paynamics

Overview ¶

Package paynamics mocks Paynamics's (PH / SEA) payment API surface. Real-world shape: MD5-signed JSON envelopes with a response_code / response_advise / response_message triple. "GR001" is the canonical success code; "GR051" and the "GR0xx" family cover failures. The mock emits a fixed signature placeholder — callers verifying MD5 must detect the prefix and skip verification.

DTO shapes for Paynamics (PH / SEA) payment API surface. Derived from the production reference library (test-dto-/payments.go, structs: PaynamicsInitRespPayload, PaynamicsQueryRespPayload, PaynamicsRefundRespPayload, PaynamicsWebhookPayload, ...).

Paynamics uses an MD5-signed JSON envelope with a response_code / response_advise / response_message triple — "GR001" is the canonical success code; "GR051" and "GR0xx" cover the failure taxonomy. The real gateway historically emitted form-encoded responses; modern integrations use JSON. The mock emits JSON exclusively with a fixed signature placeholder.
