i am doing script which every 10 minuties does that:

from google.oauth2.credentials import Credentials

from googleapiclient.discovery import build

import base64

from datetime import datetime

from dateutil import parser

from services.uploaded_files_service import UploadedFilesService

from repositories.uploaded_files_repository import UploadedFilesRepository

from services.dropbox_config_service import DropboxConfigService

from repositories.dropbox_config_repository import DropboxConfigRepository

from send_to_dropbox import send_files_to_dropbox

from models.session import AsyncSessionLocal

import asyncio

import re

SCOPES = [‘https://www.googleapis.com/auth/gmail.readonly’]

creds = Credentials.from_authorized_user_file(‘gmail_tokens.json’, SCOPES)

service = build(‘gmail’, ‘v1’, credentials=creds)

async def get_last_messages(uploaded_files_service: UploadedFilesService, dropbox_config_service: DropboxConfigService):

last_uploaded = await uploaded_files_service.get_last_uploaded()

messages = service.users().messages().list(userId=‘me’, maxResults=20).execute().get(‘messages’, 
)

msgs_dict = {}

for msg in messages:

msg_id = msg\['id'\]

await asyncio.sleep(1.5)

msg_data = service.users().messages().get(userId='me', id=msg_id, format='full').execute()

payload = msg_data\['payload'\]

parts = payload.get('parts', \[\])

headers = msg_data.get('payload', {}).get('headers', \[\])

date_header = next((h\['value'\] for h in headers if h\['name'\].lower() == 'date'), None)

attachments = \[\]

if date_header:

    dt = parser.parse(date_header)

    timestamp = dt.strftime("%Y-%m-%d %H:%M:%S")

else:

    timestamp = "unknown"

print(msg_id)

if str(timestamp) not in last_uploaded:

 for part in parts:

    mime_type = part.get('mimeType')

    body = part.get('body', {})

    data = body.get('data')

    html = ""


    \# HTML-содержимое

    if mime_type == 'text/html' and data:

        html = base64.urlsafe_b64decode(data).decode('utf-8', errors='replace')


    \# Вложения

    filename = part.get('filename')

    attachment_id = body.get('attachmentId')

    if filename and attachment_id:

            await asyncio.sleep(1.5)

            attachment = service.users().messages().attachments().get(

                userId='me', messageId=msg_id, id=attachment_id

            ).execute()

            file_data = base64.urlsafe_b64decode(attachment\['data'\])


            attachments.append({

                "filename": filename,

                "filedata": file_data

            })

 msgs_dict\[timestamp\] = {

        "message": html,

        "attachments": attachments

    }

print(msgs_dict.keys())

return await send_files_to_dropbox(msgs_dict, dropbox_config_service, uploaded_files_service)

async def process_new_messages():

async with AsyncSessionLocal() as session:

    uf_repository = UploadedFilesRepository(session)

    uf_service = UploadedFilesService(uf_repository)

    dc_repository = DropboxConfigRepository(session)

    dc_service = DropboxConfigService(dc_repository)

    await get_last_messages(uf_service, dc_service)

import asyncio

print(“Скрипт запущен”)

asyncio.run(process_new_messages())

This script takes 20 last messages, checks whether rhey are in database and takes their media. But after some time i get 429

googleapiclient.errors.HttpError: <HttpError 429 when requesting https://gmail.googleapis.com/gmail/v1/users/me/messages?maxResults=20&alt=json returned “User-rate limit exceeded. Retry after 2025-10-30T05:15:15.501Z”. Details: “[{‘message’: ‘User-rate limit exceeded. Retry after 2025-10-30T05:15:15.501Z’, ‘domain’: ‘global’, ‘reason’: ‘rateLimitExceeded’}]”>

I try after this time it says, but get this error again with new time, in average i should wait around 15 hours but it is too much

How can i avoid that??? I am sure I dont use 1000000 quotas in minute or 100 in second, as you can see I added delay before requests but it didnt help
