Slack

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

Quick Start

CLI:

maton slack message send --channel C0123456789 --text 'Hello from Maton!'

maton api '/slack/api/chat.postMessage'

Python:

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'channel': 'C0123456789', 'text': 'Hello from Maton!'}).encode()
req = urllib.request.Request('https://api.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://api.maton.ai/slack/{method}

Maton proxies requests to slack.com and automatically injects your OAuth token.

Installation

NPM:

npm install -g @maton/cli

Homebrew:

brew install maton-ai/cli/maton

Authentication

CLI:

maton login                          # Opens browser for API key
maton login --interactive            # Skip browser, paste API key directly
maton whoami                         # Show current auth state

Manual:

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

export MATON_API_KEY="YOUR_API_KEY"

Connection Management

Manage your Slack OAuth connections at https://api.maton.ai.

List Connections

CLI:

maton connection list slack --status ACTIVE

maton api -X GET /connections -f app=slack -f status=ACTIVE

Python:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.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

CLI:

maton connection create slack

maton api /connections -f app=slack

Python:

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'slack'}).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

CLI:

maton connection view {connection_id}

maton api /connections/{connection_id}

Python:

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": "slack",
    "metadata": {}
  }
}

Open the returned url in a browser to complete OAuth authorization.

Delete Connection

CLI:

maton connection delete {connection_id}

maton api -X DELETE /connections/{connection_id}

Python:

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 Slack connections, specify which one to use:

CLI:

maton slack message send --channel C0123456789 --text 'Hello!' --connection {connection_id}

maton api /slack/api/chat.postMessage --connection {connection_id}

Python:

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'channel': 'C0123456789', 'text': 'Hello!'}).encode()
req = urllib.request.Request('https://api.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', '{connection_id}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

If you have multiple connections, always specify the connection to ensure requests go to the intended account.

Security & Permissions

Access is scoped to messages, channels, users, files, and reactions within the connected Slack 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.

Code Examples

CLI

# Send a message to a channel
maton slack message send --channel C0123456789 --text 'Hello team'

# List channels
maton slack channel list --types public_channel,private_channel

# Look up a user by email
maton slack user lookup --email alice@example.com

# Add a reaction to a message
maton slack reaction add --channel C012 --ts 1700000000.000100 --emoji thumbsup

JavaScript

const response = await fetch('https://api.maton.ai/slack/api/chat.postMessage', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': `Bearer ${process.env.MATON_API_KEY}`
  },
  body: JSON.stringify({ channel: 'C0123456', text: 'Hello!' })
});
const result = await response.json();
console.log(result);

Python

import os
import requests

response = requests.post(
    'https://api.maton.ai/slack/api/chat.postMessage',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    json={'channel': 'C0123456', 'text': 'Hello!'}
)
print(response.json())

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

Status	Meaning
400	Missing Slack connection
401	Invalid or missing Maton API key
429	Rate limited (10 req/sec per account)
4xx/5xx	Passthrough 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

CLI:

Check your auth state:

maton whoami

Verify the API key is valid by listing connections:

maton connection list

Manual:

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://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

Ensure your URL path starts with slack. For example:

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