how to open link in a new tab in the messenger bot platform

there's 2 types of postback buttons :-> "url" and the normal postback

is there anyway to use the normal postback for opening a url

the reason for not using the "url" that my url is not static

so I have to make some manipulation on the url before opening it,

Solution

You can generate dynamically your button object that opens the URL, per your needs.
