Get started

1. • Download the contents of dist/, choosing between a regular or minified version of the script.
   • Alternatively, pull the package from npm, choosing between a regular or minified version of the script within the created modules directory.

2. Include this on the post-payment/order-success page of your web project / e-commerce store.

3. See the example usages section below in order to choose your preferred way to begin tracking your UNiDAYS Offer Redemptions.

Note: Only transactions associated with UNiDAYS Offers should be tracked to the UNiDAYS API.

Parameters

A description of what information is required to create a UNiDAYS Offer Redemption event.

Mandatory

Parameter	Description	Data Type	Example
partnerId	Your partnerId as provided by UNiDAYS.	base64-encoded guid	XaxptFh0sK8Co6pI==
transactionId	The unique ID for the transaction in your system	string	order123
code	The UNiDAYS Offer Code redeemed in the transaction	string	UNI-C4RLB45KN

Optional

Parameter	Description	Data Type	Example
timestamp	A timestamp denoting when the transaction occurred	string (unix timestamp)	1577836800000

Note: If you have a Date object available for when the transaction occured, a UNIX timestamp can be obtained as follows: var unixTimestamp = myDateObject.getTime();. Alternatively, if you wish to obtain a UNIX timestamp of the current time, you can use: var unixTimestamp = Date.now();.

Example usages

Create script URL

This function should be used if you intend to make the request to the UNiDAYS API within a <script> element, or by using your own client. Using this function correctly will return a complete URL which can be used to track Offer Redemption events with UNiDAYS.

Using the createScriptUrl() function

The function to get the URL to make a client-to-server request with is .createScriptUrl(). To implement this function, you first need to ensure that you have access to all required transaction information.

Once you have access to this transaction information, create a UnidaysOfferTracking object, providing the mandatory parameters as arguments.

e.g.

var unidays = new UnidaysOfferTracking(partnerId, transactionId, code);

There are two approaches to creating a script URL - with or without a timestamp denoting when the transaction occurred.

To specify your own timestamp, simply include your UNIX timestamp as an argument for the function call.

e.g.

var url = unidays.createScriptUrl(timestamp);

To let the UNiDAYS helper-library generate a timestamp for you, simply omit any arguments in the function call.

e.g.

var url = unidays.createScriptUrl();

Full usage example

<script type='text/javascript' src='unidays-offer-tracking.js'></script>

<script type='text/javascript'>
    (function (window) {
        // UNiDAYS will provide your partnerId.
        var partnerId = '0LTio6iVNaKj861RM9azJQ==';

        // These must be based on the real values of the transaction.
        var transactionId = 'Order123';
        var code = 'ABC123';

        // Create a reference to the UnidaysOfferTracking object, passing in your partnerId, transactionId and code.
        var unidays = new UnidaysOfferTracking(partnerId, transactionId, code);

        // Get the UNIX timestamp for the date of the transaction. In this case, it is the current time.
        var timestamp = Date.now();

        // Call the createScriptUrl function to obtain a URL.
        var url = unidays.createScriptUrl(timestamp);

        // You now have a URL which can be used within a <script> element to call the UNiDAYS API.
    }(window));
</script>

Tracking script request

This function should be used if you would prefer for the UNiDAYS helper-library to track your Offer Redemption events for you. Using this function correctly will build the Offer Redemption event and asychronously call the UNiDAYS API to track the event.

Using the trackingScriptRequest() function

The method to call the API with a client-script request is trackingScriptRequest(). To implement this function, you first need to ensure that you have access to all required transaction information.

Once you have access to this transaction information, create a UnidaysOfferTracking object, providing the mandatory parameters as arguments.

e.g.

var unidays = new UnidaysOfferTracking(partnerId, transactionId, code);

There are two approaches to performation a request to the API - with or without a timestamp denoting when the transaction occurred.

