PayPal error 580001 HTTP Request from iOS - ios

Question

Having some difficulties in implementing Adaptive payments in iOS and unfortunately there is very little documentation on PayPal's website or response. This is the code:
- (void)makePaymentSandbox{
NSError *error;
//NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
//NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
NSURL *url = [NSURL URLWithString:#"https://svcs.sandbox.paypal.com/AdaptivePayments/Pay"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:30.0];
//setting
[request setHTTPMethod:#"POST"];
//headers
[request addValue:#"alex-facilitator_api1.fastwebnet.it" forHTTPHeaderField:#"X-PAYPAL-SECURITY-USERID"];
[request addValue:#"FW79EZXASW69NE8X" forHTTPHeaderField:#"X-PAYPAL-SECURITY-PASSWORD"];
[request addValue:#"ABZua9nnv9oieyN4MwVt15YdgetaJHcyzqOHjkLbuM-bGRoI7WRS" forHTTPHeaderField:#"X-PAYPAL-SECURITY-SIGNATURE"];
//NV
[request addValue:#"JSON" forHTTPHeaderField:#"X-PAYPAL-REQUEST-DATA-FORMAT"];
[request addValue:#"JSON" forHTTPHeaderField:#"X-PAYPAL-RESPONSE-DATA-FORMAT"];
[request addValue:#"APP-80W288712P519543T" forHTTPHeaderField:#"X-PAYPAL-APPLICATION-ID"];
[request addValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request addValue:#"en_US" forHTTPHeaderField:#"Accept-Language"];
//data
/*NSString *userUpdate =[NSString stringWithFormat:#"clientDetails.applicationId=%#&actionType=%#",#"APP-80W284485P519543T", #"PAY",nil];
NSData *data1 = [userUpdate dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPBody:data1];
[request setValue: [NSString stringWithFormat:#"%lu", (unsigned long)[data1 length]] forHTTPHeaderField:#"Content-Length"];*/
NSDictionary *mapData = [[NSDictionary alloc] initWithObjectsAndKeys:
#"PAY", #"actionType",
#"USD", #"currencyCode",
#"http:\\www.cleverlyapp.com", #"cancelUrl",
#"http:\\www.cleverlyapp.com", #"returnUrl",
#"ReturnAll", #"requestEnvelope.detailLevel",
#"en_US", #"requestEnvelope.errorLanguage",
#"seneder#email.com", #"senderEmail",
#"0.1", #"receiverList.receiver(0).amount",
#"a-buyer#fastwebnet.it", #"receiverList.receiver(0).email",
#"0.1", #"receiverList.receiver(1).amount",
#"a-facilitator#fastwebnet.it", #"receiverList.receiver(1).email",
#"APP-80W284485P519543T", #"clientDetails.applicationId",
nil];
NSData *postData = [NSJSONSerialization dataWithJSONObject:mapData options:0 error:&error];
[request setHTTPBody:postData];
[NSURLConnection connectionWithRequest:request delegate:self];
}
Here's the response:
String: {
error = (
{
category = Application;
domain = PLATFORM;
errorId = 580001;
message = "Invalid request: {0}";
severity = Error;
subdomain = Application;
}
);
responseEnvelope = {
ack = Failure;
build = 17325060;
correlationId = e82ede718b929;
timestamp = "2015-07-14T09:50:06.222-07:00";
};
}

Answer 1

check these please:
Adaptive Payments Pay API Error 580001
580001 Invalid request: {0} PayPal (PHP)
Error 580001
some have to do with encoding, set as JSON, but actualy sent as URL-encoded, etc, others have to do with currency and currency format used (e.g values sent should not include currency sign etc..)

