OAuth oauth_problem="signature_invalid" in Java

Yahoo Developers, if you guys have anything to do with Contact API please help me fix this issue...I have tried everything possible.

Here is my base String: GET&http%3A%2F%2Fsocial.yahooapis.com%2Fv1%2Fuser%2FXLMJQDSNDXMSNBOEHW25ARJEWU%2Fcontacts&
oauth_consumer_key%3Ddj0yJmk9WUsyWFdJcnZFQW1uJmQ9WVdrOVRIcDFURFpnbWNHbzlOakUyT1RVME5EazMmcz1jb25zdW

Key is encode(Shared Secret) + "&"+ encode(Token Secret);
and here is my sign: HbfOb0Tzst3WJHsJUvKaciDlGFQ%3D


What is it that I am doing wrong that I keep going "signature_invalid" response?

Thanks,
Sharan

  • A few things to check.

    • The parameters must be sorted in natural (strcmp) order. So oauth_token should come before oauth_version in your base string.
    • Are you passing the authorization via get parameters or authorization headers? If get, then post the entire url here. If via headers, then post the Authorization: header here. Check to make sure that things are encoded properly.
    • Are you passing any query parameters to the contacts end point that you didn't include in the base string?
    • Are you using the correct token secret that accompanies that oauth token?
