PayU Non-SeamLess IOS Integration

PAYU Non-SeamLess Integration in iOS

Prerequisites: 1 Add libz.tbd libraries into your project (Project->Build Phases->Link Binary With Libraries) 2 Add -ObjC and $(OTHER_LDFLAGS)in Other Linker Flags in Project Build Settings(Project->Build Settings->Other Linker Flags) 3 To run the app on iOS9, please add the below code in info.plist
NSAppTransportSecurity NSAllowsArbitraryLoads

Steps :

1. Download the PayU SDK and drag drop the PAYU folder into the Xcode project

2. In AppDelegate.h add the below property

@property (weak, nonatomic) UIViewController *paymentOptionVC;

2. Create a button in your View Controller to start payment on its action

3. Initialize the PayUModelPaymentParams with mandatary values in the action selector

Test Environment

Key : gtKFFx Salt : eCwWELxi

Production Environment

Key : Generate by Logining to PayU Money Portal Salt : Generate by Logining to PayU Money Portal

Note: Production key and salt can only be used if Account is activated by the merchant with all the details otherwise it may not give proper results

Sample :

_paymentParam = [[PayUModelPaymentParams alloc] init];

_paymentParam.key = Key;
_paymentParam.transactionID = [NSString stringWithFormat:@"%ld", arc4random() % 9999999999];
_paymentParam.amount = @"10";
_paymentParam.productInfo = @"iPhone";
_paymentParam.SURL = @"https://payu.herokuapp.com/success";
_paymentParam.FURL = @"https://payu.herokuapp.com/failure";
_paymentParam.firstName = @"Pulkit";
_paymentParam.email = [NSString stringWithFormat:@"pulkitarora%[email protected]", arc4random() % 9999999999];

// Set this property if you want to get the stored cards otherwise set as empty string:

In Production Mode: _paymentParam.userCredentials = [NSString stringWithFormat:@"%@:%@", Key, _paymentParam.email];

In Test Mode: _paymentParam.userCredentials = @“ra:ra”;

// Set any user defined values if U want otherwise set as empty string: _paymentParam.udf1 = @""; _paymentParam.udf2 = @""; _paymentParam.udf3 = @""; _paymentParam.udf4 = @""; _paymentParam.udf5 = @"";

// Set the environment according to merchant key ENVIRONMENT_PRODUCTION for Production & // ENVIRONMENT_TEST for test environment: _paymentParam.environment = ENVIRONMENT_MOBILEDEV;

// Set this property if you want to give offer:
_paymentParam.offerKey = @"";

// Set required hashes

PayUModelHashes *hashes = [PayUModelHashes new];

NSString *hashValue = [NSString stringWithFormat:@"%@|%@|%@|%@|%@|%@|||||||||||%@", params.key, params.transactionID, params.amount, params.productInfo, params.firstName, params.email, Salt];
NSString *hash = [self createSHA512:hashValue]; //Payment Hash
hashes.paymentHash = hash;

// hashValue = [NSString stringWithFormat:@"%@|%@|%@|%@", params.key, @"get_merchant_ibibo_codes", @"default", Salt]; // hash = [self createSHA512:hashValue]; //IBIBO hash

hashValue = [NSString stringWithFormat:@"%@|%@|%@|%@", params.key, @"vas_for_mobile_sdk", @"default", Salt];
hash = [self createSHA512:hashValue]; //VAS hash
hashes.VASForMobileSDKHash = hash;

if(params.userCredentials != nil && ![params.userCredentials  isEqual: @""])
{
    hashValue = [NSString stringWithFormat:@"%@|%@|%@|%@", params.key, @"delete_user_card", params.userCredentials, Salt];
    hash = [self createSHA512:hashValue]; //Delete User Card Hash
    hashes.deleteUserCardHash = hash;
    
    hashValue = [NSString stringWithFormat:@"%@|%@|%@|%@", params.key, @"get_user_cards", params.userCredentials, Salt];
    hash = [self createSHA512:hashValue]; //Delete User Card Hash
    hashes.getUserCardHash = hash;
    
    hashValue = [NSString stringWithFormat:@"%@|%@|%@|%@", params.key, @"edit_user_card", params.userCredentials, Salt];
    hash = [self createSHA512:hashValue]; //Delete User Card Hash
    hashes.editUserCardHash = hash;
    
    hashValue = [NSString stringWithFormat:@"%@|%@|%@|%@", params.key, @"save_user_card", params.userCredentials, Salt];
    hash = [self createSHA512:hashValue]; //Delete User Card Hash
    hashes.saveUserCardHash = hash;
    
    hashValue = [NSString stringWithFormat:@"%@|%@|%@|%@", params.key, @"payment_related_details_for_mobile_sdk", params.userCredentials, Salt];
    hash = [self createSHA512:hashValue]; //Payment Details Hash
    hashes.paymentRelatedDetailsHash = hash;
}

Note: For Security purpose generate these hashes on Server side and pass it to the client

_paymentParam.hashes = hashes;

// Function to generate SHA512 in Objective - C

-(NSString *)createSHA512:(NSString *)string { const char *cstr = [string cStringUsingEncoding:NSUTF8StringEncoding]; NSData data = [NSData dataWithBytes:cstr length:string.length]; uint8_t digest[CC_SHA512_DIGEST_LENGTH]; CC_SHA512(data.bytes, (CC_LONG)data.length, digest); NSMutableString output = [NSMutableString stringWithCapacity:CC_SHA512_DIGEST_LENGTH * 2]; for(int i = 0; i < CC_SHA512_DIGEST_LENGTH; i++) { [output appendFormat:@"%02x", digest[i]]; } return output; }

4. Add an Observer to Payment Service before initiating the Payment

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(responseReceived:) name:kPUUINotiPaymentResponse object:nil];

5. Call the Payment related details for mobile SDK function from PayU SDK with the instance of PayUModelPaymentParams

Sample Code:

PayUWebServiceResponse *webServiceResponse =[[PayUWebServiceResponse alloc]init]; [webServiceResponse getPayUPaymentRelatedDetailForMobileSDK:paymentParam withCompletionBlock:^(PayUModelPaymentRelatedDetail *paymentRelatedDetails, NSString *errorMessage, id extraParam) {

    if (!errorMessage) { UIStoryboard *stryBrd = [UIStoryboard storyboardWithName:@"PUUIMainStoryBoard" bundle:nil]; PUUIPaymentOptionVC * paymentOptionVC = [stryBrd instantiateViewControllerWithIdentifier:VC_IDENTIFIER_PAYMENT_OPTION];
        
        paymentOptionVC.paymentParam = paymentParam;
        paymentOptionVC.paymentRelatedDetail = paymentRelatedDetails;
        
        [self.navigationController pushViewController:paymentOptionVC animated:true];
    } else{
        // error occurred while creating the request
    }
}];

5. Use this notification for catching the response of the Payment status

-(void)responseReceived:(NSNotification *) notification{

NSString *strConvertedRespone = [NSString stringWithFormat:@"%@",notification.object];
NSLog(@"Response Received %@",strConvertedRespone);

NSError *serializationError;
id JSON = [NSJSONSerialization JSONObjectWithData:[strConvertedRespone dataUsingEncoding:NSUTF8StringEncoding] options:kNilOptions error:&serializationError];
if (serializationError == nil && notification.object) {
    NSLog(@"%@",JSON);
	
	// Parse the response and show the user with some success or error message and integrate with the app flow

}

}
