Slack

Access the Slack API with managed OAuth authentication. Send messages, manage channels, list users, and automate Slack workflows.

Quick Start

# Post a message to a channel python <<'EOF' import urllib.request, os, json data = json.dumps({'channel': 'C0123456789', 'text': 'Hello from Maton!'}).encode() req = urllib.request.Request('https://gateway.maton.ai/slack/api/chat.postMessage', 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

Base URL

https://gateway.maton.ai/slack/{method} The gateway proxies requests to slack.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 Slack 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=slack&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': 'slack'}).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": "slack", "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 Slack connections, specify which one to use with the Maton-Connection header: python <<'EOF' import urllib.request, os, json data = json.dumps({'channel': 'C0123456789', 'text': 'Hello!'}).encode() req = urllib.request.Request('https://gateway.maton.ai/slack/api/chat.postMessage', data=data, method='POST') req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}') req.add_header('Maton-Connection', '21fd90f9-5935-43cd-b6c8-bde9d915ca80') req.add_header('Content-Type', 'application/json') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF If omitted, the gateway uses the default (oldest) active connection.

Authentication

Auth Test GET /slack/api/auth.test Returns current user and team info.

Notes

Channel IDs: C (public), G (private/group), D (DM) User IDs start with U, Bot IDs start with B, Team IDs start with T Message timestamps (ts) are unique identifiers Use mrkdwn type for Slack-flavored markdown formatting Thread replies use thread_ts to reference the parent message Cursor-based pagination: use cursor from response_metadata.next_cursor

Shell Notes

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

StatusMeaning400Missing Slack connection401Invalid or missing Maton API key429Rate limited (10 req/sec per account)4xx/5xxPassthrough error from Slack API Missing Scope Errors: If you encounter missing_scope errors, contact Maton Support to request additional scopes for your connection.

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 slack. For example: Correct: https://gateway.maton.ai/slack/api/chat.postMessage Incorrect: https://gateway.maton.ai/api/chat.postMessage
