 Every time you make an identify call with userId included:
 1.	Rehook verifies that the userId exists.

+2.	If the userId does not exist, Rehook adds the user as a Customer to the Rehook database and matches user properties with the Segment `traits` sent in the identify call payload.
 3.	If the userId exists, Rehook updates the user properties for the Customer against the Segment `traits` sent in the identify call payload.
+4.  If referral_code is unique, Rehook updates the user properties in its database.
 
 All the [special traits](/docs/connections/spec/identify#traits) recognized by Segment are translated and matched with the Rehook user properties for a Customer. These fields are automatically created or mapped for a Customer in Rehook and are available for personalization and advance segmentation.

 ### Track
 
 Take a look at the [Track method documentation](/docs/connections/spec/track) to learn about what it does. An example call looks like:
 
+#### Example 1:
 ```js
 analytics.track('Product Viewed', {
-  userId: "97980cfea0067",
-  product_id: '507f1f77bcf86cd799439011',
+  userId: "userId12345",
+  product_id: '507f1f779439011',
   name: 'Monopoly: 3rd Edition',
   price: 18.99,
   url: 'https://www.example.com/product/path',
   image_url: 'https://www.example.com/product/path.jpg'
 });
 ```
+
+#### Example 2:
+```js
+analytics.track('signup', {
+  userId: "userId12345",
+  referral_code: 'ERTYUS'
+});
+```
+
 Segment sends `Track` calls to Rehook as a Custom Event. When you call the track, Segment sends the event to Rehook with the event name and all properties that you specified.
 
-Be sure if you send an Identify or Track call without userId, the call will be dropped.
