Before you can use the Gmail API to read emails, you need to authenticate with OAuth 2.0. This ensures secure access to user data and complies with Google's security standards.

3. Handling Access Tokens

Once authenticated, you'll receive an access token that allows you to make authorized requests to the Gmail API. It's crucial to handle these tokens securely and refresh them as needed.

The Gmail API offers various methods to fetch email messages, including getting a specific message, listing messages in a user's mailbox, or searching for messages based on specific criteria.

5. Parsing Email Content

When reading emails with the Gmail API, you'll need to parse the email content effectively. This involves extracting relevant information such as the subject, sender, recipients, body, and any attachments.

Gmail organizes emails into labels (similar to folders) and threads (conversations). Understanding how to work with these concepts through the API is key to efficient email management.
