You can import the Razorpay iOS Standard SDK library using any of these ways:

  • Cocoapod
  • Manual
  • Objective-C.

Refer to our

(bitcode enabled) pod.

  1. Download the SDK and unzip it.
  2. Open your project in XCode and go to file under Menu. Select Add files to "yourproject".
  3. Select Razorpay.xcframework in the directory you just unzipped.
  4. Select the Copy items if needed checkbox.
  5. Click Add.
  6. Navigate to Target settings → General and add the Razorpay.xcframework in both Embedded Binaries and Linked Frameworks and Libraries.

If you are building an Objective-C project, follow the steps given for Swift and the additional steps given below:

  1. Go to Project Settings and select Build Settings - All and Combined.
  2. Set the Always Embed Swift Standard Libraries option to TRUE.

Ensure that you have the framework added in both Embedded Binaries and Linked Frameworks and Libraries under Target settings - General.

Ensure that you have the framework added in Frameworks, Libraries, and Embed Content under Target settings - General. Change Embed status from - Do not Embed to Embed & Sign.
Watch the GIF to see how to add Frameworks, Libraries and Embed Content.

add Frameworks, Libraries and Embed Content

To initialize Razorpay iOS Standard SDK, you need the following:

  • API keys. You can generate this from the

    .

    Watch Out!

    API keys should not be hardcoded in the app. Must be sent from your backend as app-related metadata fetch.

  • A delegate that implements RazorpayPaymentCompletionProtocol or RazorpayPaymentCompletionProtocolWithData.

Watch Out!

  • For Swift version 5.1+, ensure that you declare var razorpay: RazorpayCheckout!.
  • For versions lower than 5.1, use var razorpay: Razorpay!.
  • Alternatively, you can use the following alias and retain the variable as Razorpay.

typealias Razorpay = RazorpayCheckout

import Razorpay
class ViewController: UIViewController, RazorpayPaymentCompletionProtocol {
// typealias Razorpay = RazorpayCheckout
var razorpay: RazorpayCheckout!
override func viewDidLoad() {
super.viewDidLoad()
razorpay = RazorpayCheckout.initWithKey(razorpayTestKey, andDelegate: self)
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
self.showPaymentForm()
}
}

Order is an important step in the payment process.

  • An order should be created for every payment.
  • You can create an order using the . It is a server-side API call. Know how to 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.

You can create an order:

  • Using the sample code on the Razorpay Postman Public Workspace.
  • By manually integrating the API sample codes on your server.

You can use the Postman workspace below to create an order:

Handy Tips

Under the Authorization section in Postman, select Basic Auth and add the Key Id and secret as the Username and Password, respectively.

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

POST
/orders
curl -X POST https://api.razorpay.com/v1/orders

Request Parameters

amount

mandatory

integer Payment amount in the smallest currency sub-unit. For example, if the amount to be charged is ₹299.00, then pass 29900 in this field. In the case of three decimal currencies, such as KWD, BHD and OMR, to accept a payment of 295.991, pass the value as 295990. And in the case of zero decimal currencies such as JPY, to accept a payment of 295, pass the value as 295.

Watch Out!

As per payment guidelines, you should pass the last decimal number as 0 for three decimal currency payments. For example, if you want to charge a customer 99.991 KD for a transaction, you should pass the value for the amount parameter as 99990 and not 99991.

Provide your customers with a better payment experience by enabling UPI Intent on your app's Checkout form. In the UPI Intent flow:

  1. Customer selects UPI as the payment method in your iOS app. A list of UPI apps supporting the intent flow is displayed. For example, PhonePe, Google Pay and Paytm.
  2. Customer selects the preferred app. The UPI app opens with pre-populated payment details.
  3. Customer enters their UPI PIN to complete their transactions.
  4. Once the payment is successful, the customer is redirected to your app or website.

To enable this in your iOS integration, you must make the following changes in your app's info.plist file.

<key>LSApplicationQueriesSchemes</key>
<array>
<string>tez</string>
<string>phonepe</string>
<string>paytmmp</string>

Configure and initiate a recurring payment transaction on UPI Intent:

let options: [String:Any] = [
"key": "YOUR_KEY_ID",
"order_id": "order_DBJOWzybfXXXX",
"customer_id": "cust_BtQNqzmBlXXXX",
"prefill": [
"contact": "+919000090000",
"email": "gaurav.kumar@example.com"
],
"image": "https://spaceplace.nasa.gov/templates/featured/sun/sunburn300.png",
"amount": 10000, // Amount should match the order amount
"currency": "INR",
"recurring": 1 // This key value pair is mandatory for Intent Recurring Payment.
]

After completing payment, you can handle success or error events by implementing onPaymentSuccess and onPaymentError methods of the RazorpayPaymentCompletionProtocol.

Alternatively, you can implement onPaymentSuccess and onPaymentError methods of RazorpayPaymentCompletionProtocolWithData.

extension CheckoutViewController : RazorpayPaymentCompletionProtocol {
func onPaymentError(_ code: Int32, description str: String) {
print("error: ", code, str)
self.presentAlert(withTitle: "Alert", message: str)
}
func onPaymentSuccess(_ payment_id: String) {
print("success: ", payment_id)
self.presentAlert(withTitle: "Success", message: "Payment Succeeded")
}
}

extension CheckoutViewController: RazorpayPaymentCompletionProtocolWithData {
func onPaymentError(_ code: Int32, description str: String, andData response: [AnyHashable : Any]?) {
print("error: ", code)
self.presentAlert(withTitle: "Alert", message: str)
}
func onPaymentSuccess(_ payment_id: String, andData response: [AnyHashable : Any]?) {
print("success: ", payment_id)
self.presentAlert(withTitle: "Success", message: "Payment Succeeded")
}
}

After completing the payment, add necessary actions based on success or error events.

Failure Codes:

  • 0: Network error
  • 1: Initialization failure / Unexpected behaviour
  • 2: Payment cancelled by the user

Success handler receives payment_id that you can use later for capturing the payment.

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.

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:

  1. 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 .
  2. 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
    }
  3. 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.

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);

After you have completed the integration, you can

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

Handy Tips

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

.

You can track the payment status in three ways:

To verify the payment status from the Dashboard:

  1. Log in to the and navigate to TransactionsPayments.
  2. 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
