Storing the PDF Documents in the "OneDrive" Shared Folder from the asp.net web application

Hi,

I have developed a web application using c# and Asp.Net and Hosted in the Amazon Cloud environment.

From that application based on the backend data we will generate PDF Documents and save in a local folder.

But, now the client wants to store those PDF Documents in (Their Office 365 OneDrive account)"Office 365 OneDrive" Folder directly from the web application and an email need to be sent from the application by attaching that saved PDF Document.

I do not have any idea, i gone through internet but, i cant able to get any solution...

Please provide any idea/reference links or articles to Store the PDF Document directly to the OneDrive Folder and to retrieve the PDF file from the OneDrive Folder...Whether it is possible?

Thanks,

Hanife
