How to get all messages from a dialog in vk.com?

Question

PHP

Hello. I'm trying to figure out the messages.getHistory method, in particular while experimenting with their form for configuring settings. I can’t figure out where exactly to enter the id of the conversation (not a group, not a chat with a specific user, but a conversation where several users participate). I tried with the peer_id parameter (I entered both just id and, as in the documentation with 2000000000 (200000000013 for example)), I also tried to enter the conversation id in the user_id field ... In general, how to get a list of messages in a conversation correctly? Thanks to all.

Firstly, do not use the request generator built into the dock (it is buggy and requires you to specify an access_token)
Therefore, you need to directly manually (you can use the browser) create a get request in which you need to specify a peer_id equal to 2000000000 + conversation ID (not concatenation, but just addition). Also, be sure to specify the access_token (required with "messages" rights) and the version (at least 5.38, the latest one is better at the moment - 5.53)
