MAking API request always got "token_rejected" error

I have developed a OAuth Component, and completed Yahoo's OAuth Process, got oauth_token.

But when I make API call to yahoo API (like contact or YQL), I always get "Token_Rejected" error message.

HTTP 401

Response:

<?xml version='1.0' encoding='UTF-8'?>
<yahoo:error xmlns:yahoo='http://yahooapis.com/v1/base.rng'
xml:lang='en-US'>
<yahoo:description>Please provide valid credentials. OAuth oauth_problem="toke
n_rejected", realm="yahooapis.com"</yahoo:description>
</yahoo:error>

I am very sure this access token is not expired.

How to resolve this problem? Thanks.

I had resolved this question, the reason is I missed query string, when I encoded query string into base string, this issue had been solved.

For anyone coming across this question in the future: If you keep getting "token rejected" from https://api.login.yahoo.com/oauth/v2/get_token using PHP. Then make sure, if relevant to your flow, that you are calling urldecode on the access token prior to making this call.

If you're storing the access token in a table, and then calling the API using the access token from that table, it will get shortened to 255 characters if you made the column a string. I just changed it from a string to a text and stored it.

This is of course if you are storing the access token in a table and then making the call. I had this exact same error message, once I fixed that it worked.

Hope I could help,

Goran
