telegram bot - Bot api, how i can get last message or chat history? -

i want implement functional user send me message , reply him (bot) latest message chat history.

as can see in telegram bot api documentation can use sendmessage send message user.

when receive message, chat or from parameter in json (depends if want answer person when it's group chat or not). can use id parameter of chat or from send message.

so first parameter sendmessage chat_id=message.chat.id

you don't need parse_mode, disable_web_page_preview , reply_markup example.

as want reply message of user may want set reply_to_message_id id of received message.

reply_to_message_id = message.message_id 

last not least, want set text parameter. if understand correctly, program send last received message.text user.

so want is, message, save it.

message oldmessage = message 

and when send message user use old messages text property text.

text = oldmessage.text 

alright sum here pseudocode of function happen receive message:

message oldmessage = null;  public void newmessage(message message){      int chat_id = message.chat.id;     int reply_to_message_id = message.message_id;      string text = "there no old message"; //fallback value      if(oldmessage != null){         text = oldmessage.text;     }      //send message in example has 3 parameters, , ignores      //not used ones     sendmessage(chat_id,text,reply_to_message_id);      oldmessage = message; //store received message future answering  } 

as store whole message in oldmessage set text send this:

string text = oldmessage.from.first_name+": "+oldmessage.text;
