PayFort Payment Integration In IOS.

PayFort

In most of the time, we have to integrate the application with the payment gateway like a payfort payment gateway. for this, we have to follow some steps to integrate a correct integration payment SDK in IOS.

1: go to that URL and download SDK.

https://docs.payfort.com/

2: for success full launch the payfort gateway we need some sample predefined data.

3: we need a signature value that is required at the time to load payfort window. to generate a signature

NSMutableString *post = [NSMutableString string];
    [post appendFormat:@"tnraetanaeaccess_code=%@", @"3Akqd81fWPfnE5L"];
    [post appendFormat:@"device_id=%@",  [PayFort getUDID ]];
    [post appendFormat:@"language=%@", @"en"];
    [post appendFormat:@"merchant_identifier=%@", @"azPOCM"];
    [post appendFormat:@"service_command=%@", @"SDK_TOKENtnraetanae"];

NSMutableString *post = [NSMutableString string];

[post appendFormat:@"tnraetanaeaccess_code=%@", @"3Akqd81fWPfnE5L"];

[post appendFormat:@"device_id=%@", [PayFort getUDID ]];

[post appendFormat:@"language=%@", @"en"];

[post appendFormat:@"merchant_identifier=%@", @"azPOCM"];

[post appendFormat:@"service_command=%@", @"SDK_TOKENtnraetanae"];

[self sha1Encode:post]

- (NSString*)sha1Encode:(NSString*)input {
    const char *cstr = [input cStringUsingEncoding:NSUTF8StringEncoding];
    NSData *data = [NSData dataWithBytes:cstr length:input.length];
    
    uint8_t digest[CC_SHA256_DIGEST_LENGTH];
    
    CC_SHA256(data.bytes, (int)data.length, digest);
    
    NSMutableString* output = [NSMutableString stringWithCapacity:CC_SHA256_DIGEST_LENGTH * 2];
    
    for(int i = 0; i < CC_SHA256_DIGEST_LENGTH; i++)
        [output appendFormat:@"%02x", digest[i]];
    
    return output;
}

- (NSString*)sha1Encode:(NSString*)input {

const char *cstr = [input cStringUsingEncoding:NSUTF8StringEncoding];

NSData *data = [NSData dataWithBytes:cstr length:input.length];

uint8_t digest[CC_SHA256_DIGEST_LENGTH];

CC_SHA256(data.bytes, (int)data.length, digest);

NSMutableString* output = [NSMutableString stringWithCapacity:CC_SHA256_DIGEST_LENGTH * 2];

for(int i = 0; i < CC_SHA256_DIGEST_LENGTH; i++)

[output appendFormat:@"%02x", digest[i]];

return output;

}

4: you will get signature value now you have to make a http request to get SDK token for launching payfort controller.

 NSDictionary *tmp = [[NSDictionary alloc] initWithObjectsAndKeys:
                         @"SDK_TOKEN", @"service_command",
                          @"azPOCM", @"merchant_identifier",
                         @"3Akqd81fWPfnE5L", @"access_code",
                         [self sha1Encode:post],@"signature",
                         @"en", @"language",
                         [PayFort getUDID ], @"device_id",
                         nil];
    
    NSError *error;
    NSData *postdata = [NSJSONSerialization dataWithJSONObject:tmp options:0 error:&error];
    
    
        NSString *BaseDomain =@"https://sbpaymentservices.payfort.com/FortAPI/paymentApi";
        NSString *urlString = [NSString stringWithFormat:@"%@",BaseDomain];
        //NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
        NSString *postLength = [NSString stringWithFormat:@"%ld",[postdata length]];
        NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
        [request setURL:[NSURL URLWithString:urlString]];
        [request setHTTPMethod:@"POST"];
        [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
        [request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
        [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
        //[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
        [request setHTTPBody:postdata];
        
        //NSLog(@"signal mname %@", signalNameFunction);
        NSLog(@"url string %@",urlString);
        NSLog(@"url post %@",tmp);
        
        // NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request  delegate:self];
        NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];
        if(connection){
            webDataglobal = [NSMutableData data];
        }
        else{
            NSLog(@"The Connection is null");
        }
    
    
    
}
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{
    [webDataglobal setLength: 0];
}

-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{
    [webDataglobal appendData:data];
}

-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error{
    NSLog(@"error %@",error);
}

-(void)connectionDidFinishLoading:(NSURLConnection *)connection{
    
    id collection = [NSJSONSerialization JSONObjectWithData:webDataglobal options:0 error:nil];
    NSLog(@"receive data %@",collection);
    sdk_token = collection[@"sdk_token"];
    [self launch];
    

}

NSDictionary *tmp = [[NSDictionary alloc] initWithObjectsAndKeys:

@"SDK_TOKEN", @"service_command",

@"azPOCM", @"merchant_identifier",

@"3Akqd81fWPfnE5L", @"access_code",

[self sha1Encode:post],@"signature",

@"en", @"language",

[PayFort getUDID ], @"device_id",

nil];

NSError *error;

NSData *postdata = [NSJSONSerialization dataWithJSONObject:tmp options:0 error:&error];

NSString *BaseDomain =@"https://sbpaymentservices.payfort.com/FortAPI/paymentApi";

NSString *urlString = [NSString stringWithFormat:@"%@",BaseDomain];

//NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

NSString *postLength = [NSString stringWithFormat:@"%ld",[postdata length]];

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];

[request setURL:[NSURL URLWithString:urlString]];

[request setHTTPMethod:@"POST"];

[request setValue:postLength forHTTPHeaderField:@"Content-Length"];

[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];

[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

//[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];

[request setHTTPBody:postdata];

//NSLog(@"signal mname %@", signalNameFunction);

NSLog(@"url string %@",urlString);

NSLog(@"url post %@",tmp);

// NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];

if(connection){

webDataglobal = [NSMutableData data];

}

else{

NSLog(@"The Connection is null");

}

-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{

[webDataglobal setLength: 0];

}

-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{

[webDataglobal appendData:data];

}

-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error{

NSLog(@"error %@",error);

}

-(void)connectionDidFinishLoading:(NSURLConnection *)connection{

id collection = [NSJSONSerialization JSONObjectWithData:webDataglobal options:0 error:nil];

NSLog(@"receive data %@",collection);

sdk_token = collection[@"sdk_token"];

[self launch];

}

above code will produce SDK token now you have to take view controller and their class name write “PayFortController” .

- (void)viewDidLoad {
    [super viewDidLoad];
    PayFort = [[PayFortController alloc]initWithEnviroment:KPayFortEnviromentSandBox];
}

- (void)viewDidLoad {

[super viewDidLoad];

PayFort = [[PayFortController alloc]initWithEnviroment:KPayFortEnviromentSandBox];

}

-(void) launch{
    PayFort.delegate = self;
    NSMutableDictionary *request = [[NSMutableDictionary alloc]init];
    [request setValue:@"10000" forKey:@"amount"];
    [request setValue:@"PURCHASE" forKey:@"command"];
    [request setValue:@"SAR" forKey:@"currency"];
    [request setValue:@ "customer@domain.com" forKey:@"customer_email"];
    [request setValue:@"en" forKey:@"language"];
    [request setValue:@"XYZ9239-yu892Q78" forKey:@"merchant_reference"];
    [request setValue:sdk_token forKey:@"sdk_token"];
    [PayFort setPayFortRequest:request]; // Must Send [payFort callPayFort:self]
    
    PayFort.IsShowResponsePage = YES;
    [PayFort callPayFort:self];

    
}

-(void) launch{

PayFort.delegate = self;

NSMutableDictionary *request = [[NSMutableDictionary alloc]init];

[request setValue:@"10000" forKey:@"amount"];

[request setValue:@"PURCHASE" forKey:@"command"];

[request setValue:@"SAR" forKey:@"currency"];

[request setValue:@ "[email protected]" forKey:@"customer_email"];

[request setValue:@"en" forKey:@"language"];

[request setValue:@"XYZ9239-yu892Q78" forKey:@"merchant_reference"];

[request setValue:sdk_token forKey:@"sdk_token"];

[PayFort setPayFortRequest:request]; // Must Send [payFort callPayFort:self]

PayFort.IsShowResponsePage = YES;

[PayFort callPayFort:self];

}

Now it will launch and you can take dummy card number from their site.

