tillpay

Overview ¶

Package tillpay mocks the TillPayment acquirer API.

Real-world shape (from TillPayment's merchant integration docs and the production reference DTO): HMAC-SHA512 signed requests, responses carry `{ success, uuid, purchaseId, returnType, paymentMethod }`, and webhooks use a separate envelope centred on `{ result, transactionStatus, uuid }`. The `amount` field on the webhook is a *string*, not a number — a TillPayment quirk we preserve so integration consumers see realistic data.

DTO shapes for TillPayment's transaction response and webhook notifications. Derived from the production reference library (test-dto-/tillpayment.go). Scoped to the fields this mock emits; extend when a failure mode needs more surface area. TillPayment is a card-acquiring platform; its wire format centres around a `uuid` (gateway txn id), a `purchaseId`, and a success/result/transactionStatus triple.
