Buffer

Access the Buffer GraphQL API with managed authentication. Schedule and manage social media posts across Instagram, Facebook, Twitter, LinkedIn, TikTok, and more.

Quick Start

# Get account info with organizations
python <<'EOF'
import urllib.request, os, json
data = json.dumps({
    "query": "query { account { id email organizations { id name } } }"
}).encode()
req = urllib.request.Request('https://gateway.maton.ai/buffer/', 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/buffer/

Buffer uses a single GraphQL endpoint. All queries and mutations are sent as POST requests to this endpoint.

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 Buffer 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=buffer&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': 'buffer'}).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": "a71282a3-52be-473d-9273-22b4546dc146",
    "status": "ACTIVE",

    "url": "https://connect.maton.ai/?session_token=...",
    "app": "buffer",
    "metadata": {},
    "method": "API_KEY"
  }
}

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 Buffer connections, specify which one to use with the Maton-Connection header:

python <<'EOF'
import urllib.request, os, json
data = json.dumps({"query": "query { account { id } }"}).encode()
req = urllib.request.Request('https://gateway.maton.ai/buffer/', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
req.add_header('Maton-Connection', 'a71282a3-52be-473d-9273-22b4546dc146')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

If omitted, the gateway uses the default (oldest) active connection.

Pagination

Posts use cursor-based pagination:

python <<'EOF'
import urllib.request, os, json
data = json.dumps({
    "query": """
    query GetPosts($channelId: ChannelId!, $first: Int, $after: String) {
        posts(channelId: $channelId, first: $first, after: $after) {
            edges {
                node {
                    id
                    text
                }
                cursor
            }
            pageInfo {
                hasNextPage
                endCursor
            }
        }
    }
    """,
    "variables": {
        "channelId": "channel123",
        "first": 10,
        "after": "cursor_from_previous_page"
    }
}).encode()
req = urllib.request.Request('https://gateway.maton.ai/buffer/', 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

Code Examples

JavaScript

const response = await fetch('https://gateway.maton.ai/buffer/', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': `Bearer ${process.env.MATON_API_KEY}`
  },
  body: JSON.stringify({
    query: `query { account { id email organizations { id name } } }`
  })
});
const data = await response.json();
console.log(data.data.account);

Python

import os
import requests

response = requests.post(
    'https://gateway.maton.ai/buffer/',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    json={
        'query': 'query { account { id email organizations { id name } } }'
    }
)
data = response.json()
print(data['data']['account'])

Notes

Buffer uses GraphQL - all requests are POST to the base endpoint
Use introspection to discover the full schema
Posts require a connected channel with proper permissions
Scheduling requires timezone-aware datetime strings (ISO 8601)
Some features require paid Buffer plans
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

Status	Meaning
400	Missing Buffer connection or invalid GraphQL query
401	Invalid or missing Maton API key
429	Rate limited
4xx/5xx	Passthrough error from Buffer API

GraphQL Error Types:

InvalidInputError - Invalid mutation input
NotFoundError - Resource not found
UnauthorizedError - Insufficient permissions
LimitReachedError - Plan limits exceeded

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 buffer. For example:

Correct: https://gateway.maton.ai/buffer/
Incorrect: https://gateway.maton.ai/graphql