5: you can get a response from that method.

– (void)sdkResult:(id)response{

NSLog(@”data— %@”,response);

}

hi, i am getting signature mismatch. How to resolve this issue ?.

kunal prasad (Moderator) 8 years ago
check your shaencode parameter and http request for getting sdk_token. both parameter contain the correct value.
example — NSMutableString *post = [NSMutableString string];
[post appendFormat:@”tnraetanaeaccess_code=%@”, @”3Akqd81fWPfnE5LHz”];
[post appendFormat:@”device_id=%@”, [PayFort getUDID ]];
[post appendFormat:@”language=%@”, @”en”];
[post appendFormat:@”merchant_identifier=%@”, @”azPOC”];
[post appendFormat:@”service_command=%@”, @”SDK_TOKENtnraetanae”];

NSDictionary *tmp = [[NSDictionary alloc] initWithObjectsAndKeys:
@”SDK_TOKEN”, @”service_command”,
@”azPOC”, @”merchant_identifier”,
@”3Akqd81fWPfnE5LHz”, @”access_code”,
[self sha1Encode:post],@”signature”,
@”en”, @”language”,
[PayFort getUDID ], @”device_id”,
nil];

hi, i am getting signature mismatch. I checked both values in shaencode parameter and request parameters all are same.

if your current viewcontroller where you are loading payfort then it will be associated with uinavigationcontroller
UINavigationController -> currentview

How to get merchant Identifier (PSPID) ?

Kunal Prasad 7 years ago
for that you need to ask from payfort team ( That will provide you ).

Hello sir,

We are integrating pay fort SDK for iOS from document provided by you https://docs.payfort.com/docs/mobile-sdk/build/index.html#sdk-token-urls

We are getting stuck at very first step where we need to get SDK token for payment

We are getting Signature mismatch error every time I call https://sbpaymentservices.payfort.com/FortAPI/paymentApi API

Let me give you parameters that I am passing in API :

API : https://sbpaymentservices.payfort.com/FortAPI/paymentApi API

Parameter :
“access_code” = XNEw23o2DodbqTOLR6V3;
“device_id” = “360B7CA4-ABF7-4A00-8EE8-99E3411F6994”;
language = en;
“merchant_identifier” = qxbVGjJK;
“service_command” = “SDK_TOKEN”;
signature = 0cdb4c9b705826de3fd3b548515f5916197ff3f38965a38e5527ce9654387623;

I am getting Signature mismatch error when I call above API

And for signature generation I have used same steps provided by you in documents

Can you please help me to get rid out of this or can assist us for better solution ?

Thanks

Hi,
you need token from server side its just confirms that wether you are valid customer or not.
time to time payfort change their rule and regulation so better to follow update document.
you will get also dummy credential from their documentation.

for successful signature

you need to pass correct value (this one is demo value)
[request setValue:@”XYZ9239-yu892Q78″ forKey:@”merchant_reference”];
[request setValue:sdk_token forKey:@”sdk_token”];

and . this one (this is demo data)

NSDictionary *tmp = [[NSDictionary alloc] initWithObjectsAndKeys:
@”SDK_TOKEN”, @”service_command”,
@”azPOCM”, @”merchant_identifier”,
@”3Akqd81fWPfnE5L”, @”access_code”,
[self sha1Encode:post],@”signature”,
@”en”, @”language”,
[PayFort getUDID ], @”device_id”,
nil];

if this one is correct than it will become success.fd
