hehe - I am only in draft mode. I was going to check with you. I think I will adjust to your schema, but I just had to have something to play with while waiting
- Fix response structs to match actual PingPay API (amount is object, recipient is object with address, not flat strings) - Fix double /api in URL construction for PingPay client - Fix callback URLs to route through backend before redirecting to frontend (PingPay → backend callback → frontend success/cancel) - Add BACKEND_URL env var for constructing PingPay callback URLs - Update implementation plan with verified API responses, remaining frontend/mock/invoice/test work documented in detail Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
