Resend bot¶
Description¶
The general idea is to ask questions within the Telegram group (let’s call it Target group) and get answers.
The group might be:
- Support Team
- IT Department of your company
- etc.
Technical specification¶
Chat ID¶
/thischat– returns id of current chat. It’s used for the identification of the Telegram group./myid– returns id of a user
Send message¶
The are following ways for sending message-reqest to the bot:
- In private chat with the bot: any message
- e.g. hello, how are you?, etc
- In another Telegram group (different from Target group): any message that starts with / and ends with @<name_of_the_>bot is used as a response to the Bot’s message
- e.g. /hey@super_bot, /please@request_bot, etc.
Get message¶
The Target group receives a copy of the message with a reference to the sender and the original message itself.
Response¶
- Users response to the bot, in so doing:
- The copy of the response is sent back to chat, which contains the original message.
- Response from Target group is anonymous by default, but could be customized.
Examples¶
- In the original chat from Ivan
/hey Answer to the Ultimate Question of Life, the Universe, and Everything? - In the Target group from @name_of_the_bot:
<a href="userlink">Ivan</a>: Answer to the Ultimate Question of Life, the Universe, and Everything? *msg:<message1>:<chat>* - In the Target group from @Deep_thought1:
Anybody knows the answer? - In the Target group from @Deep_thought2:
Let me think a little bit? - In the Target group from @Deep_thought1:
? - In the Target group from @Deep_thought2:
Ok, I found and checked the answer! - In the Target group from @Deep_thought2: In reply to Ivan: Answer to the Ultimate Question …
The answer is 42! - In the Original chat from @name_of_the_bot:
The answer is 42! *msg:<message2>*
