By the way, when you've finished creating your cool bot, ping our Bot Support if you want a better username for it. Just make sure the bot is fully operational before you do this.

We need to use this bot to send a message, you first need to create a group, add some people, but the bot will be added to the list. Then sends the message in this group. Similar / hello @GZ_David_Bot
Then visit
https://api.telegram.org/botxxx:xxx/getUpdates
我们会获取到一个json
{
"ok" : true,
"result" : [{
"update_id" : xxx,
"message" : {
"message_id" : 4,
"from" : {
"id" : xxx,
"first_name" : "david",
"last_name" : "huang",
"username" : "davidhuang"
},
"chat" : {
"id" : -xxx,
"title" : "bot",
"type" : "group",
"all_members_are_administrators" : true
},
"date" : xxx,
"text" : "/hello @GZ_David_Bot",
"entities" : [{
"type" : "bot_command",
"offset" : 0,
"length" : 6

]
}
},
]
}
Here, we see a id, refers to the current group of id. We note of it. Then do the following curl.
botXXX: YYYY refers to the bot + token, be sure to add the prefix bot
chat_id is above id, attention is negative, there must be -
send content = my sample text
curl -X POST "https://api.telegram.org/botXXX:YYYY/sendMessage" -d "chat_id=-zzzzzzzzzz&text=my sample text"
Executed, this group would receive the news.
