@future-teacher-7046 Do I need to do any specific configuration in my react app for growthbook to track the user that views an experiment and later does the action that translates into data in my db? For example, if i want to know if the random user who viewed the pay button went ahead to make a payment in the db, is there any specific configuration I need to do using the sdk in order to track this user's payment in growth books

No special configuration. We use joins based on user ids when we query. So as long as you have a row in the experiments table and then another row somewhere else for the click event, and both have the same user ids (or anonymous IDs if they are logged out), we can report on the results.
