# Gmail Access the Gmail API with managed OAuth authentication. Read, send, and manage emails, threads, labels, and drafts. ## Quick Start ```bash # List messages python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://gateway.maton.ai/google-mail/gmail/v1/users/me/messages?maxResults=10') 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/google-mail/{native-api-path} ``` Replace `{native-api-path}` with the actual Gmail API endpoint path. The gateway proxies requests to `gmail.googleapis.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 Google OAuth connections at `https://ctrl.maton.ai`. ### List Connections ```bash python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://ctrl.maton.ai/connections?app=google-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 ```bash python <<'EOF' import urllib.request, os, json data = json.dumps({'app': 'google-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 ```bash 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:** ```json { "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": "google-mail", "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://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 Gmail connections, specify which one to use with the `Maton-Connection` header: ```bash python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://gateway.maton.ai/google-mail/gmail/v1/users/me/messages') 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. ## API Reference ### List Messages ```bash GET /google-mail/gmail/v1/users/me/messages?maxResults=10 ``` With query filter: ```bash GET /google-mail/gmail/v1/users/me/messages?q=is:unread&maxResults=10 ``` ### Get Message ```bash GET /google-mail/gmail/v1/users/me/messages/{messageId} ``` With metadata only: ```bash GET /google-mail/gmail/v1/users/me/messages/{messageId}?format=metadata&metadataHeaders=From&metadataHeaders=Subject&metadataHeaders=Date ``` ### Send Message ```bash POST /google-mail/gmail/v1/users/me/messages/send Content-Type: application/json { "raw": "BASE64_ENCODED_EMAIL" } ``` ### List Labels ```bash GET /google-mail/gmail/v1/users/me/labels ``` ### List Threads ```bash GET /google-mail/gmail/v1/users/me/threads?maxResults=10 ``` ### Get Thread ```bash GET /google-mail/gmail/v1/users/me/threads/{threadId} ``` ### Modify Message Labels ```bash POST /google-mail/gmail/v1/users/me/messages/{messageId}/modify Content-Type: application/json { "addLabelIds": ["STARRED"], "removeLabelIds": ["UNREAD"] } ``` ### Trash Message ```bash POST /google-mail/gmail/v1/users/me/messages/{messageId}/trash ``` ### Create Draft ```bash POST /google-mail/gmail/v1/users/me/drafts Content-Type: application/json { "message": { "raw": "BASE64URL_ENCODED_EMAIL" } } ``` ### Send Draft ```bash POST /google-mail/gmail/v1/users/me/drafts/send Content-Type: application/json { "id": "{draftId}" } ``` ### Get Profile ```bash GET /google-mail/gmail/v1/users/me/profile ``` ## Query Operators Use in the `q` parameter: - `is:unread` - Unread messages - `is:starred` - Starred messages - `from:email@example.com` - From specific sender - `to:email@example.com` - To specific recipient - `subject:keyword` - Subject contains keyword - `after:2024/01/01` - After date - `before:2024/12/31` - Before date - `has:attachment` - Has attachments ## Code Examples ### JavaScript ```javascript const response = await fetch( 'https://gateway.maton.ai/google-mail/gmail/v1/users/me/messages?maxResults=10', { headers: { 'Authorization': `Bearer ${process.env.MATON_API_KEY}` } } ); ``` ### Python ```python import os import requests response = requests.get( "https://gateway.maton.ai/google-mail/gmail/v1/users/me/messages", headers={"Authorization": f"Bearer {os.environ['MATON_API_KEY']}"}, params={"maxResults": 10, "q": "is:unread"}, ) ``` ## Notes - Use `me` as userId for the authenticated user - Message body is base64url encoded in the `raw` field - Common labels: `INBOX`, `SENT`, `DRAFT`, `STARRED`, `UNREAD`, `TRASH` - IMPORTANT: When using curl commands, use `curl -g` when URLs contain brackets (`fields[]`, `sort[]`, `records[]`) to disable glob parsing - IMPORTANT: When piping curl output to `jq` or other commands, environment variables like `$MATON_API_KEY` may not expand correctly in some shell environments. You may get "Invalid API key" errors when piping. ## Error Handling | Status | Meaning | |--------|---------| | 400 | Missing Gmail connection | | 401 | Invalid or missing Maton API key | | 429 | Rate limited (10 req/sec per account) | | 4xx/5xx | Passthrough error from Gmail API | ### Troubleshooting: API Key Issues 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://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 1. Ensure your URL path starts with `google-mail`. For example: - Correct: `https://gateway.maton.ai/google-mail/gmail/v1/users/me/messages` - Incorrect: `https://gateway.maton.ai/gmail/v1/users/me/messages` ## Resources - [Gmail API Overview](https://developers.google.com/gmail/api/reference/rest) - [List Messages](https://developers.google.com/gmail/api/reference/rest/v1/users.messages/list) - [Get Message](https://developers.google.com/gmail/api/reference/rest/v1/users.messages/get) - [Send Message](https://developers.google.com/gmail/api/reference/rest/v1/users.messages/send) - [List Threads](https://developers.google.com/gmail/api/reference/rest/v1/users.threads/list) - [List Labels](https://developers.google.com/gmail/api/reference/rest/v1/users.labels/list) - [Create Draft](https://developers.google.com/gmail/api/reference/rest/v1/users.drafts/create) - [Maton Community](https://discord.com/invite/dBfFAcefs2) - [Maton Support](mailto:support@maton.ai)
