I need to make a call to a payment gateway with a button action that integrates their code in my Buzztouch project. What is the best way to go about it? Work on the . h and .m files of a blank plugin? Just for a button action? Or is there a simpler way?

I've had success calling an entire screen from the external url option where a php script I host that shows the payment page and submits to gateway and returns response in the screen. That is the easiest if you're more familiar with php. If you're more comfortable with the native side then most payment gateways take a POST string formatted correctly, below is something that should work for the NMI gateway, or any other if you add the additional parameters that your gateway requires: NSString *username = @"demo"; NSString *password = @"password"; NSString *transactAmount = amount.text; NSString *post = [NSString stringWithFormat:@"?username=%@&password=%@&amount=%@", [self urlEncodeValue:username], [self urlEncodeValue:password], [self urlEncodeValue:transactAmount]; NSString *hostStr = @"https://secure.networkmerchants.com/api/transact.php"; hostStr = [hostStr stringByAppendingString:post]; NSData *dataURL = [NSData dataWithContentsOfURL: [ NSURL URLWithString: hostStr ]]; NSString *serverOutput = [[NSString alloc] initWithData:dataURL encoding: NSASCIIStringEncoding]; NSArray *responseData = [serverOutput componentsSeparatedByString:@"&"]; // full Response String NSString *responseTextFull = [responseData objectAtIndex:1]; NSArray *responseTextParts = [responseTextFull componentsSeparatedByString:@"="]; NSString *responseText = [responseTextParts objectAtIndex:1];

That is very nice of you Merchantguy. Thanks for taking the time to share your code. When programmers work on 'real world' solutions, things get interesting:) I am an Objectiv-C novice and I will have to find out where exactly to put that POST string you mention. My pages in XCode are all in Jquery Mobile and so are the buttons. A Php script could be an easier call, but what about security?

When you use the plugin of "external URL" or whatever it's called make sure you use ssl and you're good.

Thanks a lot, I will look at that. (Sounds appealing after a day trying to get XCode 4.3 to talk nice to Jquery.)
