espay

Overview ¶

Package espay mocks ESPay (Indonesia) payment API. Real-world shape: RSA-2048 signed payloads with a uniform error_code / error_message envelope. "0000" is the success code; anything else is an ESPxx-style failure. We mock with a fixed signature placeholder.

DTO shapes for ESPay's (Indonesia) payment API surface. Derived from the production reference library (test-dto-/payments.go, structs: ESPayInquireResponse, ESPayPaymentStatusResponse, ESPayWebhookResponse, ESPayRefundResponse, ...).

ESPay uses RSA-signed JSON payloads with a strict error_code / error_message envelope — "0000" for success, arbitrary ESPxx codes otherwise. We mock the signature field with a fixed placeholder; callers that verify signatures should short-circuit on the mock prefix.
