  • How to Integrate GA4 API in C# Website with Gmail Account Credentials and Fetch Analytics Data without Using Client Key?

    Hey, I’m currently working on a project where I need to create a website in C#. I’m trying to integrate GA4 and honestly, it’s a bit of a head-scratcher. I would like to build it so any Gmail account could connect to the GA4 API (just using the usual user id and password), then select their property account from a list and see their respective data, all this without having to use a specific client key. If anyone could lend me a hand or point me in the right direction, I’d be super grateful!

    Alright, lets break this down. You wanna connect to the GA4 API using a Gmail account, right? Sadly, that’s a no-go, mate. Google nipped this in the bud back in 2015. To get your mitts on private user data, you gotta use something called oauth2 which needs the user’s OK.

    Also, no go on not using a specific client key. Oauth2 needs your app to be registered and approved by Google to access private user data. When you’re asking for authorization, you’ll need your client id and client secret.

    As far as learning more, you could look into the Google Analytics Data v1 API. Hope this breaks things down for you a bit, good luck with the website!

    Given the nature of your project, this would involve using Google’s OAuth 2.0 service for authentication and authorization. Google provides useful developer guides on this subject on their website. A step-by-step process would be something like this:

    – Initiate an OAuth 2.0 flow from your application
    – Direct the user to Google’s OAuth 2.0 server to authenticate & authorize your application
    – Google’s server redirects back to your application (with an authorization code – single use) after user approval
    – Exchange this authorization code for an access token from Google’s server.

    This access token grants your application access to user’s GA4 data on their behalf. Note however that this will still require a Client ID and secret from Google Cloud Console for your application. It is significant to note that due to security concerns, direct use of user ids and passwords without such a client key isn’t advisable (or possible, as far as I know).

    For accessing GA4 data, you will likely want to utilize the Data API which provides access to report data in Google Analytics 4 properties. This describes all the ways to pull data reports from GA4 properties.

    Lastly, do remember that as this involves handling sensitive user data, be sure you’re in compliance with all relevant legal and privacy considerations (including Google’s user data policy when using OAuth 2.0). It would be advisable to seek legal counsel if you have concerns about handling this data in a legally compliant way. Good luck with your project!
