  • The API may have different methods for creating shareable links or access tokens for certain files or folders. These links or tokens contain information that allows other people to access the shared files.
  • Once the links or access tokens have been generated, users can share them via email, messaging apps, or their application interfaces.
Note: The particular implementation details, endpoints, and methods for sharing files can vary significantly depending on the cloud storage API used. The API provider’s detailed documentation will explain and guide you on how to utilize their API for file sharing and what endpoints or methods are available for these actions.
