1. SDK Integration Steps - iOS Ola Money

You can integrate with OlaMoney either using Cocoapods or manually.

Cocoapods Integration

The recommended procedure to include the PayUOlaMoneySDK in your iOS app is through Cocoapods. To include the framework in your Xcode project, add the following line to your Podfile:

Swift 5.1

pod 'PayUIndia-OlaMoney', '1.0.0'

Swift 5.1.3

pod 'PayUIndia-OlaMoney', '1.0.1'

Manual integration

If you do not want to use Cocoapods, download the framework manually and integrate it into your mobile app. To integrate manually, please follow the steps below:

1. Download the framework files from the following location: https://github.com/payu-intrepos/payu-olamoney-ios/
2. Link the framework from your Xcode project

Dependencies

The PayUOlaMoneySDK framework requires the following dependencies. When integrating through Cocoapods, these dependencies are added automatically, and you do not need to take any additional action.

If you are integrating with the PayUOlaMoneySDK manually, you will need to include the dependencies mentioned below. To include the frameworks manually, refer to the following PayU Github link: https://github.com/payu-intrepos/payu-upi-ios-sdk/tree/master/Dependencies

1. PayU Networking: This is used by PayUOlaMoneySDK to handle network requests.
2. PayU Logger: This is used by PayUOlaMoneySDK to log errors and verbose data.

To integrate with OlaMoney:

1. Set environment to Test or Production.

PayUOMCore.shared.environment = .production // PayUOMCore.shared.environment = .test

2. Set Logger level to verbose, error, or disabled.

PayUOMCore.shared.logLevel = .verbose // PayUOMCore.shared.logLevel = .none

3. Set mandatory payment parameters required for the payment.

do {
paymentParams = try PayUOMPaymentParams(
merchantKey: <Your merchant Key>, //Your merchant key for the environment set in step 1
transactionId: String.randomString(length: 10), //A unique ID for this trasaction
amount: "1", //Amount of transaction
productInfo: "iPhone", // Description of the product
firstName: "John", lastName: "Doe", // First name of the user
email: "[email protected]",// Email of the useer
phoneNumber: phoneNumberTextField.text ?? "9876543210", // Phone of user
//User defined parameters.
//You can save additional details for each transaction if you need them for your business logic.
//You will get these details back in payment response and transaction verify API
//Like, you can add SKUs for which payment is made.
udf1: "SKU1|SKU2|SKU3",
//You can keep all udf fields blank if you do not have any requirement to save txn specific data
udf2: "asdf",
udf3: "asdf",
udf4: "asdf",
udf5: "asdf")
// Example userCredentials - "merchantKey:user'sUniqueIdentifier"
paymentParams?.userCredentials = "smsplus:[email protected]"
// Success URL. Not used but required due to mandatory check.
paymentParams?.surl = "https://cbjs.payu.in/sdk/success"
// Failure URL. Not used but required due to mandatory check.
paymentParams?.furl = "https://cbjs.payu.in/sdk/failure"
paymentParams?.offerKey = "cardnumber@8370,cardnumbers2@8380,for particular bins@8427,srioffer@8428,cc2@8429"
} catch let error {
//Helper.showAlert("Could not create post params due to: \(error.localizedDescription)", onController: self)
}

4. Fetch hashes and save them in the paymentParams object
   • You need to set the hashes property in paymentParams. Hashes ensure that requests are untampered. This helps in ensuring the security of the transaction. Property hashes are of the type PayUOMHashes.

📘

Note

Hashes must be generated only on your server. Your secret key (also known as salt) must never be included in your app.For more information, refer to Hash Generation.

• PayUHashes has two properties. Each of these three is used for a distinct API call. The two properties are as follows:
  paymentHash: This is required to create transactions at PayU’s end.
  eligibilityHash: This is required by the checkEligibility API to check eligibility if user is eligible/registered for the Ola Money
• You need to provide hashes before asking SDK to initiate the payment and check the user’s eligibility.
• Command and var1 values for generating paymentRelatedDetailsForMobileSDKHash and validateVPAHash as defined in the following table:

5. After setting the value of hashes in paymentParams, call the following method of the PayUOMCore class to check whether the user is eligible to pay through Ola Money (Postpaid and Wallet):

public func checkEligibility(params: PayUOMPaymentParams, completion:@escaping(_ status: Bool, _ response: PayUOMEligibilityModel?, _ error: Error?) -> Void)

6. You will get a response of the type Result with the value of type PayUOMEligibilityModel in the response’s success param. The sample code snippet is similar to the following:

PayUOMCore.shared.checkEligibility(params: self.paymentParams!, completion: { [unowned self] status, response, error in
DispatchQueue.main.async {
self.makePaymentButton.isEnabled = status
if (error != nil) {
self.elegebilityLabel.text = error?.localizedDescription
} else {
self.elegebilityLabel.text = response?.msg
}
}
})

7. Populate the relevant options on your checkout screen.
8. Check the eligibility and fetch the post parameters with the method. Later, you can use the CustomBrowser or WKWebView to load the URL and PostData.

public func getPostData(params: PayUOMPaymentParams) -> String

9. Use the Custom Browser to load data using the following code (Optional):

let customBrowser = try? PUCBWebVC(postParam: postData, url: PayUOMSecureEndPoint.securePayment().baseURL, merchantKey: "smsplus")
customBrowser?.cbWebVCDelegate = self
let navVC = UINavigationController(rootViewController: customBrowser!)
self.present(navVC, animated: true, completion: nil)
