I have implemented server-side tagging in in Google Tag Manager (GTM), but I'm sending HTTP requests directly from my backend code, rather than using JavaScript on the frontend (as many other developers). Since, the conversion tracking cookies set by Meta and Google aren't automatically sent when sending a HTTP request from my backend code, I am getting the _fbp and _fbc cookie values from the context and sending them as a "ep.x-fb-ck-fbp" and "ep.x-fb-ck-fbc" to the GTM server container, which allows me to track Facebook ads conversions successfully.

I am now looking to replicate this process for Google Ads. I understand that for Google Ads conversion tracking, the GCLID is a parameter that sets the _gcl_aw cookie which I should use to track conversion. However, I am not certain how to send this cookie value in the Http request that I'm sending from my server to the GTM server container.

In other words, if I'm sending the Meta's _fbc cookie value as a "ep.x-fb-ck-fbc" parameter, how should I send the Google's _gcl_aw and _gcl_au cookies.

I am a Facebook ads expert and i've been using the same pixel across mutiple ad accounts for my Roofing clients and I am looking to do the same thing with Google, I am not much knowlegable about google ads but is it possible that we use the same pixel(or GTM) across different ad accounts? The goal is to track the conversion data across different ad accounts which will ultimately help us to drive lower CPL. I hope i can do that. What is your opinion?

I tried Fb ads and i used the same pixel codes and conversion APIs to track the progress using the same pixel data and I am looking to do the same thing with google but i don't know how can i do it

I have a website hosted in AWS with a NodeJS backend.

I have Google Ads conversion events being sent from the frontend using gtag.js, but I noticed missing events and a lot of duplication (even if I use transaction IDs with my events)

I had similar issues with Facebook Pixel and was able to resolve the problem by sending simple vanilla http calls from my backend server.

Is it possible to do the same with Google Ads? I have not been able to find any documentation for server side APIs for Javascript. This documentation here seems promising, but no Javascript SDK exists. That's is why I would like to know what vanilla http calls to make.

I have seen documentation about GTM server side, but it seems I need to host a GTM container (server?) which I would prefer not to have to. Unless I misunderstood what hosting a GTM container means in the context of a AWS cloud solution.
