Endpoint Alias: You can also use /api/v1/records instead of /api/v1/leads. Both endpoints are functionally identical - use whichever naming convention fits your integration.

​
Lead Import Modes

The API supports two lead import patterns depending on your data availability:

Standard Mode

Phone number known at import timeProvide phoneNumber directly. The system will call this number when the lead is processed.Best for: CRM exports, contact lists, manual imports

Prefetch Mode

Phone number fetched just-in-timeProvide externalId only. The phone number is fetched from your CRM via a predial function before each call.Best for: CRM integrations where phone numbers change frequently or require real-time validation
At least one of phoneNumber or externalId is required. You can provide both if you want to track the external reference alongside the phone number.

Examples

Phone number provided at import time:
curl -X POST https://YOUR_DEPLOYMENT.lupitor.com/api/v1/leads \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "campaignId": "YOUR_CAMPAIGN_ID",
    "phoneNumber": "+15555551234",
    "externalId": "CRM_12345",
    "metadata": {
      "name": "John Doe",
      "company": "Acme Corp"
    },
    "priority": 10
  }'

  "success": true,
  "data": {
    "leadId": "jh7abc123xyz"
  },
  "error": null
}

​
Notes

Prefetch Mode Requirements: To use prefetch mode (externalId only), your campaign must have a predial function configured. Contact support to set this up.
Duplicate Prevention: Leads are deduplicated by externalId first, then by phoneNumber. If a lead with the same identifier already exists in the campaign, the request will fail.
Scheduling: If you don’t provide scheduledFor, the lead will be called as soon as possible based on business hours and priority.
Phone Format: When providing a phone number, it must be in E.164 format (+ and country code). Example: +15555551234
