I am creating a dynamic link by passing the fields
st
,sd
andsi
now user has copied that link and pasting in the chat field on my website and I want to implement unfurling logic like slack and show the preview.When I try to get the
meta
tags of the link(shortened) I get the meta tags of page to which i will be redirected.But I want to show the data which i passed to
st
,sd
andsi
while creating the link.So how to do it?
Somehow slack and other chat platforms are able to get it but I am not getting that tag anywhere.
So where and how can I get that data.
Here is the example how slack shows the preview
