Getting "Direct Link" for image in "Public Folder" to Embed Image in Website

[dplank]

Hello,

I read this article about "Public Folder" at https://my.pcloud.com/#page=public

So, I'm trying to get the "Direct Link" for the image stored in "Public Folder" using just pCloud API. I have tried the function getfilelink(file id) and it's getting me link to download file. But this link expire after some time. But I want to get the link, which I can use in my website forever. To use "Public Folder" I purchase the Monthly plan for PCloud but I'm not sure how can I get that link.
Also I noticed that link starts with "https://filedn.com" which is to be use in website.

Can you please somebody help. Its urgent!

Many thanks in Advance.!
