There are a lot of challenges in the GTM preview interface - many have likely noticed areas that could be improved. Data can often be difficult to read, and navigating the GTM preview can become cumbersome in large containers with numerous active tags. That's where browser extensions help - they make data clearer and navigation easier.

That's why the Stape team made a simple Chrome extension to improve the GTM preview. The whole GTM team uses it, so we know it will help many people.

What is Stape GTM Helper?

Stape GTM Helper is a free Chrome extension designed to improve the debugging experience in Google Tag Manager preview mode. The tool provides multiple features for both web and server GTM containers. With this extension, you can easily navigate fired tags, quickly identify failed ones, focus only on the tags you’re testing, and take advantage of other features, which we'll explore in detail below.

Who can benefit from Stape GTM Helper?

Stape GTM Helper will be helpful for anyone configuring data tracking using GTM. It can be used by data tracking specialists, data analysts, freelancers, or agencies that need a convenient tool to simplify the debugging process.

Stape GTM Helper has the following benefits:

  • Targeted tag testing. Filter and focus on the tags you need to test right now. Especially helpful if you have multiple entities in your GTM container.
  • Easy tag status identification. If you have multiple tags in a GTM container, it is crucial to navigate through them during the debugging process to figure out which tags fired and what failed. Stape GTM Helper adds color coding to the most popular tags and highlights the status.
  • Readability of request parameters. With Stape's extension activated, JSON incoming and outgoing requests, as well as the Request URL, are getting structured and easy to read. The feature will be helpful for sGTM users who need to view incoming/outgoing requests.
  • Clear consent status in sGTM. The consent status can be viewed only in the request parameters in server GTM debugging. The Stape GTM Chrome extension displays the four main consent statuses in the server preview.

Stape GTM Helper features and use cases

1. Entities filter

If you have multiple entities in your container and would like to test some of them, you can filter out only the necessary ones for convenient debugging.

The feature is available for both web and server GTM containers and can be used in Preview mode.

2. JSON formatter

4. Tag type coloring

This feature adds color coding and the platform's logo for the most popular tags (Meta, GA4, Google Ads, Microsoft, etc.). It works on both web and server preview, making it easier to navigate through triggered tags when there are many in the container.

Here's an example of what you get without the extension:

5. Tag status coloring

It helps track tags in Failed status or requests with status 4xx or 5xx. It works in the server and the web preview.

Here's an example of what you get without the extension:

When using Google Consent Mode in a server preview, the consent status can only be checked by examining the parameters of the incoming request. This complicates debugging, particularly if you suspect that some tags aren’t firing correctly due to consent issues.

The free Stape GTM extension for Chrome addresses this by adding the four main consent statuses to the server preview. It works by checking the 'gcs' parameter in GA4 requests. The extension shows the consent type and its status (granted or denied).

Here's an example of what you get with the extension:

Takeaway

The free Stape GTM Helper includes an Entities filter, a Request URL format, and a JSON format. The Entities filter allows you to filter certain tags for easier debugging. The URL format enhances the readability of queried parameters in URL requests, while the JSON formatter makes incoming and outgoing JSON requests easier to read. Combined with color-coded tag statuses and types, these features simplify debugging and improve the overall experience when working with sGTM.

You don't even have to create a Stape account to use the Stape GTM Helper. We'd love to hear your ideas and challenges that the Stape extension can help solve.
