# Heap – analytics and events tracking

Heap automatically captures all user interactions on your site, from the moment of installation forward.

## Installation

To start using the Heap integration, you must have installed the django-analytical package and have added the `analytical` application to `INSTALLED_APPS` in your project `settings.py` file. See Installation and configuration for details.

## Configuration

Before you can use the Heap integration, you must first get your Heap Tracker ID. If you don’t have a Heap account yet, sign up to get your Tracker ID.

### Setting the Tracker ID

Heap gives you a unique ID. You can find this ID on the Projects page of your Heap account. Set `HEAP_TRACKER_ID` in the project `settings.py` file:

    HEAP_TRACKER_ID = 'XXXXXXXX'

If you do not set an Tracker ID, the tracking code will not be rendered.

The tracking code will be added just before the closing head tag.

### Internal IP addresses

Usually you do not want to track clicks from your development or internal IP addresses. By default, if the tags detect that the client comes from any address in the `ANALYTICAL_INTERNAL_IPS` setting (which is `INTERNAL_IPS` by default,) the tracking code is commented out. See Identifying authenticated users for important information about detecting the visitor IP address.
