ConnectPSP API (2.0.0)

ConnectPSP is a PIX payment gateway designed for high-throughput platforms such as digital wallets, betting companies, and fintechs.

This API allows you to:

  • 💸 Receive payments via PIX (Cash-In) — standard QR Code or OpenFinance
  • 🏦 Send payments via PIX key or bank account data (Cash-Out)
  • 📊 Manage your wallet — check consolidated balances and rebalance between transactional and proprietary accounts
  • 🪝 Receive real-time events via Webhooks as transactions progress

Authentication

All endpoints (except POST /auth/token) require two headers:

HeaderDescription
AuthorizationBearer <jwt_token> — obtained from POST /auth/token
ApplicationTokenFixed GUID token that identifies your integration

For financial operations (Cash-Out, Rebalance), an additional header is required:

HeaderDescription
DigitalSignatureHMAC-SHA256 hash of your JWT + CryptoToken. See Authentication Guide

Idempotency

For POST /cash-in and POST /cash-out, we strongly recommend sending the X-Idempotency-Key header (UUID v4). This guarantees that network retries do not result in duplicate transactions.
