End-to-end onboarding: integration into Boot/Cloud projects, merchant cert import, callback signature debugging, and extending new endpoints in 3 minutes.
Overview
The Payment Gateway plugin unifies integration with major payment providers (WeChat, Alipay and others), covering merchant configuration, certificate encryption, callback signature verification, order lookup and refund reconciliation. New channels come online from the admin console — fill in the merchant ID, upload certs, select endpoints, enable.
A unified request-object abstraction handles all providers identically — adding a new third-party endpoint only requires registering its request and callback shape, with no need to re-walk each provider's raw documentation.
