Mailgun

Access the Mailgun API with managed OAuth authentication. Send transactional emails, manage domains, routes, templates, mailing lists, suppressions, and webhooks.

Quick Start

# List domains python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://gateway.maton.ai/mailgun/v3/domains') 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/mailgun/v3/{resource} Replace {resource} with the actual Mailgun API endpoint path. The gateway proxies requests to api.mailgun.net/v3 (US region) and automatically injects your OAuth token. Regional Note: Mailgun has US and EU regions. The gateway defaults to US region (api.mailgun.net).

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

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

Connection Management

Manage your Mailgun 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=mailgun&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': 'mailgun'}).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": "78b5a036-c621-40c2-b74b-276195735af2", "status": "ACTIVE", "creation_time": "2026-02-12T02:24:16.551210Z", "last_updated_time": "2026-02-12T02:25:03.542838Z", "url": "https://connect.maton.ai/?session_token=...", "app": "mailgun", "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 Mailgun 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/mailgun/v3/domains') req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}') req.add_header('Maton-Connection', '78b5a036-c621-40c2-b74b-276195735af2') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF If omitted, the gateway uses the default (oldest) active connection.

JavaScript - Send Email

const formData = new URLSearchParams(); formData.append('from', 'sender@example.com'); formData.append('to', 'recipient@example.com'); formData.append('subject', 'Hello'); formData.append('text', 'Hello World!'); const response = await fetch( 'https://gateway.maton.ai/mailgun/v3/example.com/messages', { method: 'POST', headers: { 'Authorization': `Bearer ${process.env.MATON_API_KEY}`, 'Content-Type': 'application/x-www-form-urlencoded' }, body: formData.toString() } ); const result = await response.json(); console.log(result);

Python - Send Email

import os import requests response = requests.post( 'https://gateway.maton.ai/mailgun/v3/example.com/messages', headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}, data={ 'from': 'sender@example.com', 'to': 'recipient@example.com', 'subject': 'Hello', 'text': 'Hello World!' } ) print(response.json())

Python - List Domains

import os import requests response = requests.get( 'https://gateway.maton.ai/mailgun/v3/domains', headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'} ) domains = response.json() for domain in domains['items']: print(f"{domain['name']}: {domain['state']}")

Python - Create Route and Webhook

import os import requests headers = {'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'} domain = 'example.com' # Create route route_response = requests.post( 'https://gateway.maton.ai/mailgun/v3/routes', headers=headers, data={ 'priority': 0, 'description': 'Forward to webhook', 'expression': 'match_recipient("support@example.com")', 'action': 'forward("https://myapp.com/incoming-email")' } ) print(f"Route created: {route_response.json()}") # Create webhook webhook_response = requests.post( f'https://gateway.maton.ai/mailgun/v3/domains/{domain}/webhooks', headers=headers, data={ 'id': 'delivered', 'url': 'https://myapp.com/webhook/delivered' } ) print(f"Webhook created: {webhook_response.json()}")

Notes

Mailgun uses application/x-www-form-urlencoded for POST/PUT requests, not JSON Domain names must be included in most endpoint paths Routes are global (per account), not per domain Sandbox domains require authorized recipients for sending Dates are returned in RFC 2822 format Event logs are stored for at least 3 days Stats require at least one event parameter Templates use Handlebars syntax by default 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.

Rate Limits

OperationLimitSendingVaries by planAPI callsNo hard limit, but excessive requests may be throttled When rate limited, implement exponential backoff for retries.

Error Handling

StatusMeaning400Bad request or missing Mailgun connection401Invalid or missing Maton API key403Forbidden (e.g., sandbox domain restrictions)404Resource not found429Rate limited4xx/5xxPassthrough error from Mailgun API

Troubleshooting: API Key Issues

Check that the MATON_API_KEY environment variable is set: echo $MATON_API_KEY 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

Troubleshooting: Invalid App Name

Ensure your URL path starts with mailgun. For example: Correct: https://gateway.maton.ai/mailgun/v3/domains Incorrect: https://gateway.maton.ai/v3/domains

Troubleshooting: Sandbox Domain Restrictions

Sandbox domains can only send to authorized recipients. To send emails: Upgrade to a paid plan, or Add recipient addresses to authorized recipients in the Mailgun dashboard
