Payment Gateway: One API, Multiple PSPs

Facilitate seamless and secure online payments. The Payment Gateway microservice provides a common abstraction over payment service providers, so you can accept payments and manage transactions through one API.

Before you connect real money: PSP webhook signature verification is incomplete. Do not connect Payment Gateway to live funds until this is resolved — treat any current deployment as sandbox-only for payment flows.

Eliminate Vendor Lock-In

Don't tie your core business logic to a single payment processor. Payment Gateway's PSP abstraction (SPI) lets you add a new provider as a self-contained module — implementing PaymentProvider and, optionally, ProviderCheckoutSupport / ProviderWebhookSupport — without changing existing code, and standardizes webhook handling across whichever providers you add.

Unified Abstraction & Webhook Normalization

A single RESTful API for one-time and recurring payments. The gateway automatically translates proprietary PSP webhooks into standardized internal events for your ecosystem.

Idempotent Payments & Secure Handling

Idempotent, distributed-lock-backed payment processing means retries never double-charge. Works in tandem with the Auth Gateway to ensure all payment requests are strictly authenticated and authorized at the edge.
