There are 2 methods in Telegram API that forward message:
- messages.forwardMessage
- messages.forwardMessages
I want to use forwardMessage method to forward a message from a channel, group or user to another one. Definition of this method is:
messages.forwardMessage#33963bf9 peer:InputPeer id:int random_id:long = Updates;
As you see this method has 3 input parameters:
peer that represents the channel, group or user that we forward message to. (Destination)id that is message_id.random_id that has internal use.
As we know the message_id is a unique number in a chat. so a message_id in a group has refers to a message that differs with the same message_id in other group.
So the main question is that how we determine the source peer of forwarding? Because the source peer is not determined by message_id.
P.S: My question is about methods in Telegram API, not Telegram Bot API.
There seems to an issue with ForwardMessageRequest which doesn't specify the source chat. Obviously message_id is not unique and through my tests I noticed wrong messages will be forwarded by just specifying the message_id. And I noticed message_id is not unique.
But the issue doesn't exist with ForwardMessagesRequest. Following is an example how to use the ForwardMessagesRequest version.
Forwarding Example:
Here is the code I used for testing (I am using Telethon for python, but it won't matter since it's directly calling telegram API):
source_chat = InputPeerChannel(source_chat_id, source_access_hash) total_count, messages, senders = client.get_message_history( source_chat, limit=10) for msg in reversed(messages): print ("msg:", msg.id, msg) msg = messages[0] print ("msg id:", msg.id) dest_chat = InputPeerChat(dest_chat_id) result = client.invoke(ForwardMessagesRequest(from_peer=source_chat, id=[msg.id], random_id=[generate_random_long()], to_peer=dest_chat))
