Virtusize Guide

# Top Page integration for Google Tag Manager (GTM)

This page will guide you through integrating Virtusize on the Top Page of your website using Google Tag Manager (GTM), which requires 5 steps:

1. Create a Custom HTML Tag

2. Adding the placeholders

We currently support one type of widgets:

  • Fitting Room Discovery

This widget can be placed anywhere on your page, but it is recommended to specify the placement using placeholders. Adding placeholders will allow you to freely change the design of your page without worrying about breaking Virtusize widgets in the future.

3. Inserting Virtusize values

This step allows you to define custom variables where you can set the values required for Virtusize to work properly.

4. Integrating the Virtusize script

This script is necessary for calling our central application responsible for displaying our widgets.

sample

# 2. Adding the placeholders

Please consult with your sales representative to determine the optimal positioning of the Virtusize tags.

If you are integrating the Virtusize Fitting Room Discovery (FRD) widget, please use the following JavaScript code by replacing frd-target-div with the target element where you want to place the Fitting Room Discovery widget:

<script>
  const targetDiv = document.querySelector(".frd-target-div");

  if (targetDiv) {
    targetDiv.append(Object.assign(document.createElement("div"), { className: "vs-placeholder-frd" }));
  }
</script>

Once you've finished. Choose a trigger for when the tag should fire.

# 3. Inserting Virtusize values

There are default variables from GTM that can be used on Virtusize integration. If the variable needed is not available, you can create a new custom variable by clicking on the variables menu and selecting New from the User-Defined Variables section.

sample

  1. Choose Data Layer Variable as the variable type.
  2. Give the variable a name (e.g., vs-user-id).
  3. In the Data Layer Variable Name field, enter the name of the data layer key that holds the value you want to capture.
  4. Save the variable.

# 4. Integrating the Virtusize script

Inside the custom HTML you can now setup the variables. You can use the default ones provided by GTM or make a new variable to fetch other data required. In the example below, vs-user-id variable was created and used inside the custom html.

<script type="text/javascript">
const vsObject = {
  storeName: "STORE_NAME",
  env: "ENVIRONMENT",
  deviceType: "DEVICE_TYPE",
  userId: "{{vs-user-id}}",
  page: "topPage"
};

(function() {
  window.vs = !window.hasOwnProperty("vs")
    ? vsObject
    : Object.assign(window.vs, vsObject);

  const { storeName, env, deviceType } = vsObject;
  const script = document.createElement("script");
  const firstScript = document.getElementsByTagName("script")[0];
  const protocol = document.location.protocol ? 'https' : 'http'

  Object.assign(script, {
    async: true,
    src: `${protocol}://integration.virtusize.com/${env}/${storeName}/${deviceType}.source.js`,
  });

  firstScript.parentNode.insertBefore(script, firstScript);
})();
</script>
value explanation
STORE_NAME This is the Store Name that you received from your sales representative.
ENVIRONMENT This can be either staging or production depending on what environment you are integrating on.
DEVICE_TYPE This can be either desktop or mobile depending on the device type the page is being accessed from. If your site is responsive (you serve the same resource to both desktop and mobile devices), please set this as desktop.
vs-user-id - Set empty string ('') when the user is not logged in.
- Set the user's ID (using a hash function such as MD5, SHA-1, etc...) when the user is logged in.

Once you've finished. Choose a trigger for when the tag should fire.
