Yahoo OAuth with gtm-oauth for Mac App

[Scott Falbo]

I'm having trouble using this library with Yahoo's OAuth to create a
Mac desktop app. I've modified the Twitter variables in the
OAuthSample project to point to Yahoo instead but I consistently
receive 401 errors. Here is how I've modified the code:

Within signInToTwitter:
NSURL *requestURL = [NSURL URLWithString:@"https://api.login.yahoo.com/
oauth/v2/get_request_token"];
NSURL *accessURL = [NSURL URLWithString:@"https://api.login.yahoo.com/
oauth/v2/get_token"];
NSURL *authorizeURL = [NSURL URLWithString:@"https://
api.login.yahoo.com/oauth/v2/request_auth"];
NSString *scope = @"https://api.login.yahoo.com";

I also updated authForTwitter to include my Yahoo key & secret.

Any advice is greatly appreciated.

Yahoo's OAuth implementation appears to be a bit non-standard.

I was able to get it to work with GTMOAuth with a few small changes.

Set the scope and the display name to nil, like

windowController = [[[GTMOAuthWindowController alloc] initWithScope:nil

language:nil

requestTokenURL:requestURL

authorizeTokenURL:authorizeURL

accessTokenURL:accessURL

authentication:auth

appServiceName:kYahooKeychainItemName

resourceBundle:nil] autorelease];

[auth setDisplayName:nil];

Also, be sure that the callback matches the URL registered with Yahoo:

[auth setCallback:@"http://www.example.net/OAuthCallback"];  // use your registered callback URI

OAuth 1 debugging is unfortunately a bit of a black art. I have added a "Debugging Tips" section to the Introduction wiki page for the project.

Thank you very much Greg - this worked for me as well.

Where do you set the callback URL in project settings (not within App
code)? I only see "developer website" in the Yahoo developer panel for
my project.
