Sending a notification to a topic in a telegram group

[Epigraphe]

Good day.
How to fix the script so that the telegram is sent not only to the group, but to the topic in this group?
In fact, topics are responses to a message, so I need to add “reply_to_message_id” to the script so that the final URL looks like

[URL]https://api.telegram.org/botToken/sendMessage?chat_id=-100xxxxx&reply_to_message_id=xxx&parse_mode=Markdown&text=[/URL]«Text»​

Unfortunately, I don't understand Java so I can't do it myself.

Can you please tell me how to add it?

Script from the well-known media_telegram.yaml

Thank you

We need to add just one line:

reply_to_message_id: XXX,

As a result, it will look like this:

sendMessage: function () {
var params = {
chat_id: Telegram.to,
reply_to_message_id: XXX,
text: Telegram.message,
disable_web_page_preview: true,
disable_notification: false

Hello, you can use below code on script, It's working and tested.

var Telegram = {
    token: null,
    to: null,
    message: null,
    proxy: null,
    threadId: null,
    parse_mode: null,

    escapeMarkup: function (str, mode) {
        switch (mode) {
            case 'markdown':
                return str.replace(/([_*\[`])/g, '\\$&');

            case 'markdownv2':
                return str.replace(/([_*\[\]()~`>#+\-=|{}.!])/g, '\\$&');

            default:

Спасибо, работает. Для ситуации, когда надо отправлять в разные чаты и, соответственно, топики - пока нашел решение в прописывании message_thread_id в Inventory URL A (например) и задании параметра в media type Telegram ThreadId: {INVENTORY.URL.A}. Как сделать это в поле Send To: чтобы скрипт парсил и id и message_thread_id - не разобрался
