Yahoo IMAP Authentication using OAuth2 Access Token

See more Yahoo Mail Examples

Demonstrates how to do IMAP OAuth2 authentication for Yahoo (or any other IMAP mail server supporting OAuth2 authentication). This example assumes an OAuth2 access token was previously obtained. Chilkat2-Python

import sys
import chilkat2

success = False

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# See Get Yahoo Mail OAuth2 Access Token for Desktop App 
# for sample code showing how to obtain a Yahoo Mail access token.

# In this example, our access token was previously saved to the following file which contains JSON like this:
# {
#   "access_token": "kCVQdnOdul...LHucA--",
#   "refresh_token": "AIenVXETSo0jklFBVkPS8vVm8E.Ej9ToRG.xDbDYmZ65WIs5t6CZhDrD",
#   "expires_in": 3600,
#   "token_type": "bearer",
#   "xoauth_yahoo_guid": "HGDQCVF5JB4YDOWHITQJFBHCWA"
# }

json = chilkat2.JsonObject()
success = json.LoadFile("qa_data/tokens/yahooMail.json")
if (success != True):
    print("Failed to load GMail access token file.")
    sys.exit()

accessToken = json.StringOf("access_token")

# Do OAuth2 authentication by using the access token as the password in the Login method below...
imap = chilkat2.Imap()

imap.Ssl = True
imap.Port = 993

# Connect to the Yahoo IMAP server.
success = imap.Connect("imap.mail.yahoo.com")
if (success == False):
    print(imap.LastErrorText)
    sys.exit()

# Indicate that XOAUTH2 authentication is to be used:
imap.AuthMethod = "XOAUTH2"

# Login
# Use the email address of the GMail account that granted authorization.
success = imap.Login("user@yahoo.com",accessToken)
if (success != True):
    print(imap.LastErrorText)

    print("Successfully authenticated with Yahoo IMAP using XOAUTH2!")
