iOS PayUMoney SDK-key is not valid - ios

Question

I have integrate payumoney payment gateway. And I am able to create correct hash with the key, but at the end am getting an alert message as "key is not valid".what would be the problem?
Here is the code. I use the link "https://www.payumoney.com/payment-gateway-integration-guide.html" to download the payumoney SDK.
- (IBAction)startPaymentTapped:(id)sender {
[self setPaymentParameters];
//Start the payment flow
PUMMainVController *paymentVC = [[PUMMainVController alloc] init];
UINavigationController *paymentNavController = [[UINavigationController alloc] initWithRootViewController:paymentVC];
[self presentViewController:paymentNavController
animated:YES
completion:nil];
}
- (void)setPaymentParameters {
self.params = [PUMRequestParams sharedParams];
self.params.environment = PUMEnvironmentProduction;
self.params.amount = self.amount.text;
self.params.key = #"mykeyvalue";
self.params.merchantid = #"merchantid";
self.params.txnid = [self getRandomString:2];
self.params.surl = #"https://www.payumoney.com/mobileapp/payumoney/success.php";
self.params.furl = #"https://www.payumoney.com/mobileapp/payumoney/failure.php";
self.params.delegate = self;
self.params.firstname = self.firstname.text;
self.params.productinfo = self.productinfo.text;
self.params.email = self.email.text;
self.params.phone = #"";
self.params.udf1 = #"";
self.params.udf2 = #"";
self.params.udf3 = #"";
self.params.udf4 = #"";
self.params.udf5 = #"";
self.params.udf6 = #"";
self.params.udf7 = #"";
self.params.udf8 = #"";
self.params.udf9 = #"";
self.params.udf10 = #"";
self.params.hashValue = [self getHash];
}
- (NSString *)getRandomString:(NSInteger)length {
NSMutableString *returnString = [NSMutableString stringWithCapacity:length];
NSString *numbers = #"0123456789";
// First number cannot be 0
[returnString appendFormat:#"%C", [numbers characterAtIndex:(arc4random() % ([numbers length]-1))+1]];
for (int i = 1; i < length; i++) {
[returnString appendFormat:#"%C", [numbers characterAtIndex:arc4random() % [numbers length]]];
}
return returnString;
}
- (NSString*)getHash {
NSString *hashSequence = [NSString stringWithFormat:#"mykeyvalue|%#|%#|%#|%#|%#|||||||||||salt",self.params.txnid, self.params.amount, self.params.productinfo,self.params.firstname, self.params.email];
NSString *rawHash = [[self createSHA512:hashSequence] description];
NSString *hash = [[[rawHash stringByReplacingOccurrencesOfString:#"<" withString:#""]stringByReplacingOccurrencesOfString:#">" withString:#""]stringByReplacingOccurrencesOfString:#" " withString:#""];
return hash;
}
- (NSData *) createSHA512:(NSString *)source {
const char *s = [source cStringUsingEncoding:NSASCIIStringEncoding];
NSData *keyData = [NSData dataWithBytes:s length:strlen(s)];
uint8_t digest[CC_SHA512_DIGEST_LENGTH] = {0};
CC_SHA512(keyData.bytes, (CC_LONG)keyData.length, digest);
NSData *output = [NSData dataWithBytes:digest length:CC_SHA512_DIGEST_LENGTH];
NSLog(#"out --------- %#",output);
return output;
}

Answer 1

Please check data when you send payumoney for create hash key with server api data for create your hash key.

Answer 2

self.params.environment = PUMEnvironmentProduction;
Through the above code you can pay using net banking successfully. If you want to test
your payment gateway for dummy credit/debit card some changes are required. I am
listing it down. Try it.
Instead of
self.params.environment = PUMEnvironmentProduction; //write
self.params.environment = PUMEnvironmentTest;
change the urls as
self.params.surl = #"https://test.payumoney.com/mobileapp/payumoney/success.php";
self.params.furl = #"https://test.payumoney.com/mobileapp/payumoney/failure.php";
// We need test url for testing purpose.
Make sure you have activated your payumoney account by clicking on link that you got in mail.
Use the below dummy master card details
Test Card Name: any name
Test Card Number: 5123456789012346
Test CVV: 123
Test Expiry: May 2017
