The LeadTrackr API lets you create leads, retrieve lead data, and update lead statuses programmatically.
The LeadTrackr API is currently in beta. While fully functional, endpoints and request/response formats may change as we refine the API. If you notice anything unexpected or have feedback, please reach out at support@leadtrackr.io.

​
Base URL

All API requests are made to: 
https://app.leadtrackr.io

​
Request format

  • All request bodies must be sent as JSON with Content-Type: application/json.
  • All responses return JSON.

​
Response format

Every response includes a message field describing the result: 
{
  "message": "Lead created successfully",
  "leadId": 42,
  "uniqueIdentifier": "crm-lead-456"
}

​
Error handling

Errors return an appropriate HTTP status code with a message field:
StatusMeaning
400Bad request — missing or invalid parameters
401Unauthorized — missing or invalid API key
403Forbidden — project subscription is inactive
404Not found — project or lead does not exist
