Hi
I have no coding background.. I am in marketing, trying to build an API for the unsampled data report in GA4 using Google Cloud Console.
I have done the following:
1- Created a service account in console,
2- downloaded the access key (Jason file)
3- enabled API
I have few questions here:
1- Now in GA4 I need to provide viewer access to my client email in the JASON file is that correct?
2- What would be the easiest way to do this? Do you have a JavaScript coding template that I can use.
3- Can I import the unsampled data using Looker or do I need to use BigQuery in this case?
Thank you so much
Hey @maintenance-candid12 
Welcome to the Postman Community! 
There are a lot of different tools and contexts (GA4, Google Cloud, Looker, BigQuery) here that are not familiar to many people, including myself.
Each of these tools with have their own public documentation which you can use to gain details about the structure of these requests and responses. Once you have those details, you can start to build a set of request which allows you to extract the data that you require.
This doesn’t sound like a small or trivial project - I would suggest reaching out to developers on your team to help pair with you, to get a POC together using these tools.
Member of this community can help you to a certain extent and help you with the Postman based parts of this but there isn’t a simple guide that could be shared here.
