    You should add all field data you receive from the request callback but remove the hash field.
    Ex:

    `auth_date=1665991955
first_name=xxxxx
id=xxxxxx
last_name=xxxxx
photo_url=xxxxxxx
username=xxxxx`

    I try and succeed.

    It happened to me as well, I described it in My question. You might copy the response from this API: https://oauth.telegram.org/auth/get?bot_id=xxx sometimes the response works with the function, sometimes it doesn’t, and honestly, I don’t understand why. Try to print user to console and check if the two hashes match!

    What I have done is as follow:

    I changed my bot’s domain to https://www.w3schools.com/ and go to w3school online editor https://www.w3schools.com/js/tryit.asp?filename=tryjs_string_indexof for example, print user object to console (replace the javascript in the online editor with code bellow and then replace YOUR-BOT-NAME in the code with the name of your bot):

    <script async src="https://telegram.org/js/telegram-widget.js?21" data-telegram-login="YOUR-BOT-NAME" data-size="large" data-onauth="onTelegramAuth(user)" data-request-access="write"></script>
<script type="text/javascript">
  function onTelegramAuth(user) {
    console.log(JSON.stringify(user, null, 2));
  }
</script>
    1. press f12, go to console tab and then login with widget. Check the data printed on the console with your function.