To specify your own timestamp, simply include your UNIX timestamp as an argument for the function call.

e.g.

unidays.trackingScriptRequest(timestamp);

To let the UNiDAYS helper-library generate a timestamp for you, simply omit any arguments in the function call.

e.g.

unidays.trackingScriptRequest();

Full usage example

<script type='text/javascript' src='unidays-offer-tracking.js'></script>

<script type='text/javascript'>
    (function (window) {
        // UNiDAYS will provide your partnerId.
        var partnerId = '0LTio6iVNaKj861RM9azJQ==';

        // These must be based on the real values of the transaction.
        var transactionId = 'Order123';
        var code = 'ABC123';

        // Create a reference to the UnidaysOfferTracking object, passing in your partnerId, transactionId and code.
        var unidays = new UnidaysOfferTracking(partnerId, transactionId, code);

        //get the UNIX timestamp for the date of the transaction. In this case, it is the current time
        var timestamp = Date.now();

        // Call the trackingScriptRequest function.
        // The function will build and perform the request to the API asychronously within a script element.
        unidays.trackingScriptRequest(timestamp);
    }(window));
</script>

CDN and tag managers

This section describes how to use the UNiDAYS CDN to pull in the helper-library into your project/application, as an alternative to installing it. This includes an example of implementation with a tag manager (such as Google Tag Manager).

Note: We have included the SHA384 in the example below; file integrity is guaranteed, so you can be assured that you are always pulling in the official UNiDAYS JavaScript helper.

Using the helper-library

The method to call the API with a client-script request is trackingScriptRequest(). To implement this function, you first need to ensure that you have access to all required transaction information. In Google Tag Manager, for example, all of the required transaction information should be already available within the Data Layer for your online store. If any required information is not already available within the Data Layer for your online store, please contact your Development team and ensure this data is added.

Once you have access to this transaction information, create a UnidaysOfferTracking object, providing the mandatory parameters as arguments.

e.g.

var unidays = new UnidaysOfferTracking(partnerId, transactionId, code);

There are two approaches to performation a request to the API - with or without a timestamp denoting when the transaction occurred.

To specify your own timestamp, simply include your UNIX timestamp as an argument for the function call.

e.g.

unidays.trackingScriptRequest(timestamp);

To let the UNiDAYS helper-library generate a timestamp for you, simply omit any arguments in the function call.

e.g.

unidays.trackingScriptRequest();

Full usage example

<script src="https://cdn.unidays.world/unidays-offer-tracking.min.js"
    integrity="sha384-JEmfhKKRbcaBRGEgxbUtzA7pyWctEsPcVdw6QxjbVzmYEYtZsrh4hFRzosin018y"
    crossorigin="anonymous"></script>

<script type='text/javascript'>
    (function (window) {
        // UNiDAYS will provide your partnerId and signingKey.
        var partnerId = '0LTio6iVNaKj861RM9azJQ==';

        // These must be based on the real values of the transaction. (e.g. For Google Tag Manager, please reference your Data Layer)
        var transactionId = 'Order123';
        var code = 'ABC123';

        // Create a reference to the UnidaysOfferTracking object, passing in your partnerId, transactionId and code.
        var unidays = new UnidaysOfferTracking(partnerId, transactionId, code);

        //get the UNIX timestamp for the date of the transaction. In this case, it is the current time
        var timestamp = Date.now()

        // Call the trackingScriptRequest method. The method will build the request and perform it to our API within a script element.
        unidays.trackingScriptRequest(timestamp);
    }(window));
</script>

Notes:

• Most Tag Manangers (such as Google Tag Manager) requires you to reference Data Layer / User-Defined variables using {{This Syntax}} or something similar. If you are unsure, please contact your Development team associated with the Tag Manager platform you use.

• If your Tag Manager or CMS does not support the integrity attribute within <script> elements, simply remove the integrity and crossorigin attributes.

e.g.

<script src="https://cdn.unidays.world/unidays-offer-tracking.min.js"></script>
