How to Extract Plain Text from an Email Using the Gmail API

May 21, 2021

Are you looking to efficiently extract plain text from emails sent to your Gmail account? If so, you’re in the right place! In this article, we’ll walk you through the steps to make use of the Gmail API for this purpose. With our guidance, you’ll be able to navigate through the complexities of programming with ease.

Understanding the Gmail API

The Gmail API allows developers to interact programmatically with Gmail mailboxes and send email. This can include tasks like retrieving emails and processing their content. To illustrate this process, think of the API as a waiter in a restaurant: you request your meal (data) and the waiter (API) brings it to your table ( application).

Steps to Extract Plain Text

Step 1: Set Up Your Project
Get started by creating a new project in the Google Developer Console. Enable the Gmail API for your project.
Step 2: Authenticate Your Application
You’ll need to set up OAuth 2.0 credentials to access the Gmail API. This is similar to getting a key to your house; the key (credentials) is necessary to unlock (access) your home (Gmail).
Step 3: Install Required Libraries
For Python, you will need to install the Google client library using pip. Run the following command:
```
pip install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib
```

Step 4: Write the Code to Access Emails

Here’s an example of how to fetch emails and extract plain text:


from google.oauth2.credentials import Credentials
from googleapiclient.discovery import build

# Authenticate and build the service
creds = Credentials.from_authorized_user_file('token.json')
service = build('gmail', 'v1', credentials=creds)

# Fetch the email
email_id = 'YOUR_EMAIL_ID'
email = service.users().messages().get(userId='me', id=email_id).execute()

# Access plain text
plain_text = email['payload']['parts'][0]['body']['data']
print(plain_text)

In this example, the code serves as a bridge to communicate with the Gmail API, retrieve emails, and extract the text content seamlessly.

Step 5: Run Your Project
Execute your Python script to see the extracted text from the email. If all goes well, you should see the plain text output in your console!

Troubleshooting Tips

If you encounter a 403 Forbidden error, make sure your credentials are valid and the Gmail API is enabled for your project.
In case you get a 404 Not Found error, double-check the email ID you provided.
If the downloaded email does not contain text, ensure that the email you’re trying to access is in plain text format and not an HTML version.
