What is Prism?

Prism is a stateless, unified connector library to connect with any payment processor. It is extracted out of the hardened integrations through continuous testing & iterative bug fixing over years of usage within Juspay Hyperswitch.

Why are payment processor integrations such a big deal?

Every payment processor has diverse APIs, error codes, authentication methods, pdf documents to read, and behavioural differences between the actual environment and documented specs.

A small mistake or oversight can create a huge financial impact for businesses accepting payments. Thousands of enterprises around the world have gone through this learning curve and iterated and fixed payment systems over many years. All such fixes/improvements/iterations are locked-in as tribal knowledge into Enterprise Payment Platforms and SaaS Payment Orchestration solutions.

Hence, Prism - to open up payment diversity to the entire world as a simple, lightweight, zero lock-in, developer friendly payments library.

Prism is extracted, built and maintained by the team behind Juspay Hyperswitch - the open-source payments platform with 40K+ Github stars and used by leading enterprise merchants around the world.

Note: In all honesty, payments are not more complicated than database drivers. It is simply just that the industry has not arrived at a standard (and it never will!!).

What does Prism do well?

• One request schema for every payment. The same authorize call works against Stripe, Adyen and many more without additional lines of code.
• Stateless. No database, no stored PII. Credentials are not stored/ logged by the library. It lives only up to the lifetime of your HTTP client.
• PCI scope reduction. The card data flowing/ not flowing into the library is your choice. You can choose to leverage any payment processor vault or your own PCI certified vault. Nothing is logged or stored by the library.

Integrations - Status

Prism supports multiple connectors with varying levels of payment method and flow coverage. Each connector is continuously tested against real sandbox/ production environments.

Legend: ✓ Supported | x Not Supported | ⚠ In Progress | ? Needs Validation

Status	Description
✓	Fully implemented and tested
x	Not applicable or unsupported by processor
⚠	Implementation in progress or partial
?	Implementation needs validation against live environment

What Prism does not do (yet)?

• Built-in vault or tokenization service. This is a design choice. You may bring your own vault, or use the payment processor's vault.
• Retry or routing logic. It lives in Juspay Hyperswitch. Prism is only the transformation layer.
• Beyond payments. The diversity exists beyond payments - in subscriptions, fraud, tax, payouts. And it is our aspiration, to evolve Prism into a stateless commerce library.

Make a Payment

Node.js

import { PaymentClient, types, IntegrationError, ConnectorError } from 'hyperswitch-prism';

let config: types.ConnectorConfig = {
    connectorConfig: {
        stripe: {
            apiKey: { value: "sk_test_" }
        }
    }
}

const main = async () => {
    try {
        let client = new PaymentClient(config)
        let request: types.PaymentServiceAuthorizeRequest = {
            merchantTransactionId: "authorize_123",
            amount: {
                minorAmount: 1000, // \$10.00
                currency: types.Currency.USD,
            },
            captureMethod: types.CaptureMethod.AUTOMATIC,
            paymentMethod: {
                card: {
                    cardNumber: { value: "4111111111111111" },
                    cardExpMonth: { value: "12" },
                    cardExpYear: { value: "2050" },
                    cardCvc: { value: "123" },
                    cardHolderName: { value: "Test User" },
                },
            },
            authType: types.AuthenticationType.NO_THREE_DS,
            address: {},
            orderDetails: [],
        }
        let response: types.PaymentServiceAuthorizeResponse = await client.authorize(request);
        switch (response.status) {
            case types.PaymentStatus.CHARGED:
                console.log("success");
                break;
            default:
                console.error("failed");
        }
    } catch (e: any) {
        //handle error
    }
  }

main()

This file contains complete SDK documentation including installation, payment operations, error handling, connector configuration, field probe data, and examples for all payment processors.

🔄 Routing between Payment Providers

Once the basic plumbing is implemented you can leverage Prism's core benefit - switch payment providers by changing one line.

  // Routing rule: EUR -> Adyen, USD -> Stripe
  const currency = types.Currency.USD;

  let stripeConfig: types.ConnectorConfig = {
      connectorConfig: {
          stripe: {
              apiKey: { value: process.env.STRIPE_API_KEY! }
          }
      }
  }

  let adyenConfig: types.ConnectorConfig = {
      connectorConfig: {
          adyen: {
              apiKey: { value: process.env.ADYEN_API_KEY! },
              merchantAccount: { value: process.env.ADYEN_MERCHANT_ACCOUNT! }
          }
      }
  }

  const config = currency === types.Currency.EUR ? adyenConfig : stripeConfig;
  const client = new PaymentClient(config);

  // Authorize call from previous step

You may just swap the client with any business rules and smart retry logic for payment processor routing. Each flow uses the same unified schema regardless of the underlying processor's API differences.

If you wish to learn more about routing logic and smart retries, you can checkout intelligent routing and smart retries. It can help configure and manage diverse payment acceptance setup, as well as improve conversion rates.

🛠️ Development

Prerequisites

• Rust 1.70+
• Protocol Buffers (protoc)

Building from Source

# Clone the repository
git clone https://github.com/juspay/hyperswitch-prism.git
cd hyperswitch-prism

# Build
cargo build --release

# Run tests
cargo test

Grace workspace (TypeScript dashboard + checkpoint engine)

For the grace/ TypeScript workspace (parity dashboard, AI-assisted connector integration), bootstrap with:

make grace-workspace

This auto-installs pnpm via corepack if needed, then runs the full prereq probe, install, build, and interactive .env scaffold. See grace/grace-workspace/README.md for the full setup story including LLM auth modes (Anthropic OAuth, bare API key, LiteLLM gateway) and runner choice (claude-code vs opencode).

Don't want Node + claude + gh on your host? Use the containerized path instead: make grace-workspace-docker builds a self-contained image and starts the supervisor + dashboard + opencode-serve sidecar via docker-compose. Requires TENXGRACE_PROJECT_ROOT exported. Full prereqs and limitations in the workspace README's "Docker (alternative entry)" section.
