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

headers : {
'Content-Type' : 'application/json' ,
'Authorization' : `Bearer ${process.env.MATON_API_KEY} `

});
Python import os
import requests

headers={'Authorization' : f'Bearer {os.environ["MATON_API_KEY" ]} ' },
json={'channel' : 'C0123456' , 'text' : 'Hello!' }
)
Notes
Channel IDs start with C (public), G (private/group), or D (DM)
User IDs start with U, Team IDs start with T
Message timestamps (ts) are used as unique identifiers
Use mrkdwn type for Slack-flavored markdown formatting
Thread replies use thread_ts to reference the parent message
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
Troubleshooting: API Key Issues
Check that the MATON_API_KEY environment variable is set:
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
