Access not configured YouTube API

I am attempting to add the ability to view certain videos from YouTube into an iOS app I am creating. I have an API key from Google and have enabled the YouTube API from the Developer Console, as comments are suggesting. This is not the issue. I have a very simple method that collects the details of a specific YouTube channel from it's ID which I will then use to find all of that channels uploaded videos. The issue I'm having is it says my Access is not Configured. Here is everything I have done: The method to grab the information (obviously I haven't included my key or the channel ID there): ``` - (void)collectChannelData { GTLServiceYouTube *service = [[GTLServiceYouTube alloc] init]; service.APIKey = @"API_KEY"; GTLQueryYouTube *query = [GTLQueryYouTube queryForChannelsListWithPart:@"contentDetails"]; query.channelId = @"CHANNEL_ID"; GTLServiceTicket *ticket = [service executeQuery:query completionHandler:^(GTLServiceTicket *ticket, id object, NSError *error) { if (!error) { GTLYouTubeChannelListResponse *channelItem = object; NSLog(@"%@", channelItem); } else { NSLog(@"%@", error); } }]; } ``` I have ensured the the YouTube Data API v3 has been switched on in the Google Developer Console, and the Bundle Identifier matches what is in my Info.plist The error message I receive is: Error Domain=com.google.GTLJSONRPCErrorDomain Code=403 "The operation couldn’t be completed. (Access Not Configured. Please use Google Developers Console to activate the API for your project.)" UserInfo=0xa3aa0e0 {error=Access Not Configured. Please use Google Developers Console to activate the API for your project., GTLStructuredError=GTLErrorObject 0x8a74630: {message:"Access Not Configured. Please use Google Developers Console to activate the API for your project." code:403 data:[1]}, NSLocalizedFailureReason=(Access Not Configured. Please use Google Developers Console to activate the API for your project.)} I cannot find any reason why this would not work. I believe I am correct in that I should not need to set up a billing account or need oAuth for this specific request. I can also see in the overview for my app on the Developer Console that multiple requests have been received but there is an error for each request. I just can't figure out why it's rejecting it. Thanks for any help.
