Unable to get request token using HMAC-SHA1

Sriram Viswanathan1 Jul 2010 2:17 AM

Hi,

I am unable to get request token using HMAC-SHA1

This is the call

https://api.login.yahoo.com/oauth/v2/get_request_token?
oauth_nonce=gettingToken
&oauth_timestamp=1277975227
&oauth_consumer_key=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
&oauth_signature_method=HMAC-SHA1
&oauth_signature=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
&oauth_version=1.0
&oauth_callback=http://yahoo.com/

I am getting oauth_problem=signature_invalid.

I am using the Consumer key and Consumer secret for oauth_consumer_key and oauth_signature respectively.

Thanks in Advance

When I use oauth_type=plaintext, I get the token and all other details.

But the problem is for fetching the guid, if I send oauth_type=plaintext, I get an error which says, oauth_type rejected.

Correction, I was referring to oauth_signature_method, mistakenly wrote it as oauth_type.

Hi Sriram,

Can you please provide the ckey and signature? Actually
there is no secrecy in the ckey because in the OAuth flow,
any user can see it in the request parameters.
