Is there a way to transfer the VKontakte dialogue?

Question

In contact with

My interlocutor and I have a rather important dialogue. From my side, the dialogue was completely cleared, but from the side of the interlocutor, logically, it remained (accordingly, I can’t read anything from it). The dialogue is very big. Is it possible to somehow transfer the dialogue from the interlocutor back to yourself? It is best to return to VK, but maybe, if there is a way, then get a plain text file with messages. Thank you!

Answer 1

Back to VK - only if forwarded.
to a file - unload all messages via api.
