Google Sheets API Error

Н̶а̶п̶и̶с̶а̶л̶ Скопировал код:

import httplib2
import os

from googleapiclient import discovery
from google.oauth2 import service_account

try:
    scopes = ["https://www.googleapis.com/auth/spreadsheets",]
    secret_file = os.path.join(os.getcwd(), "client_secret.json")

    spreadsheet_id = "..."
    range_name = "Sheet1!B3"

    credentials = service_account.Credentials.from_service_account_file(secret_file, scopes=scopes)
    service = discovery.build("sheets", "v4", credentials=credentials)

    values=service.spreadsheets().values().get(spreadsheetId=spreadsheet_id,range=range_name,).execute()

    print(values.get('values'))


except OSError as e:
    print(e)

Когда запускаю, выдает вот это:

Traceback (most recent call last):
  File "main.py", line 17, in <module>
    values=service.spreadsheets().values().get(spreadsheetId=spreadsheet_id,range=range_name,).execute()
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/googleapiclient/_helpers.py", line 134, in positional_wrapper

    raise HttpError(resp, content, uri=self.uri)
googleapiclient.errors.HttpError: <HttpError 400 when requesting https://sheets.googleapis.com/v4/spreadsheets/.../values/Sheet1%21B3?alt=json returned "Unable to parse range: Sheet1!B3". Details: "Unable to parse range: Sheet1!B3">

Когда сам перехожу по ссылке пишет:

{
  "error": {
    "code": 403,
    "message": "The request is missing a valid API key.",
    "status": "PERMISSION_DENIED"
  }
}

Как исправить???
