Payment Provider Framework

If you're building a payment connector as a VTEX IO app, this walks you through wiring PaymentProviderService, setting up configuration.json with payment methods and feature flags, and handling the TypeScript 3.9.7 constraints that builder-hub enforces. It covers SecureExternalClient for card flows with Secure Proxy, the retry semantics for Gateway callbacks, and safe dependency resolutions so your build doesn't explode with hundreds of type errors from modern syntax in transitive packages. The skill explicitly splits out protocol contracts, idempotency, async flows, and PCI rules into separate skills, keeping this focused on the IO runtime plumbing. Useful when you need the cookbook for vtex link, affiliation testing, and homologation artifacts rather than hunting through fragmented docs.
