C#: autenticazione

Esempio di chiamata alla funzione di autenticazione

La chiamata  usa la funzione user_authentication passando

• la userid e la password di accesso alle API:  interface_code e interface_password
• la userid e la password di un utente Documatica: user@acme.it e user_pass

Il codice elabora anche la risposta, producendo OK in caso di successo e il codice di errore in caso di fallimento.

Il codice utilizza la libreria NewtonSoft  per trattare le strutture JSON.
