You need to use the API KEY GENERATED. Important! DO NOT USE the API KEY ID. Sendgrid only displays the generated key once when you create it. If you didn't record it somewhere when you created the key you'll need to create a new key and then you'll probably want to delete the old key since it would be useless if you don't know what it is.
