# Identify Customers

A User is automatically created in Growlytics platrorm when user opens the app first time.

Initially, there are very few properties captured for User Profile like city, country, device info etc. Depending on your product purpose, You can add more information to user profile with `Analytics.identify()`  method. 

There are two ways you can do this 

1. If your customer has logged in with your system's user id, then you can pass customer's id which is in your system. This will help you keeping unified profile across web, mobile and other platforms. An example is given below.

   ```java
   // Prepare Attributes
   Map<String, Object> userAttributes = new HashMap<>();
   attributes.put("has_subscribed", true);
   attributes.put("total_cart_visits", 12);

   // Put them in growlytics user profile
   Analytics.getInstance(this).identify(userAttributes);
   ```
2. Another way, if user has not logged in yet but you still want to keep information as anonymous user, you can do that as well. An example is given below.

   ```java
   // Prepare Attributes
   Map<String, Object> userAttributes = new HashMap<>();
   attributes.put("has_subscribed", true);
   attributes.put("total_cart_visits", 12);

   // Put them in growlytics user profile
   Analytics.getInstance(this).identify(userAttributes);
   ```
