Google Tag Gateway Setup via GTM – "Network Services API" Required?
Hello Everyone,
Hope you're having a good day.
I'm looking for some guidance on setting up Google Tag Gateway (GTG).
Background:
- Single GTM container across multiple domains.
- Server-side GTM is already set up.
- Each domain points to its own custom server endpoint using Google Cloud + Load Balancer (domain-wise configuration).
- Cloudflare is also in front of the setup.
I'm trying to enable Google Tag Gateway through GTM. Following Google's documentation, I went to GTM → Google Tag Gateway and attempted to link my Google Cloud project.
However, I receive the following error:
>The API it asks me to enable is the Network Services API.
Does the Network Services API need to be enabled before GTG can be configured via GTM with Google Cloud?
I couldn't find any mention of this prerequisite in the official Google documentation.
Has anyone encountered this before or successfully completed this setup? Any advice or confirmation would be greatly appreciated.
Thanks in advance!
