How to access to the folder object using the SharePoint API?

Hi All,

Can you please guide me on how to access to the folder object using the SharePoint API?

For example : Let suppose I have folder structures like below :

• Corporate is parent folder .
• Sub folder for corporate is a) India b) US
• Sub folder of India is a) ICICI b) Mastercard

I want to add user(ABC) for only one folder that is master Card folder . Is there any API related to Kava for SharePoint ?

Please find the attachment for your reference.

Thanks in Advance!

Regards,

Pallavi.
