# Instantly

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

## Quick Start

```bash
# 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`:

```bash
export MATON_API_KEY="YOUR_API_KEY"
```

### Getting Your API Key

1. Sign in or create an account at [maton.ai](https://maton.ai)
2. Go to [maton.ai/settings](https://maton.ai/settings)
3. Copy your API key

## Connection Management

Manage your Instantly connections at `https://ctrl.maton.ai`.

### List Connections

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=instantly&status=ACTIVE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Create Connection

```bash
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'instantly'}).encode()
req = urllib.request.Request('https://ctrl.maton.ai/connections', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Get Connection

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

**Response:**
```json
{
  "connection": {
    "connection_id": "e4dca622-b9cf-4ed6-b52e-fa681345f5ac",
    "status": "ACTIVE",
    "creation_time": "2026-02-11T22:19:35.798712Z",
    "last_updated_time": "2026-02-11T22:20:15.702846Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "instantly",
    "metadata": {}
  }
}
```

Open the returned `url` in a browser to complete authorization.

### Delete Connection

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}', method='DELETE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Specifying Connection

If you have multiple Instantly connections, specify which one to use with the `Maton-Connection` header:

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/instantly/api/v2/campaigns')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', 'e4dca622-b9cf-4ed6-b52e-fa681345f5ac')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

If omitted, the gateway uses the default (oldest) active connection.

## Pagination

Instantly uses cursor-based pagination with `limit` and `starting_after`:

```

Response includes pagination info:

```json
{
  "items": [...],
  "next_starting_after": "cursor_for_next_page"
}
```

Use `next_starting_after` value in the next request's `starting_after` parameter.

## Code Examples

### JavaScript

```javascript
const response = await fetch(
  'https://gateway.maton.ai/instantly/api/v2/campaigns?limit=10',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();
```

### Python

```python
import os
import requests

response = requests.get(
    'https://gateway.maton.ai/instantly/api/v2/campaigns',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    params={'limit': 10}
)
data = response.json()
```

## Notes

- Instantly API v2 uses snake_case for all field names
- Lead custom variables must be string, number, boolean, or null (no objects/arrays)
- The List Leads endpoint is POST (not GET) due to complex filtering requirements
- Campaign status values: 0=draft, 1=active, 2=paused, 3=completed
- Email verification may return `pending` status if it takes longer than 10 seconds
- Warmup operations return background job IDs - poll the background jobs endpoint for status
- IMPORTANT: When using curl commands, use `curl -g` when URLs contain brackets to disable glob parsing
- IMPORTANT: When piping curl output to `jq`, environment variables may not expand correctly. Use Python examples instead.

## Error Handling

| Status | Meaning |
|--------|---------|
| 400 | Missing Instantly connection or invalid request |
| 401 | Invalid or missing Maton API key |
| 403 | Insufficient API key scopes |
| 429 | Rate limited |
| 4xx/5xx | Passthrough error from Instantly API |

### Troubleshooting: API Key Issues

1. Check that the `MATON_API_KEY` environment variable is set:

```bash
echo $MATON_API_KEY
```

2. Verify the API key is valid by listing connections:

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Troubleshooting: Invalid App Name

1. Ensure your URL path starts with `instantly`. For example:

- Correct: `https://gateway.maton.ai/instantly/api/v2/campaigns`
- Incorrect: `https://gateway.maton.ai/api/v2/campaigns`
