Hi Community,

I’m looking for your thoughts and suggestions on how to implement this requirement efficiently at the code level.

Recently, I received a request where a binary file (CSV) — which is already being generated — needs to be uploaded to a SharePoint location provided by the client. The challenge is that the client's SharePoint site has restricted access, and I’m unsure how to handle authentication and file upload through code.

Could you please guide me on:

• How to programmatically authenticate and upload the file to SharePoint?
• What permissions or setup are required from the client side to enable access?
• Any best practices or recommended approaches for handling this kind of integration?

I’m a bit confused about the implementation details, so any insights would be greatly appreciated!
