[@KetanRathod-dm9ep]

It shows me error that enable to load request in lambda how to deal with it ??

[@KnowledgeAmplifier1]

Hello Ketan Rathod, if you are facing issue with request module import part , then that means the module is not available as part of lambda default execution env. Might be you are using Python 3.9 or some python version where request module is not available , to resolve the issue there are 2 options --
1)Use lambda deployment zip or Lambda Layer
For Lambda deployment zip , you can refer this --
ruclips.net/video/9hsdnLrx4iE/видео.html
For Lambda Layer , you can refer this --

2)Use Python 3.7 as execution env as done in this video.
Hope this will help in resolving issue .. Happy Learning
