Un account di servizio è un tipo di Account Google che può essere utilizzato da un'applicazione per accedere alle API di Google in modo programmatico tramite OAuth 2.0. Non è necessaria un'autorizzazione umana, ma viene utilizzato un file della chiave accessibile solo dalla tua applicazione.
Prima di leggere di più sugli account di servizio, considera l'alternativa molto più semplice e altamente consigliata rispetto all'implementazione del flusso delle applicazioni installate con OAuth 2.0. Questo approccio richiede che un utente autorizzi manualmente l'applicazione a generare un token di aggiornamento, ma questa operazione deve essere eseguita solo una volta, dato che questi token non scadono mai.
Stai ancora leggendo? Ok, puoi implementare un account di servizio in uno dei seguenti modi:
- Se gli utenti risiedono su domini diversi, implementa l'utilizzo di un account di servizio come utente di Campaign Manager 360. Ciò ti consente di connetterti a più account di proprietà di diverse agenzie creando un nuovo profilo utente su ciascun account e associandoli tutti a un unico account di servizio. Questo è il modo migliore per utilizzare gli account di servizio con Campaign Manager 360.
- Se gli utenti risiedono in un singolo dominio di tua proprietà, implementa la delega a livello di dominio. In questo caso, devi disporre dell'accesso come amministratore a un dominio registrato con G Suite. Per ricevere assistenza per G Suite e / o la configurazione del dominio, visita la pagina di assistenza di G Suite.
Prerequisiti
Per implementare un account di servizio come utente di Campaign Manager 360, seleziona la scheda Utente Campaign Manager 360. Per implementare la delega a livello di dominio, seleziona la scheda Delega di seguito.
Devi avere accesso a un account Campaign Manager 360 in cui è abilitato l'accesso all'API.
- Devi avere accesso a un account Campaign Manager 360 in cui è abilitato l'accesso all'API.
- Devi disporre dell'accesso come amministratore a un dominio registrato con G Suite.
- Devi avere un profilo utente Campaign Manager 360 collegato a uno o più account all'interno del tuo dominio registrato su G Suite. Non è possibile utilizzare profili utente collegati ad account di altri domini, ad esempio gmail.com.
Configurazione e utilizzo di un account di servizio
Per eseguire l'implementazione utilizzando un account di servizio come utente di Campaign Manager 360, seleziona la scheda Utente di Campaign Manager 360. Per implementare la delega a livello di dominio, seleziona la scheda Delega di seguito.
- Genera una chiave dell'account di servizio nella console API di Google.
Attenzione: è importante proteggere il file della chiave che concede a un account di servizio l'accesso ai servizi Google per i quali è stato autorizzato. - Associa il profilo utente Campaign Manager 360 all'indirizzo email dell'account di servizio ottenuto nel passaggio precedente, come descritto nell'articolo del Centro assistenza Gestire l'accesso degli utenti.
- Implementa il flusso OAuth 2.0 server-server nella tua applicazione utilizzando l'account di servizio appena creato. Per ulteriori informazioni, consulta la sezione degli esempi.
- Genera una chiave dell'account di servizio nella console API di Google.
Attenzione: è importante proteggere il file della chiave che concede a un account di servizio l'accesso ai servizi Google per i quali è stato autorizzato. Ciò è particolarmente vero per il flusso di delega a livello di dominio grazie al controllo a livello di dominio di G Suite che consente all'account di servizio di impersonare qualsiasi utente nel dominio. Inoltre, è buona norma consentire agli account di servizio di accedere a una sola API di Google ciascuno (utilizzando il campo "ambito" descritto nel passaggio successivo). Si tratta di una misura preventiva per mitigare la quantità di dati a cui un utente malintenzionato può accedere nel caso in cui il file di chiavi di un account di servizio venga compromesso. - Delega l'autorità a livello di dominio a questo account di servizio per consentirgli di impersonare gli utenti all'interno del dominio. Quando richiesto, fornisci i seguenti ambiti API:
Ambito Significato https://www.googleapis.com/auth/dfatrafficking
Accesso in lettura/scrittura alla gestione del traffico di Campaign Manager 360. https://www.googleapis.com/auth/dfareporting
Accesso in lettura/scrittura ai report di Campaign Manager 360. https://www.googleapis.com/auth/ddmconversions
Accesso in lettura/scrittura alle conversioni offline di Campaign Manager 360. - Implementa il flusso OAuth 2.0 server-server nella tua applicazione utilizzando l'account di servizio appena creato. Per ulteriori informazioni, consulta la sezione degli esempi. Ricorda che dovrai fornire un account da impersonare, che deve appartenere al dominio per cui al tuo account di servizio è stata delegata l'autorità a livello di dominio nel passaggio precedente.
Per ricevere assistenza per G Suite e / o la configurazione del dominio, visita la pagina di assistenza di G Suite.
