Money Manager – Expense Tracky API & Open Data Integration

1. Google Drive Backup Retrieval (Python pseudocode)

# Authenticate with Google Drive API using stored OAuth2 token
POST https://oauth2.googleapis.com/token
Body: { grant_type: "refresh_token", refresh_token: USER_REFRESH_TOKEN,
        client_id: CLIENT_ID, client_secret: CLIENT_SECRET }
Response: { access_token: "ya29.xxx", expires_in: 3600 }

# List Money Manager backup files in Drive
GET https://www.googleapis.com/drive/v3/files
Headers: { Authorization: "Bearer ya29.xxx" }
Params:  { q: "name contains 'MoneyManager' and mimeType='application/zip'",
           orderBy: "modifiedTime desc", pageSize: 1 }
Response: { files: [{ id: "1BxiM...", name: "MoneyManager_backup_20250318.zip",
                       modifiedTime: "2025-03-18T07:12:00Z" }] }

# Download and decrypt the backup archive
GET https://www.googleapis.com/drive/v3/files/1BxiM.../content?alt=media
→ decrypt_aes256(raw_bytes, user_passphrase)
→ unzip → money_manager.db  (SQLite3 database)
        

2. SQLite Transaction Extraction (Python pseudocode)

import sqlite3, json

conn = sqlite3.connect("money_manager.db")

# Query normalized transaction records
rows = conn.execute("""
  SELECT
    t.id,
    t.date,           -- Unix timestamp ms
    t.amount,         -- stored in minor currency units
    t.currency_code,
    t.type,           -- 'EXPENSE' | 'INCOME'
    c.name  AS category,
    sc.name AS subcategory,
    a.name  AS account,
    t.note,
    t.tags
  FROM transactions t
  LEFT JOIN categories  c  ON c.id  = t.category_id
  LEFT JOIN subcategories sc ON sc.id = t.subcategory_id
  LEFT JOIN accounts    a  ON a.id  = t.account_id
  WHERE t.date BETWEEN :from_ts AND :to_ts
  ORDER BY t.date DESC
""", { "from_ts": 1735689600000, "to_ts": 1738367999000 }).fetchall()

output = [dict(zip([d[0] for d in conn.description], r)) for r in rows]
print(json.dumps(output, indent=2))
# → [{"id":1042,"date":1736000000000,"amount":2450,
#      "currency_code":"USD","type":"EXPENSE",
#      "category":"Food & Dining","subcategory":"Groceries",
#      "account":"Chase Checking","note":"Whole Foods","tags":"weekly"}, ...]
        

3. Automated CSV Export & Webhook Delivery (Node.js pseudocode)

// Trigger Money Manager CSV export via Android ADB intent
const { execSync } = require('child_process');
execSync(`adb shell am broadcast \
  -a com.officialbrain.money_manager.EXPORT \
  --es format CSV \
  --es date_from "2025-01-01" \
  --es date_to   "2025-03-31" \
  --es output    "/sdcard/Download/mm_export.csv"`);

// Pull the file from device
execSync('adb pull /sdcard/Download/mm_export.csv ./exports/');

// Parse CSV and POST to downstream webhook
const csv  = require('fs').readFileSync('./exports/mm_export.csv', 'utf8');
const rows = parseCSV(csv);   // normalize headers, types, currency

await fetch('https://your-api.example.com/ingest/transactions', {
  method:  'POST',
  headers: { 'Content-Type': 'application/json',
             'Authorization': `Bearer ${process.env.API_TOKEN}` },
  body:    JSON.stringify({ source: 'money_manager', records: rows })
});
// Response: { accepted: 143, skipped_duplicates: 2, errors: 0 }
        

Deliverables checklist

• SQLite schema documentation (tables, relationships, field types)
• Backup file decryption and parsing module (Python or Node.js)
• Google Drive API client for automated backup retrieval
• CSV / JSON export normalization library with unit tests
• OpenAPI specification for the extraction REST endpoint
• Category taxonomy mapping table (Money Manager → client schema)
• GDPR / CCPA compliance guidance and data-retention policy template
• Integration test suite against sample backup files
• Full technical documentation and a sample integration guide

Engagement models

Source code delivery from $300 — We hand over all runnable source code, schema documentation, and integration guides. You review the complete deliverable first; payment is made after satisfaction. No upfront deposit required for standard integrations.

Pay-per-call API billing — Access our hosted extraction endpoint and pay only for the API calls you make. No upfront fee, no infrastructure to manage. Ideal for teams that want to validate the integration before building their own pipeline. Pricing scales with call volume; contact us for a rate sheet.
