### Retrieving Your Facebook Pixel ID

To set up the **Facebook Conversion API** in Weberlo, you first need your **Pixel ID**. Follow these steps to retrieve it:

1. Go to **Facebook Events Manager**.
2. Copy the **Pixel ID** from the pixel section.
3. Paste the **Pixel ID** into Weberlo’s **Facebook Conversion API Integration** settings.

### How the Facebook Conversion API Works

Unlike the **Facebook Pixel**, which tracks browser events, Weberlo’s **Conversion API** only sends **conversion events** to Facebook, specifically:

- **New Leads** – When a visitor submits a form.
- **New Purchases** – When a customer completes an order.

Weberlo **does not send Page View events** through the Conversion API.

You still need the **Facebook Pixel** on all pages to track **Page View events**.

Make sure no other sources are sending conversion events to **avoid duplicate events**.

### Activating Custom Conversions

Weberlo provides an option to send custom conversion events:

- **WeberloLead** (for new leads)
- **WeberloPurchase** (for purchases)

**Test Purchase Required**: Facebook requires at least one test purchase before you can create an **adset optimized for custom conversions**.

**Use Case**: If you already have an existing **Conversion API setup** but want to add Weberlo, using **custom conversions** prevents duplicate events.

**Optimizing Ads**: Once enough data is collected from **custom conversions**, you can use them to optimize ad performance and lower your CPA.

### Monitoring Event Match Quality

You can view all events sent to Facebook and their attributes in **Facebook Events Manager**. Key attributes include:

- **fbc** (Facebook Click ID)
- **fbp** (Facebook Browser ID)

These attributes improve **event match quality**, increasing the accuracy of Facebook’s attribution. Always monitor these values to ensure they are being sent correctly by Weberlo.

By setting up the **Facebook Conversion API** properly, you can enhance tracking accuracy, reduce wasted ad spend, and improve campaign performance.
