Zoho Mail

Access the Zoho Mail API with managed OAuth authentication. Send, receive, search, and manage emails with full folder and label management.

Quick Start

# List all accounts python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://gateway.maton.ai/zoho-mail/api/accounts') 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/zoho-mail/{native-api-path} Replace {native-api-path} with the actual Zoho Mail API endpoint path. The gateway proxies requests to mail.zoho.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

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

Connection Management

Manage your Zoho Mail 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=zoho-mail&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': 'zoho-mail'}).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": "21fd90f9-5935-43cd-b6c8-bde9d915ca80", "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": "zoho-mail", "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 Zoho Mail 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/zoho-mail/api/accounts') req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}') req.add_header('Maton-Connection', '21fd90f9-5935-43cd-b6c8-bde9d915ca80') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF If omitted, the gateway uses the default (oldest) active connection.

Account Operations

Pagination

Zoho Mail uses offset-based pagination: GET /zoho-mail/api/accounts/{accountId}/messages/view?folderId={folderId}&start=0&limit=50 start: Offset index (default: 0) limit: Number of records to return (default: 50) For subsequent pages, increment start by limit: Page 1: start=0&limit=50 Page 2: start=50&limit=50 Page 3: start=100&limit=50

JavaScript

const response = await fetch( 'https://gateway.maton.ai/zoho-mail/api/accounts', { headers: { 'Authorization': `Bearer ${process.env.MATON_API_KEY}` } } ); const data = await response.json();

Python

import os import requests response = requests.get( 'https://gateway.maton.ai/zoho-mail/api/accounts', headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'} ) data = response.json()

Notes

Account IDs are required for most operations - first call /api/accounts to get your account ID Message IDs and Folder IDs are numeric strings The fromAddress must be associated with the authenticated account Default folders include: Inbox, Drafts, Templates, Snoozed, Sent, Spam, Trash, Outbox Supported encodings: Big5, EUC-JP, EUC-KR, GB2312, ISO-2022-JP, ISO-8859-1, KOI8-R, Shift_JIS, US-ASCII, UTF-8, WINDOWS-1251 Some operations (labels, folder management, sending) require additional OAuth scopes. If you receive an INVALID_OAUTHSCOPE error, contact Maton support at support@maton.ai with the specific operations/APIs you need and your use-case IMPORTANT: When using curl commands, use curl -g when URLs contain brackets 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

Error Handling

StatusMeaning400Missing Zoho Mail connection or invalid request401Invalid or missing Maton API key429Rate limited4xx/5xxPassthrough error from Zoho Mail 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 zoho-mail. For example: Correct: https://gateway.maton.ai/zoho-mail/api/accounts Incorrect: https://gateway.maton.ai/api/accounts
