Limits and quotas for implementing web pages with Google Tag Manager

[juan06]

Hi,

We are currently implementing Google Tag Manager to track events on our website. We are looking at what the limits and quotas are for triggered tags or requests and triggers per day or second, however the only thing we saw is this regarding the REST API accessing the Tag Manager configuration data of Google and not to the API for web pages. We couldn't find documentation for this specific API, so we need your help understanding the limits of using Google Tag Manager when using events with the container.

Thanks.

Hi @juan06 

Talking about the limitation of GTM. Yes we do have limitation:

 there actually is a limit to the container size for Google Tag Manager, which is 200KB. If you run into this issue, the solutions are to optimize your tags with variables, lookup tables, and custom JavaScript to help consolidate tags. Through my experience of dealing with Google Tag Manager, I would have to say your best bet is to stay under 100-150 tags, as this was the closest we got until finding a number that was over the limit.

Also, 

Google by now supports server-side tag management. While SSGTM is not a Rest Api in any formal sense, you can send data there via an http endpoint.

1. If by the REST API you mean the Google Tag Manager API then no, this is for GTM configuration only.

GTM for web pages is not run on the server in any case - it bundles the configured tags into a JavaScript function that is evaluated and executed in the client, so there is nothing you could push the data to. And while it is vaguely possible you could reverse engineer the network calls from the Mobile SDK (mobile GTM is pretty much a different product with the same name) there is no supported API outside the platform specific SDKs.

1. GTM (for web) can evaluate everything that can be retrieved via JavaScript. So browser yes (via the navigator object), but no IP addresses, no http headers etc.

Hope this helps!
