Authentication Options

The simplest way to connect Google Calendar is by using xpander’s built-in authentication:
  1. In Xpander Chat, open the agent’s settings and click Add skill.
  2. Search for Google Calendar and select it.
  3. Click Sign in with Google Calendar.
  4. Grant xpander permission to access your account.
  5. Your Google Calendar integration is now ready to use.
This method is recommended for most users. xpander securely manages your OAuth tokens without exposing any credentials.

Give an agent the Google Calendar skill

Once Google Calendar is connected, any agent you can edit may be given the skill: open the agent’s settings, click Add skill, and choose Google Calendar. The skill panel lists the Google Calendar actions by group. Enable only the groups the agent needs, and mark the actions that should wait for a named person’s sign-off under These actions need approval. Which skills exist for your organization, and who may add them, is decided by your admins; see Skills.
