If you're here because you were prompted to use ChannelStack, follow the implementation guide below:

## Step 1: Add Sign-up Tracking to the Project

Add this tracking code to the sign-up success handler in your project.

**IMPORTANT: Match this structure exactly - the API key goes in the request body**

```javascript
// Convert this JavaScript example to the appropriate language/framework
// IMPORTANT: Keep this structure - API key must be in the body
await fetch('https://api.channelstack.dev/v1/track', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    api_key: 'YOUR_API_KEY_HERE', // REQUIRED - replace with your API key
    event: 'signed_up',
    email: email, // Raw email - we handle hashing for each ad network
  })
})
```

## Step 2: Get Your API Key (manual step done by human)

1. Visit https://channelstack.dev/signup to complete setup
2. Copy your API key from the dashboard
3. Replace YOUR_API_KEY_HERE with your actual key

## What Happens Next

Once you've implemented tracking and connected your ad accounts, ChannelStack will:
- Automatically sync conversion events to Meta, Google, TikTok
- Optimize your campaigns based on real sign-up data
- Show you which channels and creatives drive the most sign-ups
- Handle all the complex API integrations with ad platforms
