Tag/Mention other users through comment content by writing “@{UserName}…”

Product: PDFTron WebViewer

Product Version: 8.11

Please give a brief summary of your issue:


I would like to know if something exists/is planned to enable a user to tag another user, in order to notify it.
For instance, in a comment from an annotation, write “@{UserName}…”

Thank you.

Best Regards,


Hi Alex,

In WebViewer we can tag a user if the user data was set with the MentionsManager.setUserData API.
You can quickly test the functionality by creating a rectangle annotation in this particular showcase demo, then add a comment to the annotation starting with “@”.

Notifying the user by email would involve a server side implementation and is up to each SDK users’ own implementation.

Best Regards,
