I would suggest making Snapchat the first term of the "API-snapchat" title and adding python to it, this repo wasn't there when I search "Snapchat API python"

I got this issue when running.

{"logged":false,"message":"أنت تستخدم إصدارًا من Snapchat لم يعد مدعومًا. يُرجى التحديث إلى أحدث إصدار للتطبيق لاستخدام Snapchat. شكرًا."}
You're using a version of Snapchat that's no longer supported. Please update to the latest version of the app to use Snapchat. Thank you.

I changed the user-agent of the header to the latest version:

'User-Agent': 'Snapchat/11.41.0.36 (iPhone9,3; iOS 14.4.1; gzip)',

But got another error saying:

{"logged":false,"message":"عفوًا! أنت تحاول الوصول إلى Snapchat بواسطة تطبيق خاص بجهة خارجية! يُرجى استخدام تطبيق Snapchat الرسمي بدلاً من ذلك لو سمحت . 👻"}

You're welcome! You're trying to access Snapchat with a third-party app! Please use the official Snapchat app instead, please. 👻
