performance and identify potential problems early.

The XML file must be saved using the following naming convention: standard_OrganizationId_SequenceId.xml. For example, standard_12345_1.xml would be used for the first file generated for organisation ID 12345.

The XML file will include the same parameters as outlined in the confirmation page section. There are four additional parameters for the batch file:

The format for sales is as follows:

Transferring the file to Tradedoubler

There are three ways of transferring the file to Tradedoubler:

1. Email to email@batch.tradedoubler.com
2. Post to an FTP/SFTP server

The choice of transfer method needs to be agreed with your Tradedoubler contact so they can implement the correct program settings.

Email

The batch file should be sent as an attachment on an email. The file should be attached directly and not within a compressed file (e.g. zip file).

FTP/SFTP

The file can be posted on your own FTP server, to which Tradedoubler has read access, or on Tradedoubler's FTP server. If using your own FTP server you will need to send your Tradedoubler contact the host, port, path, username and password. They also need to know how regularly the file will be updated and available for download.

If hosted on Tradedoubler's server you will need to tell your Tradedoubler contact the IP address of where the upload request will originate from (this is for security reasons).

<html>
<head></head>

	<p>Batch file <input type="file" name="files"><br><input type="submit" value="Send"> <input type="reset"></p>
	</form>
</body>
</html>

Testing the implementation

Every implementation needs to be tested to verify that the tracking is working correctly. Once you have implemented the redirect page and pixel tracking get in touch with your Tradedoubler contact, who will provide you with a test link.

Before each test make sure you clear your cookies and internet cache to ensure the test results are accurate.

Follow these steps for each test:

1. Clear your cookies and internet cache.
2. Click on the test link. You should be redirected to the default URL specified in the redirect page (usually your site homepage).
3. Perform a transaction (lead or sale). You should end up on the confirmation page.
4. Check that the data has been saved along with the order in your database.
5. Generate and transfer the batch file and notify your Tradedoubler contact together with the order number(s).

You can also check the 'lead/sale breakdown report' to confirm that the test tracked successfully. It can take between 10 and 45 minutes for transactions to appear in the reports.

Pending Transactions

All transactions are validated by Tradedoubler's proprietary tracking validation process. Once a transaction has passed these tests it is displayed in advertiser and publisher reports.

Programs can be set up to use pending periods, meaning all transactions will remain 'pending' for a set period of time after they are tracked and visible in reports. The pending period typically reflects the advertiser's returns policy, allowing them to amend or deny transactions before they are invoiced. Examples include a user cancelling the order, returning part of the order or payment being rejected.

Advertisers can automate the process of managing pending transaction validation using an XML batch file. Rather than validating transactions one at a time via the interface, advertisers can send a bulk update on a regular basis (i.e. daily, weekly or monthly).

Generating the XML file

The XML file must be saved using the following naming convention: pending_OrganizationId_SequenceId.xml. For example, pending_12345_1.xml would be used for the first file generated for organisation ID 12345.

You can choose to accept, deny or amend transactions in the batch file, as outlined in the following sections.

An explanation of each parameter can be found in the Pixel Tracking section.

Accepted transactions

To accept a transaction without any amendments use <status>A</status>:

<?xml version="1.0" encoding="UTF-8"?>
<tradeDoublerPending>
<checksum>ffd93f16876049265fbaef4da268dd0e</checksum>

		<eventId>5</eventId>
		<orderNumber>12345</orderNumber>
		<status>A</status>
							
	</transaction>
</transactions>
</tradeDoublerPending>

Denied transactions

To deny a transaction use <status>D</status>. You will also need to include a <reasonId>:

<?xml version="1.0" encoding="UTF-8"?>
<tradeDoublerPending>
<checksum>ffd93f16876049265fbaef4da268dd0e</checksum>

Amended transactions

You can amend a transaction's orderValue and reportInfo parameters when approving it if something has changed (e.g. some items were returned). To do so use <status>A</status> and include the updated ordervalue and reportInfo values:

<?xml version="1.0" encoding="UTF-8"?>
<tradeDoublerPending>
<checksum>ffd93f16876049265fbaef4da268dd0e</checksum>
<organizationId>12345</organizationId>
<sequenceNumber>1</sequenceNumber>
<numberOfTransactions>1</numberOfTransactions>
<transactions>
	<transaction>
		<eventId>5</eventId>
		<orderNumber>12345</orderNumber>
		<status>A</status>
		<orderValue>100.20</orderValue>
		<reportInfo>
			<item>
				<productNumber>B12D</productNumber>
				<productName>red shoes</productName>
				<price>100.20</price>
				<quantity>1</quantity>
			</item>
		</reportInfo>
	</transaction>
</transactions>
</tradeDoublerPending>

XML schemas

XSD files for the input format are available here:

Transferring the file to Tradedoubler

See here for instructions on how to transfer the file to Tradedoubler.

Testing the implementation

Every implementation needs to be tested to verify that the tracking is working correctly. Once you have implemented the pending batch file you will need to complete a test lead/sale so that you have a transaction to update.

If you are using real-time pixel tracking you can follow the testing steps here to complete a test lead/sale. If you are using offline tracking then follow the steps here.

Once you have a test transaction you need to generate the pending batch file and transfer it to Tradedoubler. You can check the 'lead/sale breakdown report' to confirm if the transaction status was updated successfully. It can take between 10 and 45 minutes for transactions updates to be processed.

You can also get in touch with your Tradedoubler contact to check if the test was successful.

Supporting Material

This section includes supporting material and example code for you to use during implementation. All code examples use random IDs and these must be replaced with your IDs, as supplied by Tradedoubler.

Please get in touch with your Tradedoubler contact if you need anything else.

Reason IDs

Below is a list of reason IDs that you can use when denying pending transactions:

Currency codes

Below is a list of supported currency codes:

Hash Function

Data privacy is extremely important so we request that all user IDs (extid) are hashed before being passed to Tradedoubler. We have chosen to use the SHA-256 function for its advanced security features.

Hashing is a one-way process meaning Tradedoubler or other partners can not decrypt the value and will never know the email address/user ID of the user.

Before passing the email address/user ID through the hash function you must ensure:

1. The value is all in lower case
2. There is no white space
3. Any encoding (e.g. special characters) is done using UTF-8

Many programming languages provide built-in library support for SHA-256 hashing. Here are some examples.

Java

The Apache Common Codec offers a built in SHA-256 function in the DigestUtils class as follows:

	public static String sha256Hex(final String data) {
	return Hex.encodeHexString(sha256(data));
	}
	

.NET

The .NET Framework offers a number of built in SHA-256 function in the SHA-256 Class of the System.Security.Cryptography namespace, including C#, C++ and VB.

Example Integration with Google Tag Manager

This section includes examples of how to integrate Tradedoubler's 1st Party tracking within Google Tag Manager. The first stage is capture Tradedoubler’s unique ID and set this value as a 1st party cookie on your website.

To do this in Google Tag Manager is easy:

Set 1st Party Cookie

	<script src="//hst.tradedoubler.com/file/47446/landingPageGTM_min.js"></script>
	<script>
		setTduid();
	</script>

Set Cookie value as User Defined Variable

Sales Tag

Select the variable you created earlier tduid and this will be automatically added to Tradedoubler Sales Tags.
