Our group chat component does not have any mechanism of message deletion/removal/retraction. In the case of group chats, you need to consider not only the removal of the message from the message archive of the group chat but also removal from a local message history that is stored by the XMPP clients.

A linked specification is not a standard, not even an experimental standard as it is not posted at https://xmpp.org/extensions/.

We are considering adding this feature (message retraction) in the future and most likely we will follow https://xmpp.org/extensions/xep-0424.html which is an experimental XEP (experimental specification which may become an extension of XMPP protocol).

Thank you for your reply. Yes, we wanted to delete the message in both archived messages in server and in XMPP clients. For clients, we can do some workaround to delete the message for now, but we don't know how to delete the message from archived messages. While we're waiting for the Xep-0424 to be implemented, would you please advise if there's a way to delete the message from archived messages (e.g. using a rest API, or accessing to database to look for the message and delete it)?

Hi again,

Also, would you please check and confirm if server already supports https://xmpp.org/extensions/xep-0425.html?

Many thanks, Trung

No, the server does not have support for this XEP. This XEP is still experimental and the last version was published on the 28th of January 2020, so it is not even a month old.

Thank you for your kind support!
