Payram Checkout Integration

SDK Integration (Node.js/TypeScript)

Install SDK

npm install payram dotenv

Create Payment with SDK

import { Payram, InitiatePaymentRequest, InitiatePaymentResponse, isPayramSDKError } from 'payram';

const payram = new Payram({
  apiKey: process.env.PAYRAM_API_KEY!,
  baseUrl: process.env.PAYRAM_BASE_URL!,
  config: {
    timeoutMs: 10_000,
    maxRetries: 2,
    retryPolicy: 'safe',
    allowInsecureHttp: false,
  },
});

export async function createCheckout(
  payload: InitiatePaymentRequest,
): Promise<InitiatePaymentResponse> {
  try {
    const checkout = await payram.payments.initiatePayment(payload);
    console.log('Redirect customer to:', checkout.url);
    console.log('Payment reference:', checkout.reference_id);
    return checkout;
  } catch (error) {
    if (isPayramSDKError(error)) {
      console.error('Payram Error:', {
        status: error.status,
        requestId: error.requestId,
        retryable: error.isRetryable,
      });
    }
    throw error;
  }
}

// Example usage
await createCheckout({
  customerEmail: '[email protected]',
  customerId: 'cust_123',
  amountInUSD: 49.99,
});

Required Fields:

• customerEmail: Customer's email address
• customerId: Your internal customer identifier
• amountInUSD: Payment amount in USD

Optional Fields:

• settlementCurrency: Currency for settlement (default: USD)
• memo: Internal reference or description
• redirectUrl: Custom URL to redirect after payment

Check Payment Status with SDK

import { Payram, PaymentRequestData, isPayramSDKError } from 'payram';

const payram = new Payram({
  apiKey: process.env.PAYRAM_API_KEY!,
  baseUrl: process.env.PAYRAM_BASE_URL!,
});

export async function getPaymentStatus(referenceId: string): Promise<PaymentRequestData> {
  try {
    const payment = await payram.payments.getPaymentRequest(referenceId);
    console.log('Latest payment state:', payment.paymentState);
    console.log('Amount paid:', payment.amountPaid);
    console.log('Transaction hash:', payment.transactionHash);
    return payment;
  } catch (error) {
    if (isPayramSDKError(error)) {
      console.error('Payram Error:', {
        status: error.status,
        errorCode: error.error,
        requestId: error.requestId,
      });
    }
    throw error;
  }
}

HTTP Integration (Python, Go, PHP, Java)

API Endpoint

POST https://your-payram-server:8080/api/v1/payment
Header: API-Key: your-api-key
Content-Type: application/json

Critical: PayRam uses API-Key header, NOT Authorization: Bearer.

Request Body:

{
  "customerEmail": "[email protected]",
  "customerId": "user_12345",
  "amountInUSD": 25
}

Response:

{
  "host": "https://your-payram-server:8080",
  "reference_id": "c80f5363-0397-4761-aa1a-3155c3a21470",
  "url": "https://your-payram-server/payments?reference_id=..."
}

Python (FastAPI)

import httpx
import os
from fastapi import APIRouter
from fastapi.responses import RedirectResponse

PAYRAM_BASE_URL = os.environ['PAYRAM_BASE_URL']
PAYRAM_API_KEY = os.environ['PAYRAM_API_KEY']

@router.post("/create-payment")
async def create_payment(email: str, user_id: str, amount: float):
    async with httpx.AsyncClient() as client:
        resp = await client.post(
            f"{PAYRAM_BASE_URL}/api/v1/payment",
            json={"customerEmail": email, "customerId": user_id, "amountInUSD": amount},
            headers={"API-Key": PAYRAM_API_KEY}
        )
    return RedirectResponse(resp.json()["url"])

Go (Gin)

func CreatePayment(email, customerID string, amount float64) (*InitiatePaymentResponse, error) {
    body, _ := json.Marshal(map[string]interface{}{
        "customerEmail": email,
        "customerId":    customerID,
        "amountInUSD":   amount,
    })

    url := fmt.Sprintf("%s/api/v1/payment", os.Getenv("PAYRAM_BASE_URL"))
    req, _ := http.NewRequest(http.MethodPost, url, bytes.NewBuffer(body))
    req.Header.Set("Content-Type", "application/json")
    req.Header.Set("API-Key", os.Getenv("PAYRAM_API_KEY"))

    resp, err := http.DefaultClient.Do(req)
    // ... handle response
}

PHP (Laravel)

$ch = curl_init(getenv('PAYRAM_BASE_URL') . '/api/v1/payment');
curl_setopt_array($ch, [
    CURLOPT_POST => true,
    CURLOPT_HTTPHEADER => [
        'Content-Type: application/json',
        'API-Key: ' . getenv('PAYRAM_API_KEY'),
    ],
    CURLOPT_POSTFIELDS => json_encode($payload),
    CURLOPT_RETURNTRANSFER => true,
]);

