# Invalid Format for Authorization header

 * Hi! I looked up this topic and there were only 2 threads that were already closed
   to comments, so I’m opening up this one. The other 2 threads didn’t seem to be
   the same issue I’m having though.
 * I get Cloudflare through Bigscoots, which houses the API key. However, when I
   try to paste it into the WP Fastest Cache under the CDN section, it gives me 
   the error “Invalid Format for Authorization header”. I tried both the API key
   and the user key in case I was plugging in the wrong key, but get the same message
   for both.
 * Are you able to help with this?
 * Thanks!
 * Catherine

 * this is not API-KEY. it is API-TOKEN. please make sure you get the api-token 
   as in the post below.

 * Hi Emre,
 * Thanks, yes, I had those instructions. This is now resolved though. For anyone
   that has Cloudflare through Bigscoots, Bigscoots has to apply for the API token.
   They were able to apply for one and integrate.
 * Cheers!