Finally got it to work. The headers are correct, the input data had some problems. This is the correct version of the code:
- (void)makePaymentSandboxWithPreapprovalToEmail:(NSString *)toEmail withCurrency:(NSString *)currency andAmount:(NSString *)moneyAmount completition:(void (^)(BOOL, NSString *))block{
NSError *error;
NSURL *url = [NSURL URLWithString:#"https://svcs.sandbox.paypal.com/AdaptivePayments/Pay"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:30.0];
//setting
[request setHTTPMethod:#"POST"];
//headers
[request addValue:#"alex.rietmann-facilitator_api1.fastwebnet.it" forHTTPHeaderField:#"X-PAYPAL-SECURITY-USERID"];
[request addValue:#"FW7ADTYZFP68XE0X" forHTTPHeaderField:#"X-PAYPAL-SECURITY-PASSWORD"];
[request addValue:#"ABSua9nnv9nnkoN4MwVt15YdgetaJHcyzqOHjkLbuM-bGRoI7JRS" forHTTPHeaderField:#"X-PAYPAL-SECURITY-SIGNATURE"];
//NV
[request addValue:#"JSON" forHTTPHeaderField:#"X-PAYPAL-REQUEST-DATA-FORMAT"];
[request addValue:#"JSON" forHTTPHeaderField:#"X-PAYPAL-RESPONSE-DATA-FORMAT"];
[request addValue:#"APP-80W284485P519543T" forHTTPHeaderField:#"X-PAYPAL-APPLICATION-ID"];
[request addValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request addValue:#"en_US" forHTTPHeaderField:#"Accept-Language"];
//other email
NSDictionary *receiver0 = [[NSDictionary alloc] initWithObjectsAndKeys: toEmail, #"email", moneyAmount, #"amount", #"true", #"primary", nil];
//my account
NSDictionary *receiver1 = [[NSDictionary alloc] initWithObjectsAndKeys: #"alex.rietmann-facilitator#fastwebnet.it", #"email", #"2", #"amount", nil];
NSDictionary *options0 = [[NSDictionary alloc] initWithObjectsAndKeys: [NSArray arrayWithObjects:receiver0, receiver1, nil], #"receiver", nil];
NSDictionary *mapData = [[NSDictionary alloc] initWithObjectsAndKeys:
#"PAY", #"actionType",
#"EACHRECEIVER", #"feesPayer",
#"true", #"reverseAllParallelPaymentsOnError",
currency, #"currencyCode",
[PaymentManager readPaymentCode], #"preapprovalKey",
[PaymentManager readPaymentEmail], #"senderEmail",
#"http:\\www.apple.com", #"cancelUrl",
#"http:\\www.google.com", #"returnUrl",
[[NSDictionary alloc] initWithObjectsAndKeys:#"en_US", #"errorLanguage", #"detailLevel", #"ReturnAll", nil], #"requestEnvelope",
//[[NSDictionary alloc] initWithObjectsAndKeys: options0, #"0", nil], #"receiverList",
options0, #"receiverList",
[[NSDictionary alloc] initWithObjectsAndKeys:#"APP-80W284485P519543T", #"applicationId", [self getIPAddress], #"ipAddress", nil], #"clientDetails",
//#"APP-80W284485P519543T", #"clientDetails.applicationId",
//[self getIPAddress], #"clientDetails.ipAddress",
nil];
NSData *postData = [NSJSONSerialization dataWithJSONObject:mapData options:0 error:&error];
[request setHTTPBody:postData];
MyConnection * connection = [[MyConnection alloc]initWithRequest:request];
[connection setCompletitionBlock:^(id obj, NSError *err) {
if (!err) {
NSError *error = nil;
NSDictionary* revDicn =[NSDictionary dictionary];
revDicn = [NSJSONSerialization JSONObjectWithData:obj options:NSJSONReadingMutableContainers error:&error];
NSLog(#"Response: %#", revDicn);
if ([[revDicn objectForKey:#"paymentExecStatus"] isEqualToString:#"COMPLETED"]) {
block(YES, [revDicn objectForKey:#"payKey"]);
}else{
block(NO, #"");
}
} else {
//There was an error
block(NO, #"");
}
}];
[connection start];
}
This line is optional:
[PaymentManager readPaymentCode], #"preapprovalKey",
The use of it depends on whether you wish to use pre-approval or not. This explains in detail the use of pre-approval: https://developer.paypal.com/webapps/developer/docs/classic/adaptive-payments/ht_ap-basicPreapproval-curl-etc/. Replace the input values in the code above and you will get the pre-approval key.

Working code. Please check.
int amount = 195;
// int x = 146;
NSDictionary *parameters;
parameters = #{

#"requestEnvelope" : #{#"errorLanguage":#"en_US", #"detailLevel":#"ReturnAll"}
};
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:parameters
