My Finances — Integration & OpenFinance Services

Standard deliverables

• API specification (OpenAPI 3.0) for Accounts, Transactions, Attachments and Import endpoints
• Protocol analysis report and data mapping (field-level)
• Production-ready connector code (Node.js / Python) with Docker deployment
• OFX/CSV parser & normalization module + sample import scripts
• Automated test suite, integration tests and sample client SDK

Example API: Fetch transactions (pseudocode)

# POST /api/v1/finance/transactions
# Auth: Bearer <SERVICE_TOKEN>
{
  'account_id': 'checking-123',
  'from_date': '2025-09-01',
  'to_date': '2025-09-30',
  'page': 1,
  'per_page': 100
}

Response: {
  'status': 'OK',
  'page': 1,
  'per_page': 100,
  'total': 286,
  'transactions': [
    { 'id':'tx-0001','date':'2025-09-02','amount':-45.20,'currency':'BRL','category':'Groceries','notes':'Supermarket','attachments':[ 'url1' ] },
    { 'id':'tx-0002','date':'2025-09-05','amount':1200.00,'currency':'BRL','category':'Salary','notes':'Company payroll' }
  ]
}

Typical integration scenarios

Account aggregation for personal finance dashboards, automated bookkeeping (attach receipts and export Excel/PDF), tax reporting exports, backup & migration between finance apps, and bank statement imports (OFX).

Core benefits

• Turnkey API with OpenAPI docs and sample SDKs
• Reduced time-to-market for bookkeeping, accounting, and aggregation features
• Privacy-first, consent-driven data extraction workflows
• Cross-platform code: runs on Android/iOS backend proxies or cloud functions

Integration checklist

1. Provide target use-cases (transactions, OFX import, attachments export)
2. Provide sample data or sandbox credentials if available
3. Confirm legal & compliance constraints (consent flow, retention limits)
4. Choose deployment target (customer cloud, our managed endpoint, or on-prem)

API Integration Instructions (quick start)
