It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your ExpenseIn credentials.

On first connect you provide an ExpenseIn API key (Admin → Integration → ExpenseIn API → New API Key). The server validates it and stores it per user. No keys go in config files.