Java (Spring Boot)

HttpRequest request = HttpRequest.newBuilder()
    .uri(URI.create(baseUrl + "/api/v1/payment"))
    .header("Content-Type", "application/json")
    .header("API-Key", apiKey)
    .POST(HttpRequest.BodyPublishers.ofString(payload))
    .build();

Framework Route Examples

Express.js Route

import { Router } from 'express';
import { Payram, InitiatePaymentRequest, isPayramSDKError } from 'payram';

const router = Router();
const payram = new Payram({
  apiKey: process.env.PAYRAM_API_KEY!,
  baseUrl: process.env.PAYRAM_BASE_URL!,
});

router.post('/api/payments/payram', async (req, res) => {
  const payload = req.body as Partial<InitiatePaymentRequest>;

  if (!payload?.customerEmail || !payload.customerId || typeof payload.amountInUSD !== 'number') {
    return res.status(400).json({ error: 'MISSING_REQUIRED_FIELDS' });
  }

  try {
    const checkout = await payram.payments.initiatePayment({
      customerEmail: payload.customerEmail,
      customerId: payload.customerId,
      amountInUSD: payload.amountInUSD,
    });
    return res.status(201).json({
      referenceId: checkout.reference_id,
      checkoutUrl: checkout.url,
    });
  } catch (error) {
    if (isPayramSDKError(error)) {
      console.error('Payram Error:', { status: error.status, requestId: error.requestId });
    }
    return res.status(502).json({ error: 'PAYRAM_CREATE_PAYMENT_FAILED' });
  }
});

Next.js App Router

import { NextRequest, NextResponse } from 'next/server';
import { Payram, InitiatePaymentRequest, isPayramSDKError } from 'payram';

const payram = new Payram({
  apiKey: process.env.PAYRAM_API_KEY!,
  baseUrl: process.env.PAYRAM_BASE_URL!,
});

export async function POST(request: NextRequest) {
  const payload = (await request.json()) as Partial<InitiatePaymentRequest>;

  if (!payload?.customerEmail || !payload.customerId || typeof payload.amountInUSD !== 'number') {
    return NextResponse.json({ error: 'MISSING_REQUIRED_FIELDS' }, { status: 400 });
  }

  try {
    const checkout = await payram.payments.initiatePayment({
      customerEmail: payload.customerEmail,
      customerId: payload.customerId,
      amountInUSD: payload.amountInUSD,
    });
    return NextResponse.json({
      referenceId: checkout.reference_id,
      checkoutUrl: checkout.url,
    });
  } catch (error) {
    if (isPayramSDKError(error)) {
      console.error('Payram Error:', { status: error.status, requestId: error.requestId });
    }
    return NextResponse.json({ error: 'PAYRAM_CREATE_PAYMENT_FAILED' }, { status: 502 });
  }
}

Status Polling Pattern

async function pollPaymentStatus(referenceId: string, maxAttempts = 10) {
  for (let i = 0; i < maxAttempts; i++) {
    const payment = await getPaymentStatus(referenceId);

    if (payment.paymentState === 'FILLED' || payment.paymentState === 'OVER_FILLED') {
      return payment;
    }

    if (payment.paymentState === 'CANCELLED') {
      throw new Error(`Payment ${payment.paymentState.toLowerCase()}`);
    }

    if (payment.paymentState === 'UNDEFINED') {
      throw new Error('Payment status undefined');
    }

    await new Promise((resolve) => setTimeout(resolve, Math.min(1000 * Math.pow(2, i), 30000)));
  }

  throw new Error('Payment status check timeout');
}

Database Schema

CREATE TABLE payments (
    id SERIAL PRIMARY KEY,
    customer_id VARCHAR(255) NOT NULL,
    payram_reference_id VARCHAR(255) UNIQUE NOT NULL,
    amount_usd DECIMAL(10, 2) NOT NULL,
    status VARCHAR(50) DEFAULT 'OPEN',
    checkout_url TEXT NOT NULL,
    created_at TIMESTAMP DEFAULT NOW(),
    updated_at TIMESTAMP DEFAULT NOW()
);

CREATE INDEX idx_payram_reference ON payments(payram_reference_id);
CREATE INDEX idx_customer_id ON payments(customer_id);

MCP Server Code Generation

Use the PayRam MCP server to generate framework-specific code:

Environment Configuration

# .env
PAYRAM_BASE_URL=https://your-payram-server:8080
PAYRAM_API_KEY=your-api-key-here

Use generate_env_template MCP tool to scaffold this.
