This gem supplies a `fa` executable which can create, read, update and delete data using the Freeagent API. You need to specify valid Freeagent app credentials. Generate a Freeagent app at https://dev.freeagent.com/apps. Ensure you set 'http://localhost:*/' as a valid OAuth redirect URI. Then export your ID and secret as environment variables FREEAGENT_APP_ID and FREEAGENT_APP_SECRET. On first run, `fa` will authenticate you via OAuth so watch out for an authentication URI printed to the console.
