# Event data format

Customer data typically refers to the information related to individual customers or users that is collected and used for tracking their interactions and activities within a system or application. This data is crucial for various purposes, including analytics, personalization, and understanding user behavior. It may include details relevant information that helps in monitoring and analyzing user engagement.

# How to choose a Customer Id :

It is essential not to set the customer ID as "None" for multiple users, as it will lead Kursaha to group all their details and events under the same customer ID, assuming they are the same user. Additionally, avoid assigning customer IDs that may change, such as using email addresses. Remember that customer IDs are case-sensitive, so using different cases for the same ID will create separate profiles for the same customer in Kursaha's tracking.
