API Integration Guide (Getting Started)

  1. Provide the target App name and integration scope (e.g., transactions sync, Pix payments, card management, statement export)
  2. We perform protocol analysis and deliver a technical plan (2-5 business days).
  3. Upon agreement, we develop and deliver runnable APIs and a test environment (3-10 business days).
  4. After validation, we provide deployment scripts, OpenAPI docs, and acceptance report.
  5. Recommend security hardening and compliance audits before go-live (NDA and third-party audit available).

Quick Example: Device binding & session refresh (pseudo-code)

// 1) Bind device using app-token (simulated authorization flow)
POST /api/v1/itau/device-bind
{ "device_id": "device-uuid", "auth_code": "sms-or-app-code" }

// 2) Refresh session
POST /oauth/token
{ "grant_type":"refresh_token", "refresh_token":"<REFRESH>" }

// 3) Register webhook for real-time transaction pushes
POST /api/v1/webhooks
{ "url":"https://your.service/webhook/itau", "events":["transaction.posted","pix.status"] }
