Yes we are. We’ve tried with and without quotes.
We’re encountering the same issue — even tried sending the CURL command via SSH, with the correct URL and Oauth token. Here’s what we get back in the Debug tab of PNFW Settings:
/pnfw/register/ API Error (401) from IP address <#.#.#.#>: Unauthorized, Parameter oauth_consumer_key is missing.
Can you please reply to my support ticket?
