# Brevo

Access the Brevo API with managed OAuth authentication. Send transactional emails, manage contacts and lists, create email campaigns, and work with templates.

## Quick Start

```bash
# Get account info
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/brevo/v3/account')
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://api.maton.ai/brevo/v3/{resource}
```

Maton proxies requests to `api.brevo.com` and automatically injects your OAuth token.

## 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 Brevo OAuth connections at `https://api.maton.ai`.

### List Connections

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections?app=brevo&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': 'brevo'}).encode()
req = urllib.request.Request('https://api.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://api.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": "{connection_id}",
    "status": "ACTIVE",
    "creation_time": "2026-02-09T19:51:00.932629Z",
    "last_updated_time": "2026-02-09T19:51:30.123456Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "brevo",
    "metadata": {}
  }
}
```

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

### Delete Connection

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.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 Brevo connections, specify which one to use with the `Maton-Connection` header:

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/brevo/v3/account')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '{connection_id}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

If you have multiple connections, always include this header to ensure requests go to the intended account.

## Security & Permissions

- Access is scoped to contacts, email campaigns, transactional emails, lists, and senders within the connected Brevo account.
- **All write operations require explicit user approval.** Before executing any create, update, or delete call, confirm the target resource and intended effect with the user.

## Pagination

Brevo uses offset-based pagination:

```bash
GET /brevo/v3/contacts?limit=50&offset=0
```

**Parameters:**
- `limit` - Number of results per page (varies by endpoint, typically max 500)
- `offset` - Starting index (0-based)

**Response includes count:**
```json
{
  "contacts": [...],
  "count": 150
}
```

To get the next page, increment offset by limit:
- Page 1: `offset=0&limit=50`
- Page 2: `offset=50&limit=50`
- Page 3: `offset=100&limit=50`

## Code Examples

### JavaScript

```javascript
const response = await fetch(
  'https://api.maton.ai/brevo/v3/contacts',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();
console.log(data.contacts);
```

### Python

```python
import os
import requests

response = requests.get(
    'https://api.maton.ai/brevo/v3/contacts',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)
data = response.json()
print(data['contacts'])
```

### Python (Send Email)

```python
import os
import requests

response = requests.post(
    'https://api.maton.ai/brevo/v3/smtp/email',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Content-Type': 'application/json'
    },
    json={
        'sender': {'name': 'John', 'email': 'john@example.com'},
        'to': [{'email': 'recipient@example.com', 'name': 'Jane'}],
        'subject': 'Hello!',
        'htmlContent': '<html><body><h1>Hi Jane!</h1></body></html>'
    }
)
result = response.json()
print(f"Sent! Message ID: {result['messageId']}")
```

### Python (Create Contact and Add to List)

```python
import os
import requests

headers = {
    'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
    'Content-Type': 'application/json'
}

# Create contact
response = requests.post(
    'https://api.maton.ai/brevo/v3/contacts',
    headers=headers,
    json={
        'email': 'newuser@example.com',
        'attributes': {'FIRSTNAME': 'New', 'LASTNAME': 'User'},
        'listIds': [2]
    }
)
contact = response.json()
print(f"Created contact ID: {contact['id']}")
```

## Notes

- All endpoints require the `/v3/` prefix in the path
- Attribute names must be in UPPERCASE
- Contact identifiers can be email, phone, or ID
- Sender email addresses must be verified in Brevo
- Template parameters use `{{params.name}}` syntax
- PUT and DELETE operations return 204 No Content on success
- Rate limits: 300 calls/minute on free plans, higher on paid plans
- IMPORTANT: When piping curl output to `jq` or other commands, environment variables like `$MATON_API_KEY` may not expand correctly in some shell environments

## Error Handling

| Status | Meaning |
|--------|---------|
| 400 | Missing Brevo connection or bad request |
| 401 | Invalid or missing Maton API key |
| 404 | Resource not found |
| 429 | Rate limited |
| 4xx/5xx | Passthrough error from Brevo API |

Rate limit headers in response:
- `x-sib-ratelimit-limit` - Request limit
- `x-sib-ratelimit-remaining` - Remaining requests
- `x-sib-ratelimit-reset` - Reset time

### Troubleshooting: Invalid API Key

**When you receive an "Invalid API key" error, ALWAYS follow these steps before concluding there is an issue:**

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://api.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
```
