Known Issues

If you attempt to start using the chargify.erl API from the console starting like this:

erl -pa ebin/ deps/*/ebin

Once you make your first call to the API, you will encounter an error because it cert.pem is not found.

You must start like this if you're testing from the console:

cd ..
erl -pa chargify/ebin/ chargify/deps/*/ebin
