BNA+ (Banco Nación) API Integration & Open Banking/Open Finance

Standard Deliverables

• API specifications (OpenAPI / Swagger) with sample requests
• Protocol analysis report (OAuth2 / OpenID Connect / SCA / 3DS)
• runnable backend samples (Node.js / Python) with Docker deployment instructions
• API tests, integration tests and deployment plan
• Compliance guidance (data minimization, logs retention, KYC guidelines)

Interface Example: Query Account Transactions (pseudo-code)

# Query account balance (example)
GET /api/v1/bna/accounts/{account_id}/balance
Authorization: Bearer <ACCESS_TOKEN>

Response 200 OK
{
  "account_id": "AR12345678",
  "currency": "ARS",
  "available_balance": 12500.50,
  "ledger_balance": 12750.50,
  "as_of": "2025-10-28T14:22:00Z"
}

# Request transactions
POST /api/v1/bna/accounts/transactions
{
  "account_id": "AR12345678",
  "from_date": "2025-09-01",
  "to_date": "2025-09-30",
  "page": 1,
  "page_size": 100
}

Key Integration Scenarios

Account binding and session management, transaction reconciliation exports, QR payments and refunds, cardless withdrawals authorization, and end-to-end processes for deposits/loans synchronization.

Integration Guide (Quick Start)

1. Provide target App name (BNA+), package name (com.banconacion.bnamas) and concrete needs (e.g., transactions export / QR acceptance / cardless withdrawals).
2. Confirm available authorization method: public API, test credentials or need to implement an authorization bridge via protocol analysis.
3. We will deliver: API documentation (OpenAPI), sample backend code, integration tests and run instructions.
4. Typical initial delivery cycle: 5–12 business days (depending on authorization and complexity).

Minimum deliverables: target feature list, whether there is a test account/sandbox, compliance/privacy requirements (e.g., KYC processing) and preferred delivery format (Swagger/SDK).

Compliance & Security

All work is based on client authorization or public/authorized APIs; we provide data minimization guidance, logging retention and regulatory compliance recommendations, and can assist with NDA and data processing agreements.
