Google Classroom

Access the Google Classroom API with managed OAuth authentication. Manage courses, coursework, students, teachers, announcements, and submissions.

Quick Start

# List all courses
python3 <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/google-classroom/v1/courses')
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-classroom/{api-path}

The Google Classroom API uses the path pattern:

https://gateway.maton.ai/google-classroom/v1/{resource}

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

  1. Sign in or create an account at maton.ai
  2. Go to maton.ai/settings
  3. Copy your API key

Connection Management

Manage your Google Classroom OAuth connections at https://ctrl.maton.ai.

List Connections

python3 <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=google-classroom&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

python3 <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'google-classroom'}).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

python3 <<'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": "8efa1361-0e86-40b1-a63b-53a5051f8ac6",
    "status": "ACTIVE",
    "creation_time": "2026-02-14T00:00:00.000000Z",
    "last_updated_time": "2026-02-14T00:00:00.000000Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "google-classroom",
    "metadata": {}
  }
}

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

Delete Connection

python3 <<'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 Google Classroom connections, specify which one to use with the Maton-Connection header:

python3 <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/google-classroom/v1/courses')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '8efa1361-0e86-40b1-a63b-53a5051f8ac6')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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

Code Examples

JavaScript

// List all courses
const response = await fetch(
  'https://gateway.maton.ai/google-classroom/v1/courses',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();
console.log(data.courses);

Python

import os
import requests

# List all courses
response = requests.get(
    'https://gateway.maton.ai/google-classroom/v1/courses',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)
data = response.json()
print(data['courses'])

Create Assignment Example

import os
import requests

course_id = "825635865485"

# Create an assignment
assignment = {
    "title": "Week 1 Homework",
    "description": "Complete exercises 1-10",
    "workType": "ASSIGNMENT",
    "state": "PUBLISHED",
    "maxPoints": 100,
    "dueDate": {"year": 2026, "month": 3, "day": 15},

        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Content-Type': 'application/json'
    },
    json=assignment

print(response.json())

Notes

  • updateMask Required: PATCH requests require the updateMask query parameter specifying which fields to update
  • Course Deletion: Courses must be archived (courseState: "ARCHIVED") before they can be deleted
  • Student Submissions: Course work must be in PUBLISHED state to access student submissions
  • User IDs: Use me to refer to the current authenticated user
  • Timestamps: Dates use {year, month, day} format; times use {hours, minutes} format
  • IMPORTANT: When piping curl output to jq or other commands, environment variables like $MATON_API_KEY may not expand correctly in some shell environments
