Background task execution is not working as expected

I have a requirement to make an web-service call up on tapping actionable buttons from the Remote notification.

On the Remote notification, we have two buttons "Details" and "Fetch". "Fetch" is a background action (Activation Mode = UIUserNotificationActivationModeBackground) and will send some data with out launching the app.

On tapping "Fetch", i made a web-service call to send some details which i got from remote notification.

I have used NSURLSession to send those data to server.

NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration backgroundSessionConfigurationWithIdentifier:@"com.applewatch.sample"];

self.session = [NSURLSession sessionWithConfiguration:sessionConfiguration delegate:self delegateQueue:nil];

NSURLSessionUploadTask *dataTask = [self.session uploadTaskWithRequest:mutableURLRequest fromData:nil];
[dataTask resume];

This works fine when the app is in active state but not in the suspended mode. What i meant to say here is, Once we get the Remote notification and if act after 1 hour on the notification, the service request is not going through.

I suspect, the service request is not going through because the app is in suspended mode/termination mode.

Could some help me how to make service calls in the background.

Note: I have not enabled "Background Fetch" options in info.plist.

Let me know if need to enable and implement the service calls in the UIApplication delegate

I'm not being able to recall or find again where I read this information before, but try using

- uploadTaskWithRequest:fromFile:

I believe it's the only upload method that will work in background
