PPP Endpoint Implementation

When this skill applies

Use this skill when:

• Building a new payment connector middleware that integrates a PSP with the VTEX Payment Gateway
• Implementing, debugging, or extending any of the 9 PPP endpoints
• Preparing a connector for VTEX Payment Provider Test Suite homologation

Do not use this skill for:

• Idempotency and duplicate prevention logic — use payment-idempotency
• Async payment flows and callback URLs — use payment-async-flow
• PCI compliance and Secure Proxy card handling — use payment-pci-security
• POS / VTEX Sales App card-present payments (Venda Direta Credito, Venda Direta Debito, terminal Payment Apps) — use payment-ppp-pos together with this skill for endpoint shapes
