Transact PSP Adapter API

Provider-agnostic gateway for submitting payment requests against a completed card capture session. Maps a generic PSP request to the selected provider (e.g. Worldpay, Opayo, Vestafone), injects the captured card tokens, forwards the call to the provider service, and normalises the response. Supports authorise, authorise-and-settle, tokenise, zero-pence authorisation, and token-based variants.
