Sinao API

Use a Sinao user account, then call the login endpoint documented in Authentification / Login with the account email and password to obtain a bearer token. The docs say the token is valid for 24h and can be refreshed for 14 days via `/refresh`.

In the Sinao web interface, create an API key as the company application's administrator. The Authentification guide says this key is created from the Sinao interface by the company's admin user, is tied to a single application, and does not expire. Then send it as header Api-Key.
