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,
