mailchimp（Mailchimp 邮件管理）

Mailchimp

Access the Mailchimp Marketing API with managed OAuth authentication. Manage audiences, campaigns, templates, automations, reports, and subscribers for email marketing.

Quick Start

# List all audiences
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/mailchimp/3.0/lists')
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/mailchimp/{native-api-path}

Maton proxies requests to your Mailchimp data center 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 Mailchimp OAuth connections at https://api.maton.ai.

List Connections

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections?app=mailchimp&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': 'mailchimp'}).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

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:

{
  "connection": {
    "connection_id": "{connection_id}",
    "status": "ACTIVE",
    "creation_time": "2025-12-08T07:20:53.488460Z",
    "last_updated_time": "2026-01-31T20:03:32.593153Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "mailchimp",
    "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://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 Mailchimp connections, specify which one to use with the Maton-Connection header:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/mailchimp/3.0/lists')
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 audiences, campaigns, templates, automations, reports, and manage subscribers within the connected Mailchimp 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.

EOF

Response includes total_items for calculating total pages:

{
  "lists": [...],
  "total_items": 250
}

Code Examples

JavaScript

const response = await fetch(
  'https://api.maton.ai/mailchimp/3.0/lists',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();

Python

import os
import requests
import hashlib

# Get lists
response = requests.get(
    'https://api.maton.ai/mailchimp/3.0/lists',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)
data = response.json()

# Add a subscriber
list_id = 'abc123def4'
email = 'newuser@example.com'

response = requests.post(
    f'https://api.maton.ai/mailchimp/3.0/lists/{list_id}/members',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Content-Type': 'application/json'
    },
    json={
        'email_address': email,
        'status': 'subscribed'
    }
)

# Get subscriber hash for updates
subscriber_hash = hashlib.md5(email.lower().encode()).hexdigest()

Notes

• List IDs are 10-character alphanumeric strings
• Subscriber hashes are MD5 hashes of lowercase email addresses
• Timestamps are in ISO 8601 format
• The API has a 120-second timeout on calls
• Maximum 1000 records per request for list endpoints
• "Audience" and "list" are used interchangeably (app vs API terminology)
• "Contact" and "member" are used interchangeably (app vs API terminology)
• IMPORTANT: When using curl commands, use curl -g when URLs contain brackets (fields[], sort[], records[]) to disable glob parsing
• IMPORTANT: When piping curl output to jq or other commands, environment variables like $MATON_API_KEY may not expand correctly in some shell environments. You may get "Invalid API key" errors when piping.

Response Codes

Mailchimp error responses include detailed information:

{
  "type": "https://mailchimp.com/developer/marketing/docs/errors/",
  "title": "Invalid Resource",
  "status": 400,
  "detail": "The resource submitted could not be validated.",
  "instance": "abc123-def456",
  "errors": [
    {
      "field": "email_address",
      "message": "This value should be a valid email."
    }
  ]
}

Troubleshooting: API Key Issues

1. Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

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

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

Troubleshooting: Invalid App Name

1. Ensure your URL path starts with mailchimp. For example:

• Correct: https://api.maton.ai/mailchimp/3.0/lists
• Incorrect: https://api.maton.ai/3.0/lists
