How to Send Leads via API: Complete Guide for Beginners

Sending leads via API is the foundation of any modern lead generation system.

If you want automation, scalability, and profit — this is where everything starts.

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.

Step-by-Step Integration

1. Create API endpoint (api.php)
2. Accept POST request
3. Validate fields (name, phone)

5. Send to routing engine
6. Return response (accepted/rejected)
