Calling server API and sending response to WatchKit

I want to make an API request from my watch app using openParenApplication and handleWatchKitExtensionRequest.

The API call from handleWatchKitExtensionRequest would get data from the server and send that data to WatchKit app as a reply.

How can I accomplish this?

Make sure you use a background task in your handleWatchKitExtensionRequest method (check here for some advice: http://www.fiveminutewatchkit.com/blog/2015/3/11/one-weird-trick-to-fix-openparentapplicationreply), then simply call reply() in the your API call's completion block (or similar) and pass the results.

In your Watch:

[WKInterfaceController openParentApplication:@{@«request» : «myRequest» } reply:^(NSDictionary *replyInfo, NSError *error) {
            if (!error) {
                // Parse your result here                
            }
            else {
                // Manage Error
            }
        }];

In app delegate

- (void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void (^)(NSDictionary *replyInfo))reply
{
    if ([userInfo["request"] isEqualToString:"myRequest"]) {
dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0ul);
        dispatch_async(queue, ^(void) {

            NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:userInfo[@«request »]]];
            dispatch_async(dispatch_get_main_queue(), ^{
                if (imageData) {
                    reply(@{«result» : imageData});
                }
                else {
                    reply(@{«error» : @"error"});
                }
            });
        });
    }else {reply(@{}); }}
