Hi ,
I am working on spring social flickr project. Flickr uses OAuth1 authentication. During authorize i need to send permission parameter ( 'perms' ) having values like ( 'read' , 'write' and 'delete'). I have checked that we can send additional parameter ('scope') through OAuth2 using getOAuth2Parameters() function in ConnectSupport.java. But there seems no provision to send additional parameter in OAuth1 as ConnectSupport.java sending 'null' as in buildOAuthUrl(connectionFactory, request, null). Is there any way I can send 'perms' parameter through ProviderSignInController?
