❗️
Before you begin

To download iOS SDK through CocoaPod, refer to CocoaPods Integration.

Run the sample app:
i. Download latest SDK version and unzip it.
ii. Unzip Release-Universal, now drag and drop the content of unzipped file into Sample App

Step 1: Initial setup

To perform the initial setup:

Download the latest SDK version from the following location and unzip it: https://github.com/payu-intrepos/iOS-SDK/releases
Unzip Release-Universal, drag and drop the content of the unzipped file into Sample App.

#import <PayUBizCoreKit/PayUBizCoreKit.h>

Note: While working with the Swift project add the above code in Bridging-Header.h file.

Get all the required parameters.
Create an object of PayUModelPaymentParams and set all the parameters in it.

  @property (strong, nonatomic) PayUModelPaymentParams *paymentParamForPassing;
  self.paymentParamForPassing = [PayUModelPaymentParams new];
  self.paymentParamForPassing.key = @"0MQaQP";
  self.paymentParamForPassing.transactionID = @"Ywism0Q9XC88qvy";
  self.paymentParamForPassing.amount = @"10.0";
  self.paymentParamForPassing.productInfo = @"Nokia";
  self.paymentParamForPassing.firstName = @"Ram";
  self.paymentParamForPassing.email = @"[email protected]";
  self.paymentParamForPassing.userCredentials = @"ra:ra";
  self.paymentParamForPassing.phoneNumber = @"1111111111";
  self.paymentParamForPassing.SURL = @"https://payu.herokuapp.com/ios_success";
  self.paymentParamForPassing.FURL = @"https://payu.herokuapp.com/ios_failure";
  self.paymentParamForPassing.udf1 = @"u1";
  self.paymentParamForPassing.udf2 = @"u2";
  self.paymentParamForPassing.udf3 = @"u3";
  self.paymentParamForPassing.udf4 = @"u4";
  self.paymentParamForPassing.udf5 = @"u5";
  self.paymentParamForPassing.environment= ENVIRONMENT_PRODUCTION;
  self.paymentParamForPassing.offerKey = @"offertest@1411";
//You don't need to set udf1-5 in case you are not using them email and firstname can be empty strings "" if you don't want to use them For store user card feature you need to set userCredentials

let paymentParamForPassing = PayUModelPaymentParams()
paymentParamForPassing.key = "0MQaQP"
paymentParamForPassing.transactionID = "Ywism0Q9XC88qvy"
paymentParamForPassing.amount = "10.0"
paymentParamForPassing.productInfo = "Nokia"
paymentParamForPassing.firstName = "Ram"
paymentParamForPassing.email = "[email protected]"
paymentParamForPassing.userCredentials = "ra:ra"
paymentParamForPassing.phoneNumber = "1111111111"
paymentParamForPassing.surl = "https://payu.herokuapp.com/ios_success"
paymentParamForPassing.furl = "https://payu.herokuapp.com/ios_failure"
paymentParamForPassing.udf1 = "u1"
paymentParamForPassing.udf2 = "u2"
paymentParamForPassing.udf3 = "u3"
paymentParamForPassing.udf4 = "u4"
paymentParamForPassing.udf5 = "u5"
paymentParamForPassing.environment = ENVIRONMENT_PRODUCTION
paymentParamForPassing.offerKey = "offertest@1411"

Note: You don’t need to set the udf1 – udf5 parameters. In case you are not using them, the email and firstname parameters can be empty strings (“”).

Set paymentParamForPassing.userCredentials to store the user card:

  self.paymentParamForPassing.userCredentials = @"ra:ra"

paymentParamForPassing.userCredentials = "ra:ra"

Set offerKey for offers:

  self.paymentParamForPassing.offerKey = @"offertest@1411"

paymentParamForPassing.offerKey = "offertest@1411"

Set default param (like phone and others) for any other payment:

self.paymentParamForPassing.phoneNumber = @"1111111111";

paymentParamForPassing.phoneNumber = "1111111111"

Get the required hashes by using your own server. Set the hashes as follows:

  self.paymentParamForPassing.hashes.paymentHash = @"ade84bf6dd9da35d0aab50a5bf61d6272ab0fc488b361b65c66745054aacf1900e3c60b5022d2114bae7360174ebcb3cd7185a5d472e5c99701e5e7e1eccec34";

Step 2: Generate URL request for payment

To generate an URL request (and post parameters), you need to create an object as createRequest of the PayUCreateRequest class as shown in the following code block:

@property (nonatomic, strong) PayUCreateRequest *createRequest;

let createRequest = PayUCreateRequest()

The callbacks give your URLRequest as well as post parameters (NSString format). You can use these post parameters to initialize the Custom Browser Instance.

The following payment types are supported by SDK, and additional parameters are supported. The additional parameters that can be configured in the createRequest object created earlier are described in this section.

Credit Card/Debit Card

To pay using a credit card or debit card, perform the following steps.

