Paystone DataCandy API
The public, documented REST API for Paystone's DataCandy gift-card and loyalty platform, built on API Platform (Hydra/JSON-LD) and served from api.paystone.com. It exposes 28 documented paths across 14 resource groups — client and merchant management, contacts, gift/loyalty/prepaid/promo account types, loyalty and prepaid transactions, rewards and items, member and balance portals, user management, and webhook management. All endpoints require a JWT bearer token. An interactive Swagger UI is published at api.paystone.com/docs and a machine-readable OpenAPI 3.1 export is downloadable from the same host.
