Key not set or invalid!

How do I properly enter in the API KEY to allow blesta to create accounts?

I have put in the CWP api and the blesta api straight into this file;
/usr/local/cwp/.conf/.api_keys

I also had to create the following file and put in the IP for my blesta install in
/usr/local/cwp/.conf/api_allowed.conf

as I was getting the api error also.
