Installation

Node

Install the dependency using npm:

npm i https://phonepe.mycloudrepo.io/public/repositories/phonepe-pg-sdk-node/releases/v2/phonepe-pg-sdk-node.tgz

Quick Start

Initialization

Before using the SDK, you need to acquire your credentials from the PhonePe Merchant Portal.

You need three key pieces of information:

1. clientId - Your merchant identifier
2. clientSecret - Your authentication secret
3. clientVersion - API version to use

import {StandardCheckoutClient, Env} from 'pg-sdk-node';
 
const clientId = "<clientId>";
const clientSecret = "<clientSecret>";
const clientVersion = 1;        //insert your client version here
const env = Env.SANDBOX;        //change to Env.PRODUCTION when you go live
 
const client = StandardCheckoutClient.getInstance(clientId, clientSecret, clientVersion, env);

Standard Checkout Flow

To initiate a payment, create a request using StandardCheckoutPayRequest.builder():

import {StandardCheckoutPayRequest} from 'pg-sdk-node';
import {randomUUID} from 'crypto';
  
const merchantOrderId = randomUUID();
const amount = 100;
const redirectUrl = "https://www.merchant.com/redirect";
  
const request = StandardCheckoutPayRequest.builder()
        .merchantOrderId(merchantOrderId)
        .amount(amount)
        .redirectUrl(redirectUrl)
        .build();
  
client.pay(request).then((response)=> {
    const checkoutPageUrl = response.redirectUrl;
    console.log(checkoutPageUrl);
})

// Redirect the user to checkoutPageUrl to complete the payment

Checking Order Status

To check the status of an order:

const merchantOrderId = '<MERCHANT_ORDER_ID>';        //Order Id used for creating new order
 
client.getOrderStatus(merchantOrderId).then((response) => {
  const state = response.state;
});

// Handle the state accordingly in your application

Handling Callbacks

PhonePe sends callbacks to your configured endpoint. Validate these callbacks to ensure they're authentic:

const authorizationHeaderData = "<FETCH_SHA_256_DATA_FROM_HEADER>" // received in the response headers
const phonepeS2SCallbackResponseBodyString = "{\"type\": \"PG_ORDER_COMPLETED\",\"payload\": {}}"  // receiver in response body
  
const usernameConfigured = "<MERCHANT_USERNAME>"
const passwordConfigured = "<MERCHANT_PASSWORD>" 
 
try {
    const callbackResponse = client.validateCallback(
        usernameConfigured,
        passwordConfigured,
        authorizationHeaderData,
        phonepeS2SCallbackResponseBodyString );
    
    const orderId = callbackResponse.payload.orderId;
    const state = callbackResponse.payload.state;

    // Process the order based on its state
} catch (err) {
    // Handle invalid callback - potential security issue
}

SDK Order Integration

For mobile SDK integration, first create an order on your server:

import {StandardCheckoutClient, Env, CreateSdkOrderRequest} from 'pg-sdk-node';
import {randomUUID} from 'crypto';
 
const clientId = "<clientId>";
const clientSecret = "<clientSecret>";
const clientVersion = 1;  //insert your client version here
const env = Env.SANDBOX;      //change to Env.PRODUCTION when you go live
 
const client = StandardCheckoutClient.getInstance(clientId, clientSecret, clientVersion, env);
 
const merchantOrderId = randomUUID();
const amount = 1000;
const redirectUrl = "https://redirectUrl.com";
 
const request = CreateSdkOrderRequest.StandardCheckoutBuilder()
        .merchantOrderId(merchantOrderId)
        .amount(amount)
        .redirectUrl(redirectUrl)
        .build();
 
client.createSdkOrder(request).then((response) => {
    const token = response.token
})

// Pass this token to your mobile app to initiate payment through the PhonePe SDK
