How to know about all joined Supergroups?

[wowka1319]

If I'm not mistaken the only way to know a supergroup is joined is chatMemberStatus* in updateSupergroup.supergroup.status. But to find out about all joined ones I need to get all updateSupergroup. How can I make sure I have received all these updates?

There is no way to do this without loading full chat list.

When I get 404 for loadChats can I make sure I got updateNewChat for all joined supergroups already?

[levlam]

Yes, for all groups from the specified chat list.

[wowka1319]

updateNewChat for a supergroup contains required updateNewChat.chat.type.supergroup_id. Is it guaranteed I got updateSupergroup for it before?

See https://core.telegram.org/tdlib/getting-started.

Found the answer. Thanks a lot.

1. When a joined channel is deleted (by its admin or Telegram because of violations) will the subscriber's account received updateSupergroup?
2. Will updateSupergroup.supergroup.status be chatMemberStatusLeft in this case?

When a joined channel is deleted (by its admin or Telegram because of violations) will the subscriber's account received updateSupergroup?

Eventually, yes. The status can be Left or Banned.

If the app was off when deleting the channel and then it started, will that updateSupergroup be received?

[levlam]

The user will definitely know that the chat isn't accessible anymore sooner or later.

The user finds out that (after long being off) due to exactly updateSupergroup always? Or he has to remember about all chats before switch off and compare a new list after that?

[levlam]

updateSupergroup is sent when some field changes. I don't understand, what do you mean by "compare a list".
