OAuth oauth_problem=signature_invalid

I have a Consumer Key and Consumer Secret key and use the url https://api.login.yahoo.com/oauth/v2/get_request_token? with other additional parameters to get the request token .
when i tried to use url in IE i encountered error like "IE cannot download get request rom api.login.yahoo.com" .
Next i tried in curl , with the API again error like "WWW-Authenticate: OAuth oauth_problem=signature_invalid".

Can anyone tell me what is the mistake i have done?

Thanks
Melvin

Hi

Thanks for you reply.

Let me give a overall view about my project

I like import user yahoo contacts using Yahoo Contact API. I understand that to get the yahoo contact the following request URL (API ) http://social.yahooapis.com/v1/user/{guid}/contacts has to use .But it needs guid .

I tired to get the guid by following steps
1.Get an API Key
2.Sign Up and Get a Consumer Key
3.Get a Request Token

upto step 3 i got revelant response. but to proceed further step 4 (https://api.login.yahoo.com/oauth/v2/request_auth

). I am not able to get response for the step 4 (Get User Authorization (request_auth) )

step 1 output:

Consumer Key:
Consumer Secret:

step 2 request and response

curl -v -k https://api.login.yahoo.com/oauth/v2/get_request_token? -d oauth_nonce=ce2130523f788f313f76314ed3965ea6 -d oauth_timestamp=1202956957 -d oauth_consumer_key=dj0yJmk9UXdMajF3ektjaWJnJmQ9WVdrOVJuVlhPWHA2TXpZbWNHbzlNakkwT

step 3 request
curl -k -v https://api.login.yahoo.com/oauth/v2/reques...h_token=gsnjqvf -o n2.txt

response


I am getting message in the putput response file , instead of oauth token and oauth verifier.

Kindly help me to fix this issue .

FYI : in the oauth callback pacrameter , i tried with oauth_callback=oob .For this case also , i am getting the above step3

Thanks

Hi Melvin,

The step 3 is not a server-to-server backend call: You should redirect
user's browser to it.

https://api.login.yahoo.com/oauth/v2/reques...h_token=gsnjqvf

so the oauth_token can be authorized. Only after that can you do
a https://api.login.yahoo.com/oauth/v2/get_token call to get user's
access token.

You can check the following document for the step-by-step guide:
http://developer.yahoo.com/oauth/guide/ope...auth-guide.html

Hi

Thanks for your reply.

Here are my other questions:

1. My applciation is not browser based it is device based application. Any way whether it is browser or non browser based we need the token.
2.So i used oauth_Callback = oob , in that case how can i get the oauth_verifier
3. As you said i used the following for redirecting the url by

curl -k -v -L https://api.login.yahoo.com/oauth/v2/reques...h_token=gsnjqvf -o n2.txt [here in curl -L means it will redirect to the url]

Th output is below and there is no oauth_verifier

I also understand to Present the Yahoo! Authorization Page
1.Present the Yahoo! authorization page through a browser pop-up window. (Preferred Method)
2.Redirect from your Web application off-site to the Yahoo! authorization page

In that case if my application is not browser based , how can i do the rdirect.
Is there any special API for that.

Thanks
Melvin

If you are still having problems, I would suggest that you check out:

http://nullinfo.wordpress.com/oauth-yahoo/

As it has code for calling contacts and the API does work. It is also ran from the command-line too.
