Digio — Protocol Analysis and OpenFinance Integration for Bank-Grade Digital Products

Technical Deliverables

• OpenAPI / Swagger specifications and API contracts (JSON Schema)
• Protocol analysis report (authorization flows, request signing, encryption, and session management)
• Runnable source code (Node.js / Python / Go optional), with Docker images and quick deployment scripts
• SDK samples and Postman collections
• Automated test scripts (integration tests + mock data) and acceptance test plan

Sample Interface: Transaction Reconciliation Query (Illustrative)

POST /api/v1/digio/statement
Content-Type: application/json
Authorization: Bearer <ACCESS_TOKEN>

{
  'account_id':'user_12345',
  'from':'2025-09-01',
  'to':'2025-09-30',
  'page':1,
  'page_size':100
}

Response 200 OK {
  'status':'OK',
  'total':254,
  'transactions':[{
     'id':'tx_20250910_001',
     'type':'DEBIT',
     'amount':-129.90,
     'merchant':'Supermercado',
     'category':'Groceries',
     'posted_at':'2025-09-10T12:23:00Z'
  }]
}

Compliance & Security

All work is based on client authorization or public/authorized APIs, adhering to local financial regulations (e.g., Central Bank rules) and privacy protection with minimal data retention. We can assist with compliance documentation and audit-log strategies.

Core Advantages

• Rapid deployment: protocol analysis → minimal viable API → acceptance loop
• Global experience: familiar with Brazil/Latin America payments and compliance nuances
• Verifiable source: runnable samples and integration tests for internal security audits
• Multi-platform support: Android / iOS reverse engineering, API standardization, and SDK distribution

Typical Delivery Timeline

Depends on complexity. Common project timeline examples:

• Basic reconciliation interfaces (authorization + transaction fetch): 5-10 business days
• Card management & payment chain: 8-20 business days
• Full middleware (payments + settlement + reports): 15-35 business days

Onboarding Steps

1. Provide the target app name (Digio is already provided) and your business scenario (reconciliation, acquiring, card management, etc.).
2. We perform protocol analysis: packet capture (with client authorization), authentication flow mapping, and request signing reverse engineering (referred to as protocol analysis / reverse engineering).
3. Design a stable external API (OpenAPI), and provide a simulated Mock environment for development and testing.
4. Deliver source code, SDK, Postman collections, automated test scripts and deployment guides.
5. Optional support: cloud deployment, operations handover, and compliance/audit support.

What We Need From You

• Specific goals (e.g., export monthly transactions CSV, real-time Pix callbacks, virtual card issuance)
• Whether there is an existing test environment, enterprise credentials, or authorized user samples
• Desired deliverable formats: OpenAPI, SDK (languages), report types
• Need for compliance / audit outputs (NDA, logging policy, minimal data retention)
