E-Trade released their API recently and provided technical documentation which is somewhat useful but not complete.
Does anyone have a fully working example in C# that shows how this works?
I have been able to do the authentication using OAuth correctly, but when it comes to getting information out of my account or market data, the servers fail.
To use the example class + GitHub's code from jejernig's answer, I used the following:
TokenBase token = new TokenBase { ConsumerKey = "oauth_consumer_key from ETRADE" }; // OAuthRepository only seems to use the consumer key
OAuthRepository rep = new OAuthRepository(token, "consumer_secret from ETRADE");
OAuthSession session = rep.CreateSession();
IToken accessToken = rep.GetAccessToken(session);
I just removed the abstract from BaseOAuthRepository, and had to fix the GitHub code because IOAuthSession.GetUserAuthorizationUrlForToken()'s parameters were reversed (I changed the rest of the code to match the interface's parameters).
I am getting the dreaded Due to a logon delay or other issue, your authentication could not be completed at this time. Please try again. message, but this may be due to an actual logon issue that I have to resolve.
