# Pixel Setup in Facebook Business Manager

Before you can configure the Facebook Conversion API (CAPI) with JENTIS, you need to prepare your Pixel in **Facebook Business Manager**. This setup defines which data source JENTIS will send events to.

### Create a New Pixel (Optional but Recommended)

If you want to compare your **legacy tracking setup** with the new JENTIS architecture, create a **second pixel**:

1. Log in to [Facebook Business Manager](https://business.facebook.com/).
2. Navigate to **Events Manager → Connect Data Sources → Web**.
3. Select **Conversions API + Web Pixel**.
4. Give your pixel a descriptive name (e.g., *JENTIS Test Pixel*).

You will now receive a **new Pixel ID**. This allows you to:

* Keep legacy tracking untouched.
* Send new events via JENTIS to a clean data source.
* Compare results side by side.

### Use an Existing Pixel

Alternatively, you can connect JENTIS to an **existing Pixel**:

* JENTIS can send **both frontend (Pixel)** and **server-side (CAPI)** events into the same data source.
* Events from JENTIS will appear alongside existing events.
* To avoid **duplicate events**, either:
  * Disable the legacy tracking when you go live with JENTIS, or
  * Use Facebook’s deduplication parameters.

### Parallel Tracking Options

* **New Pixel** → Clean separation between legacy and JENTIS events. Useful for testing.
* **Existing Pixel** → Direct continuation of tracking within the same data source. Requires deduplication.

👉 Once your Pixel (new or existing) is set up, copy the **Pixel ID**. You will need this value when configuring your JENTIS Tool later.
