Demo Apps

These client demo bundles are intended for local evaluation of hosted payin, S2S payin, lookup, and related integration behavior. They are standalone starter projects and are separate from the SDK library packages. During setup, each demo installs its matching SDK package from Payyd-hosted artifacts or feeds, so clients do not need to clone or copy the full SDK repositories.

Distribution recommendation: keep one manifest JSON file per release and have docs read links from that file. It prevents stale hardcoded links after upgrades.
