Does anyone have any experience with Oauth1.0a? Specifically I'm having difficulty with getting the Access Token when using Matlab to access Etrade's API. Everything runs smoothly up to that point, but when I make the call to their Get Access Token API it returns an error stating my Request Token is invalid or expired. Since I'm well within the 5-minute expiration time for the token, it has to be invalid for some reason, but I can't figure out why (since I'm doing exactly the same process as I did for Get Request Token, but with the addition of the Token Secret to the signature key, and the verifier in the Auth header.
In attached script, I'm stuck at line 83, in function "get_access_token1". The funcitons are all wrapped in a class EtradeOauth, that is constructed by EtradeOauth(CONSUMERKEY, CONSUMERSECRET). Most of it is built based on Andy Campbel'sl post about linking to Twitter's API which was really helpful, but unless I'm mistaken (and I easily could be), he never had to request or use an Access Token. Does anyone have any experience with Oauth 1.0a or Etrade's API? Any eagle eyes see what's wrong in my script?

I am curious, did you ever get the Etrade API to work properly in MATLAB? Any advice?

it seems you need to add following to ine 55, and it will work
params.oauth_token=pct_decode(params.oauth_token);
