Developer Documentation & API Overview

REST API & Webhooks

Smartlead provides a well-documented REST API that allows developers to programmatically manage campaigns, leads, mailboxes, and sequences. Webhooks fire on key events (e.g., reply received, bounce detected, lead status changed) enabling real-time sync with external systems.

# Example: Add a lead to a campaign via API
curl -X POST https://server.smartlead.ai/api/v1/campaigns/{campaign_id}/leads \
  -H "Content-Type: application/json" \
  -d '{
    "api_key": "YOUR_API_KEY",
    "lead_list": [{"email": "prospect@company.com", "first_name": "Jane"}]
  }'

Key Integration Points

CRM Sync: Native and API-based integrations allow bi-directional sync of lead status, reply data, and deal stage with popular CRMs.
SmartAgents API: Trigger AI agent workflows (lead research, email personalization, CRM updates) programmatically or via no-code automation builders.
SmartDialer: Parallel dialing, call transcripts, objection tagging, and performance analytics are accessible via the dashboard and exportable for downstream analysis.
Email Verification API: Programmatically verify prospect emails before sending to reduce bounce rates.
