Funnel Setup for Custom Websites

For custom websites, the tracking script records visits, the RapidMetrics JavaScript SDK links each visitor to their email, and your server sends every sale and lead to RapidMetrics.

Step 1 - Install the Tracking Script

Go to Funnels and click the code icon on your Custom Website funnel. Copy the Tracking Script and paste it into the <head> of every page you want to track.

Step 2 - Identify Users

As soon as you know the visitor's email (a form, a login or your checkout), call:

RapidMetrics.identify({
  email: '[email protected]',
  first_name: 'John', // optional
  last_name: 'Doe'    // optional
});

Use the same email your server sends in Step 3. That is how a sale gets linked to the visit and the ad that brought the buyer.

Step 3 - Send Purchases From Your Server

When a payment succeeds, your server (or an automation tool like Zapier or Make) sends the sale to your funnel's webhook:

POST https://api.rapidmetrics.ai/v1/webhook/custom/YOUR_FUNNEL_ID
Content-Type: application/json
x-api-key: YOUR_API_KEY

{
  "event": "purchase",
  "email": "[email protected]",
  "amount": 97.00,
  "currency": "USD",
  "product_name": "My Course",
  "order_id": "ORD-123"
}

• YOUR_FUNNEL_ID is the ID after Funnel: in the first line of your tracking script.
• YOUR_API_KEY is under Integrations → Custom / API → Setup. Keep it on your server and never put it in a web page.

Step 4 - Send Leads From Your Server

Send each opt-in to the same URL with "event": "lead". Every lead you send counts in the funnel's F/E Leads for that day.

{
  "event": "lead",
  "email": "[email protected]",
  "first_name": "Jane"
}

To also send a Lead event to Facebook, call RapidMetrics.track('Lead'); in the browser. It only sends the Lead to Facebook. It does not add a lead in RapidMetrics.

All request fields, responses and error codes are in the RapidMetrics developer docs.
