I am trying to get a request token, but keep getting the following error:
401 Response: oauth_problem=consumer_key_unknown
I am using GET on this URL
My callback domain is verified.
In an effort to get a different error, I have passed an empty value for oauth_consumer_key.
In that case, I get this error:
What could be wrong with my oauth_consumer_key when I am actually passing it?
Finally got back to this. Turns out I did not make a "Project." I made something that ended up in the Projects section, but was actually "Additional API Information." Still makes the two keys, so it looks just like what you are trying to do.
It's been a while. But I think I initially followed some tutorial workflow for setting up the login. That appeared to be setting up a Project, but really did not.
To make a project, click the "My Project" link in the upper right corner of this page, mouse over your name/icon.
The My Projects page has a big "Create a Project" button.
It was still a bit doggy, even then :)
