  2. Enable Cloud Datastore API: In the Google Cloud Console, make sure that the Cloud Datastore API is enabled for your project. This API allows your application to interact with Cloud Datastore.

  3. Service Account Access: Grant the Service Account associated with your application the necessary permissions to access Cloud Datastore. Assign the appropriate roles, such as Cloud Datastore User or Cloud Datastore Viewer, to the Service Account.

  4. Download and Secure Key: Download the JSON key file generated for the Service Account. Safeguard this key file as it contains essential credentials for authenticating your application's access to Cloud Datastore.