Set the following credit card parameters:

        self.paymentParamForPassing.cardNumber = @"5123456789012346";//cardNumber
        self.paymentParamForPassing.nameOnCard = @"name";//Name on card
        self.paymentParamForPassing.expYear = @"2018";//Expiry year
        self.paymentParamForPassing.expMonth = @"11";//ExpiryMonth
        self.paymentParamForPassing.CVV = @"123";//CVV
        self.paymentParamForPassing.storeCardName = @"My TestCard";//If you want to save card then pass StoreCardName otherwise it will not save & make sure userCredentials are provided

paymentParamForPassing.cardNumber = "5123456789012346" //cardNumber
paymentParamForPassing.nameOnCard = "name" //Name on card
paymentParamForPassing.expYear = "2018" //Expiry year
paymentParamForPassing.expMonth = "11" //ExpiryMonth
paymentParamForPassing.cvv = "123" //CVV
paymentParamForPassing.storeCardName = "My TestCard" //If you want to save card then pass StoreCardName otherwise it will not save & make sure userCredentials are provided

Get the request by using the createRequestWithPaymentParam method as follows:

        self.createRequest = [PayUCreateRequest new];
        [self.createRequest createRequestWithPaymentParam:self.paymentParamForPassing forPaymentType:PAYMENT_PG_CCDC withCompletionBlock:^(NSMutableURLRequest *request, NSString *postParam, NSString *error) {
        if (error == nil) {
        //It is good to go state. You can use request parameter in webview to open Payment Page
        }
        else{
        //Something went wrong with Parameter, error contains the error Message string
        }
    }];

createRequest().createRequest(withPaymentParam: paymentParamForPassing, forPaymentType: PAYMENT_PG_CCDC, withCompletionBlock: { request, postParam, error in
    if error == nil {
        //It is good to go state. You can use request parameter in webview to open Payment Page
    } else {
        //Something went wrong with Parameter, error contains the error Message string
    }
})

Stored Card

To Pay using StoredCard, perform the following steps.

Set the StoredCard parameter similar to the following code snippet:

    PayUModelStoredCard *modelStoredCard = [self.paymentRelatedDetail.storedCardArray objectAtIndex:indexPath.row];

    self.paymentParamForPassing.cardToken = modelStoredCard.cardToken;
    self.paymentParamForPassing.cardBin = modelStoredCard.cardBin;
    self.paymentParamForPassing.CVV = @"123";//CVV

let modelStoredCard = paymentRelatedDetail.storedCardArray[indexPath.row] as? PayUModelStoredCard

paymentParamForPassing.cardToken = modelStoredCard?.cardToken
paymentParamForPassing.cardBin = modelStoredCard?.cardBin
paymentParamForPassing.cvv = "123" //CVV

Get the request by using thecreateRequestWithPaymentParam method similar to the following code snippet:

createRequest.createRequest(withPaymentParam: paymentParamForPassing, forPaymentType: PAYMENT_PG_STOREDCARD, withCompletionBlock: { request, postParam, error in
    if error == nil {
        //It is good to go state. You can use request parameter in webview to open Payment Page
    } else {
        //Something went wrong with Parameter, error contains the error Message string
    }
})

    self.createRequest = [PayUCreateRequest new];
    [self.createRequest createRequestWithPaymentParam:self.paymentParamForPassing forPaymentType:PAYMENT_PG_STOREDCARD withCompletionBlock:^(NSMutableURLRequest *request, NSString *postParam, NSString *error) {
    if (error == nil) {
    //It is good to go state. You can use request parameter in webview to open Payment Page
    }
    else{
    //Something went wrong with Parameter, error contains the error Message string
    }
}];

Tokenization

For cards tokenized outside the PayU platform merchant needs to pass the parameters similar to the following code block:

    self.paymentParam.cardTokenType = @"1";
    self.paymentParam.additionalInfo = [[AdditionalInfo alloc] initWithLast4Digits:@"1234" tavv:@"1234" trid:@"1234" tokenRefNo:@"1234"];

paymentParam.cardTokenType = "1"
paymentParam.additionalInfo = AdditionalInfo(last4Digits: "1234", tavv: "1234", trid: "1234", tokenRefNo: "1234")

After setting the above parameters, you can get the request by using thecreateRequestWithPaymentParam.

Net Banking

To pay using NetBanking, perform the following steps.

Set the NetBanking parameter as follows:

paymentParamForPassing.bankCode = "AXIB" //BankCode

Get the request by using the createRequestWithPaymentParam method as follows:

    self.createRequest = [PayUCreateRequest new];

    if (error == nil) {
    //It is good to go state. You can use request parameter in webview to open Payment Page
    }
    else{
    //Something went wrong with Parameter, error contains the error Message string
    }
}];

createRequest.createRequest(withPaymentParam: paymentParamForPassing, forPaymentType: PAYMENT_PG_NET_BANKING, withCompletionBlock: { request, postParam, error in
if error == nil {
//It is good to go state. You can use request parameter in webview to open Payment Page

       if (error == nil) {
          //It is good to go state. You can use request parameter in webview to open Payment Page
       }
       else{
         //Something went wrong with Parameter, error contains the error Message string
       }
    }];

createRequest.createRequest(withPaymentParam: paymentParamForPassing, forPaymentType: PAYMENT_PG_CASHCARD, withCompletionBlock: { request, postParam, error in
