To use the Gmail API, you first need to set up a project on the Google Cloud Platform. This involves creating a new project or selecting an existing one.

Step 2: Enable the Gmail API

Once your project is set up, you need to enable the Gmail API for your project. This can be done through the Google Cloud Console.

Step 6: Set Up Authentication

Using the credentials you created, set up the authentication process. This involves specifying the scope of access your application requires.
