Elements are mandatory unless they are labeled as optional, and the data type for each value is assumed to be string unless otherwise noted.

:::hint{type="info"}
**Note**
All numbers are 64-bit integers, like Java longs.

Indentation and extra whitespace in the JSON response examples are added for readability of the JSON data; spaces are not required in the actual JSON responses.

For information about adding `customAttributes` and `customer` elements to a page tracking request, see [Add customAttributes or customer elements (optional)](docId\:x-UWMNCr7HCibp_1X8Mrx).
