Hyperswitch Prism’s low-level design example keeps processor-specific API behavior behind connector implementations while reusing a common payment-request flow. In aveeJ’s 2026 article, a unified Rust request is mapped to a selected processor’s request format, assembled through shared orchestration, and translated back into a unified response. The example is useful for understanding the design boundaries; it is condensed code, not a live payment integration.
What Prism’s design is trying to separate
The article presents Prism as a stateless Rust library that turns one unified payment request into a processor-specific API call. Its author says Prism supports 100+ connectors; that is an author-published figure from 2026, not an independently verified count or benchmark.
The central design choice is to separate what differs by processor from what can be shared. A connector supplies processor-specific behavior and transformations. Common orchestration can then select a connector, build a request, and normalize the response without placing every processor’s API rules in one large flow.

PaymentRequestrepresents the payment in a unified form rather than in one processor’s schema. - Select a connector. A factory maps a runtime connector enum to a concrete implementation. The article notes that this enum-to-implementation match is technically a simple factory, not the Gang of Four Factory Method pattern in its strict textbook sense.
- Apply connector behavior through a shared contract. The Strategy interface lets the chosen connector provide details such as its HTTP method and URL.
- Translate and validate the request. A request adapter converts the unified payment input into the processor-specific request shape and validates it.
- Assemble the outbound request through shared steps. A Template Method describes the common request-building sequence, while a Builder assembles the request.
- Normalize the result. A response adapter maps processor-specific status and transaction fields into a unified response.
In pattern terms, the article names Singleton, simple factory (with the Factory Method terminology caveat), Strategy, request and response Adapters, Template Method, and Builder. These labels matter less than the boundaries they describe: selection, processor-specific behavior, translation, and shared assembly each have a defined role.

What happens when adding a connector
For its Stripe example, the article shows the connector providing its HTTP method and base URL. A complete connector also needs request and response adapters, plus an enum variant and factory arm so the runtime can select it.
In the example, the shared payment representation, template method, builder, and orchestration function do not need to change. That is the intended extension point: add processor-specific behavior behind the existing contract and reuse the common path. It is not a guarantee that every real-world integration can be added without changes elsewhere; processor requirements may expose needs the example does not cover.
Rank #2
What the code sample demonstrates—and what it does not
The article identifies its code as a condensed reference version. In particular, the sample calls Adyen adapters directly and mocks the HTTP call. The article contrasts this with Prism’s connectors, which own their transformations, and says the real codebase sends the request over the wire.

How to assess this architecture in practice
The example offers a useful set of design questions for a connector library, rather than measured proof that one architecture is superior:
- Where does processor-specific behavior live, and can it be understood without tracing a large shared flow?
- When a connector is added, which parts are new, and which common orchestration steps remain unchanged?
- How are processor request and response schemas translated to and from the shared representation?
- Is connector registration explicit, and are selection and unsupported-connector cases handled clearly?
Those questions help distinguish a reusable connector boundary from a design that merely hides processor-specific branches behind pattern names. The article explains the intended structure, but does not provide comparative measurements, integration-time data, error rates, or performance benchmarks.
