Hi Yu Wang Thanks for your reply. For getting token, I can pass request to Yahoo successful by using PLAINTEXT. But HMAC-SHA1 is fail. However, I want to get contact list by using Yahoo API. In final step of calling Yahoo API, I need to send the request with HMAC-SHA1. It always show 403 error message. I'm suppose that something wrong when I pass request with HMAC-SHA1. I tried to get request token with HMAC-SHA1. I think that getting request token successful with HMAC-SHA1, calling API should be ok. But HMAC-SHA1 still fail whether taking token or calling API.
