Handy Tips

If you use M1 MacBook, you need to make the following changes in your podfile.

installer.pods_project.build_configurations.each do |config|
  config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
end

1.1 Create an Order in Server

Order is an important step in the payment process.

An order should be created for every payment.
You can create an order using the
Orders API
. It is a server-side API call. Know how to
authenticate
Orders API.
The order_id received in the response should be passed to the checkout. This ties the order with the payment and secures the request from being tampered.

API Sample Code

Use this endpoint to create an order using the Orders API.

POST

/orders

curl -X POST https://api.razorpay.com/v1/orders
-U [YOUR_KEY_ID]:[YOUR_KEY_SECRET]
-H 'content-type:application/json'
-d '{
   "amount": 100,
   "currency": "MYR",
   "receipt": "qwsaq1",
   "partial_payment": true,
   "first_payment_min_amount": 230,
   "notes": {
     "key1": "value3",
     "key2": "value2"
   }
 }'

1.2 Install Razorpay Cordova plugin

Handy Tips

Starting from 1.4.14, the cordova project is now available at

npmjs

. Use the code given below to install:

1.3 Add Checkout Code

Ionic

In your app's home.page.html file, add the following code. This code generates a button that your customer will click to open the Checkout and make the payment.
<ion-button (click)="payWithRazorpay()">
Pay With Razorpay
</ion-button>
In your app's home.page.ts file, import RazorpayCheckout as shown:

1.4 Store Fields in your Server

A successful payment returns the following fields to the Checkout form.

You need to store these fields in your server.
You can confirm the authenticity of these details by verifying the signature in the next step.

razorpay_payment_id

string Unique identifier for the payment returned by Checkout only for successful payments.

razorpay_order_id

string Unique identifier for the order returned by Checkout.

razorpay_signature

string Signature returned by the Checkout. This is used to verify the payment.

1.5 Verify Signature

This is a mandatory step to confirm the authenticity of the details returned to the Checkout form for successful payments.

To verify the razorpay_signature returned to you by the Checkout form:

Create a signature in your server using the following attributes:
- order_id: Retrieve the order_id from your server. Do not use the razorpay_order_id returned by Checkout.
- razorpay_payment_id: Returned by Checkout.
- key_secret: Available in your server. The key_secret that was generated from the
  Curlec Dashboard
  .

Use the SHA256 algorithm, the razorpay_payment_id and the order_id to construct a HMAC hex digest as shown below:

generated_signature = hmac_sha256(order_id + "|" + razorpay_payment_id, secret);

  if (generated_signature == razorpay_signature) {
    payment is successful
  }

If the signature you generate on your server matches the razorpay_signature returned to you by the Checkout form, the payment received is from an authentic source.

Generate Signature on Your Server

Given below is the sample code for payment signature verification:

RazorpayClient razorpay = new RazorpayClient("[YOUR_KEY_ID]", "[YOUR_KEY_SECRET]");


String secret = "EnLs21M47BllR3X8PSFtjtbd";


JSONObject options = new JSONObject();
options.put("razorpay_order_id", "order_IEIaMR65cu6nz3");
options.put("razorpay_payment_id", "pay_IH4NVgf4Dreq1l");
options.put("razorpay_signature", "0d4e745a1838664ad6c9c9902212a32d627d68e917290b0ad5f08ff4561bc50f");


boolean status =  Utils.verifyPaymentSignature(options, secret);

Post Signature Verification

After you have completed the integration, you can

set up webhooks

, make test payments, replace the test key with the live key and integrate with other

APIs

1.6 Android-specfic - Android Lifecycle Guide

It is recommended that you read the

Android Lifecycle Guide

before proceeding with this section.

Since our plugin launches a new activity on Android, the Cordova activity goes in the background and might get destroyed by the Android System.

Sample Code

To make sure the payment result is delivered after the activity is recreated, use the following code:

// You need to register an event listener for the `resume` event
document.addEventListener('resume', onResume, false);
var onResume = function(event) {
        // Re-register the payment success and cancel callbacks
        RazorpayCheckout.on('payment.success', successCallback)
        RazorpayCheckout.on('payment.cancel', cancelCallback)
        // Pass on the event to RazorpayCheckout
        RazorpayCheckout.onResume(event);
      };

1.7 Verify Payment Status

Handy Tips

On the Dashboard, ensure that the payment status is captured. Refer to the payment capture settings page to know how to

capture payments automatically

You can track the payment status in three ways:

To verify the payment status from the Dashboard:

Log in to the
Dashboard
and navigate to Transactions → Payments.
Check if a Payment Id has been generated and note the status. In case of a successful payment, the status is marked as Captured.

Check if the payment id is generated and the status is captured
