Google Slides

Google Slides is a presentation tool developed by Google.

Authentication Types

Google Slides supports 2 authentication methods:

• OAuth - Create your own Google Cloud OAuth app. Every user connects with their Google account.

  • Pros: Full control, per-user tracking, production-ready
  • Cons: Requires Google Cloud Console setup

• Server App - Use a Google Cloud service account for server-to-server authentication.

  • Pros: No user interaction needed, good for automated workflows
  • Cons: More complex setup, requires domain-wide delegation for accessing user data
