# Tracking Setup with Twitter / X

This guide explains how to set up tracking between FunnelFlux Pro and **Twitter / X**.

## Step 1: Add Twitter / X as a Traffic Source
1. Go to **Traffic Sources** > **New**
2. Search for "Twitter / X" in the template list
3. Select the **Twitter / X** template

The template configures the following tracking fields:

| Slot | Field Name | Token |
|------|------------|-------|
| external | twclid | `(empty)` |

**Cost type:** Cost Per Event/Click (no automatic cost token available — you may need to update costs manually)

## Step 2: Create Your Campaign URL
After creating the traffic source:
1. Build a funnel in the **Funnel Builder**
2. Click the traffic node and select **Twitter / X** as the traffic source
3. Copy the generated tracking link

Use this tracking link as the destination/campaign URL in Twitter / X. The URL includes all tracking field parameters, so Twitter / X will automatically replace the tokens with real values when a user clicks your ad.

## Step 3: Set Up Conversion Tracking
Twitter / X uses a **server-to-server (S2S) integration** via FunnelFlux's custom scenario system.

When you select the Twitter / X template, the **Conversion Tracking** tab is automatically configured with the **Twitter** custom scenario. This means conversion data is sent to Twitter / X through FunnelFlux's built-in integration rather than a simple postback URL.

To complete the setup, you need to configure the S2S integration in FunnelFlux's **Integrations** settings. See the S2S integration documentation for detailed instructions.

## Optional: Updating Costs
If cost tokens are not available or not accurate for your campaign type, you can manually update costs in FunnelFlux:
1. Go to **Update Costs** in FunnelFlux
2. Export your cost data from Twitter / X
3. Match the data by campaign ID and any relevant tracking fields
4. Import the cost data
