Getting user access_hash

[ghost]

Hi

I'm developing some customer service bot. People send Telegram messages to the service and the service needs to auto reply. But these people are not in the contact list of the service so I need to use TLInputPeerForeign to send a message to them. On receiving a message I can see the user_id but not the access_hash. How can I get the access_hash of a user?

Thx

You should use https://core.telegram.org/method/messages.getDialogs method.
It returns you users list

Related: How would I get the user access_hash for a UserForeign request if I have just the user_id and no message? (say I want to start a chat with a user not in contact list)

You cannot start chat with user not from contact list. You should add it to contact list first.

Hi,
How can we get channels messages without joining it (and so it wouldn't be added to the user's Dialogs)?
It's possible in the telegrams' apps, when you click on a channels username any where (@channel_user).
