I am looking to see how we can allow a user to connect with their Google Analytic’s User ID and connect with our app and we can get the information from their account.
I am looking forward to some articles or any library thats build around the same.
I will be using PHP and MySQL. Do you suggest any other Database than MySQL ?
You can start with a database to keep things simple and since you are not looking to store too much of historical data. The link below should get you started with all the required libraries and documentation.
