How to download files from attachment id.

I need to get data from the attachment.
I have attachment id.
attachment url.

Can anyone please let me know how to read the data.

@SreekanthB I am assuming you want to access it via the Backend API?

Backend API: See this section in the docs. You will receive an URL, with which you can do a simple HTTP GET.

If it’s in CloudCode or the app, this is what you are looking for.
