To get the Google Analytics User ID variable, you can use the following methods:
- Use the User ID feature in Google Analytics: You can enable the User ID feature in Google Analytics and set it up to collect a unique User ID for each user. This User ID can be passed along with the other hit data, and can be used to analyze user behavior across devices and sessions.
- Use the Google Tag Manager: You can use the Google Tag Manager to set up a variable that captures the User ID. To do this, you need to create a variable in the Google Tag Manager that captures the User ID, and then use this variable in your Google Analytics tracking code.
- Use the Google Analytics API: You can use the Google Analytics API to fetch the User ID data and pass it to the GA script.
You need to have a User ID set-up in your Google Analytics to be able to fetch it.
It’s important to note that the User ID must be a persistent, non-personally identifiable string that represents the user. It should also be kept secure and not shared with unauthorized parties.
You should consult the Google Analytics documentation for more detailed information on how to set up the User ID variable and how to use it to analyze user behavior.
