Frequently Asked Questions
Here are some frequently asked questions about the gtag extension for Launch.
The Google Tag (formerly Google's Global Site Tag and also known as gtag.js) is a JavaScript tagging framework and API that allows you to send event data to Google Ads, Campaign Manager, Display & Video 360, Search Ads 360, and Google Analytics. This framework that allows a seamless integration between the Google products. It is important to note that gtag is not a tag manager, which might be confusing since the main
gtag.js library is served from www.googletagmanager.com. But rest assured, we're not advocating for you to load a tag manager within a tag manager! Nope! There are a few other gtag extensions that Adobe has created, but you only need to install the one from Acronym in order to install all of the products on your site. Adding other gtag extensions may cause unexpected results, and is not recommended.

Yes! The extension supports GA4. Simply use the account ID starting with
G- when adding a new account.The gtag.js library passes e-commerce data within custom data fields. Since Launch is data layer agnostic (meaning it does not have a set data layer format), it is ultimately up to you to create data element(s) that provide the data for the e-commerce fields.
You can find all of the relevant information on Google's Enhanced Ecommerce documentation. For reference though, you can pass the following custom data fields:
Custom Data Field | Format | Description |
items | An Array of Objects: [ { }, { }, { } ] | Each object should contain various properties about the item / product on the page |
promotions | An array of Objects: [ { }, { }, { } ] | Each object should contain the name and ID of the promotions from the page / event |
coupon | String | The name of the coupon code entered |
value | Number | This can be mapped within events natively, but for page views this should be the total value
of the items / products. |
checkout_step | Non-negative Integer | The step number of the checkout funnel the visitor is currently on |
checkout_option | String | An optional field that can provide more information about the current checkout step |
transaction_id | String | The unique ID for the purchase / transaction |
currency | String | The currency of the event's value |
tax | Non-negative Float | The amount of taxes collected, if applicable |
shipping | Non-negative Float | The amount of shipping fees collected, if applicable |
affiliation | String | The store or affiliation from which this transaction occurred |
Let's say you had the following data layer setup on your page:
window.dataLayer = {
"ecommerce": {
"purchase_id": "123abc",
"shipping": 20.00,
"taxes": 5.25
},
"products": [
{
"id": "prodA",
"name": "My awesome tshirt",
"price": 12.45,
"quantity": 5
},
{
"id": "prodB",
"name": "Foobar snacks",
"price": 5.32,
"quantity": 8
}
]
};
In Launch, You could setup a few data elements that referenced the
dataLayer.products, dataLayer.ecommerce.purchase_id, dataLayer.ecommerce.shipping, and dataLayer.ecommerce.taxes properties. From there, you can map the data elements in the custom data fields for the purchase event:
An example of a purchase event, setup with the e-commerce data layer properties mapped via data elements.
It's on our roadmap to explore making this easier for non-developers to implement, but since Launch is data layer agnostic, it likely won't be added in the near future.
You may see multiple instances of
https://www.googletagmanager.com/gtag/js in your network requests. Our extension only loads one for the initial account. Due to the way Google configured the Gtag library, each account will load their own library file. Requests that contain &cx=c are loaded by the main Gtag library and not our extension.The following items are planned in future releases:
- Better UI for GA4 handling, Universal Analytics (GA3) will be deprioritized given its sunset in 2023.
- Add the ability to prevent accounts from automatically running the
configcommand on a page. - Allow custom Gtag library URL and/or code input (for those with more strict IT policies).
- Add additional custom code injection points during the initialization phase.
- Add support for e-commerce fields without having to create a custom data element.
- Add support to globally disable an account in the extension configuration (instead of either disabling it in every rule or removing it).
