What Does “Send Lead via API” Mean?

It means transferring user data (lead) from your landing page or traffic source to a server endpoint.

This endpoint processes the data and routes it to the best destination.

Basic JSON Example

{
  "name": "John",
  "phone": "123456789",
  "email": "[email protected]",
  "geo": "US",
  "source": "Facebook"
}

This is the standard format used in most lead routing systems.

API Request Example (cURL)

curl -X POST https://yourdomain.com/api.php \
-H "Content-Type: application/json" \
-d '{"name":"John","phone":"123456789"}'

API Response Example

{
  "status": "accepted"
}

The API response indicates whether the lead was accepted or rejected by the system.

Step-by-Step Integration

1. Create API endpoint (api.php)
2. Accept POST request
3. Validate fields (name, phone)
4. Save lead in database
5. Send to routing engine
6. Return response (accepted/rejected)
