Instantly

Access the Instantly API v2 with managed authentication. Manage cold email campaigns, leads, sending accounts, and view analytics.

Quick Start

# List campaigns
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/instantly/api/v2/campaigns?limit=10')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Base URL

https://gateway.maton.ai/instantly/{native-api-path}

Replace {native-api-path} with the actual Instantly API endpoint path. The gateway proxies requests to api.instantly.ai and automatically injects your API key.

Authentication

All requests require the Maton API key in the Authorization header:

Authorization: Bearer $MATON_API_KEY

Environment Variable: Set your API key as MATON_API_KEY:

export MATON_API_KEY="YOUR_API_KEY"

Getting Your API Key

1. Sign in or create an account at maton.ai
2. Go to maton.ai/settings
3. Copy your API key
