Help CenterUsers can send two types of media as messages -
-
Only Media file
-
Media file with a text
For the first case where the user only sends a Media File, Dialogflow receives the URL of the sent media.
For the case where the user sends Media File along with a text, the URL of the sent media is sent by adding it along with the text.
To handle URLs as user queries in Dialogflow, use RegExp (Regular Expression) type entity to capture such queries.

This will only match with URL with "fb" as a domain name. e.g. - https://fb.com/page/2928
RegExp to match URL of media sent by end-user
