Auto get mail in label gmail

You want to automatically retrieve emails from Gmail and apply a label to them. This can be achieved using Gmail's API and a programming language of your choice. Here's a step-by-step guide to help you get started:

Prerequisites:

Create a Gmail account and enable the Gmail API.
Create a project in Google Cloud Console and enable the Gmail API.
Create credentials for your project (OAuth client ID).
Install the Google API Client Library for your preferred programming language.

Step 1: Set up the Gmail API

Go to the Google Cloud Console and navigate to the API Library page.
Search for "Gmail API" and click on the result.
Click on the "Enable" button to enable the API.
Create credentials for your project by clicking on the "Create Credentials" button.
Select "OAuth client ID" and choose "Other" as the application type.
Enter a name for your client ID and authorized JavaScript origins.
Click on the "Create" button to create the credentials.

Step 2: Install the Google API Client Library

Install the Google API Client Library for your preferred programming language using the following commands:
- Python: pip install google-api-python-client
- Java: mvn install google-api-java-client
- Node.js: npm install google-api-library

Step 3: Write the code to retrieve emails and apply a label

Here's an example code snippet in Python using the Google API Client Library:

import os
import base64
from google.oauth2.credentials import Credentials
from googleapiclient.discovery import build

# Set up credentials
creds = Credentials.get_credentials()
service = build('gmail', 'v1', credentials=creds)

# Set up the label
label_name = 'your_label_name'

# Retrieve emails
response = service.users().messages().list(userId='me').execute()
messages = response.get('messages', [])

for message in messages:
    msg_id = message['id']
    msg = service.users().messages().get(userId='me', id=msg_id).execute()
    payload = msg['payload']
    headers = payload['headers']
    subject = [header['value'] for header in headers if header['name'] == 'Subject'][0]

    # Apply the label
    service.users().messages().modify(userId='me', id=msg_id, body={'labelIds': [label_name]}).execute()

This code retrieves emails from the inbox, applies a label to each email, and then prints the subject of each email.

Step 4: Run the code

Run the code using your preferred programming language. Make sure to replace your_label_name with the actual name of the label you want to apply.

Note: This code snippet is just an example and may need to be modified to fit your specific use case. Additionally, be aware of the Gmail API usage limits and ensure that your code complies with the terms of service.
