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

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

The gateway 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:

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

Connection Management

Manage your Brevo OAuth connections at https://ctrl.maton.ai.

List Connections

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.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

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'brevo'}).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

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:

{
  "connection": {
    "connection_id": "b04dd695-d056-433b-baf9-0fb4eb3bde9e",
    "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

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 Brevo connections, specify which one to use with the Maton-Connection header:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/brevo/v3/account')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', 'b04dd695-d056-433b-baf9-0fb4eb3bde9e')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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

• Page 2: offset=50&limit=50
• Page 3: offset=100&limit=50

Code Examples

JavaScript

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

Python

import os
import requests

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

Python (Send Email)

import os
import requests

response = requests.post(
    'https://gateway.maton.ai/brevo/v3/smtp/email',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Content-Type': 'application/json'
    },
    json={
        'sender': {'name': 'John', 'email': '[e-mail]'},
        'to': [{'email': '[e-mail]', '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)

import os
import requests

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

# Create contact
response = requests.post(
    'https://gateway.maton.ai/brevo/v3/contacts',
    headers=headers,
    json={
        'email': '[e-mail]',
        '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:

echo $MATON_API_KEY

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

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
