FIRST ERROR
I use this code but I don't know how to use the api Mailjet in iOS ? Where to put the API key private, the public etc... I check the github mailjet, the doc mailJet about the API without success.
NSData *data = [NSData dataWithContentsOfFile:filePath];
NSLog(@"File Size: %lu",(unsigned long)[data length]);
//set up request
NSMutableURLRequest *request= [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:@"https://api.mailjet.com/v3/send"]];
[request setHTTPMethod:@"POST"];
//required xtra info
NSString *boundary = @"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];
//body of the post
NSMutableData *postbody = [NSMutableData data];
[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"thefile\"; filename=\"recording\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[@"Content-Type: application/octet-stream\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:data];
[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postbody];
NSURLConnection *apiConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
I do tests with sending "manually", and I have that bad answer. Where I have to put the API KEY and the SECRET KEY ?
