The message updates you receive via <code>getUpdates</code> or your webhook will contain the chat ID for the specific message. It will be contained under the <code>message.chat.id</code> key.

This seems like the only way you are able to retrieve the chat ID. So if you want to write something where the bot initiates the conversation you will probably have to store the chat ID in relation to the user in some sort of key->value store like MemCache or Redis. 

I believe their documentation suggests something similar here, <a href="https://core.telegram.org/bots#deep-linking-example">https://core.telegram.org/bots#deep-linking-example</a>. You can use deep-linking to initiate a conversation without requiring the user to type a message first.

I created a bot to get User or GroupChat id,
just send the <code>/my_id</code> to telegram bot <code>@get_id_bot</code>.

It does not only work for user chat ID, but also for group chat ID.

To get group chat ID, first you have to add the bot to the group,
then send <code>/my_id</code> in the group.

<a href="https://telegram.me/get_id_bot" rel="noreferrer">Here</a>'s the link to the bot.

There is a bot that echoes your chat id upon starting a conversation.

Just search for <code>@chatid_echo_bot</code> and tap <code>/start</code>. It will echo your chat id.

Another option is <code>@getidsbot</code> which gives you much more information. This bot also gives information about a forwarded message (from user, to user, chad ids, etc) if you forward the message to the bot.

First, post a message in a chat where your bot is included (channel, group mentioning the bot, or one-to-one chat). Then, just run:

<pre class="lang-sh prettyprint-override"><code>curl https://api.telegram.org/bot&lt;TOKEN&gt;/getUpdates | jq

Feel free to remove the <code>| jq</code> part if your dont have jq installed, it's only useful for pretty printing. You should get something like this:

<a href="https://i.stack.imgur.com/ISf1E.png" rel="noreferrer"><img src="https://i.stack.imgur.com/ISf1E.png" alt="enter image description here"></a>

You can see the chat ID in the returned json object, together with the chat name and associated message.

Using the Perl API you can get it this way: first you send a message to the bot from Telegram, then issue a getUpdates and the chat id must be there:

<pre><code>#!/usr/bin/perl

use Data::Dumper;
use WWW::Telegram::BotAPI;

my $TOKEN = 'blablabla';
my $api = WWW::Telegram::BotAPI-&gt;new (
 token =&gt; $TOKEN
) or die "I can't connect";

my $out = $api-&gt;api_request ('getUpdates');
warn Dumper($out);
my $chat_id = $out-&gt;{result}-&gt;[0]-&gt;{message}-&gt;{chat}-&gt;{id};
print "chat_id=$chat_id\n";
</code></pre>

The id should be in chat_id but it may depend of the result, so I also added a dump of the whole result.

You can install the Perl API from <a href="https://github.com/Robertof/perl-www-telegram-botapi" rel="noreferrer">https://github.com/Robertof/perl-www-telegram-botapi</a>. It depends on your system but I installed easily running this on my Linux server:

<pre><code>$ sudo cpan WWW::Telegram::BotAPI
</code></pre>

Hope this helps

Straight out from the <a href="https://core.telegram.org/bots#deep-linking-example" rel="nofollow noreferrer">documentation</a>:

Suppose the website example.com would like to send notifications to its users via a Telegram bot. Here's what they could do to enable notifications for a user with the ID 123.

<ol>
<li>Create a bot with a suitable username, e.g. @ExampleComBot</li>
<li>Set up a webhook for incoming messages</li>
<li>Generate a random string of a sufficient length, e.g. $<code>memcache_key = "vCH1vGWJxfSeofSAs0K5PA"</code></li>
<li>Put the value 123 with the key $memcache_key into Memcache for 3600 seconds (one hour)</li>
<li>Show our user the button <a href="https://telegram.me/ExampleComBot?start=vCH1vGWJxfSeofSAs0K5PA" rel="nofollow noreferrer">https://telegram.me/ExampleComBot?start=vCH1vGWJxfSeofSAs0K5PA</a></li>
<li>Configure the webhook processor to query Memcached with the parameter that is passed in incoming messages beginning with <code>/start</code>. If the key exists, record the chat_id passed to the webhook as telegram_chat_id for the user 123. Remove the key from Memcache.</li>
<li>Now when we want to send a notification to the user 123, check if they have the field <code>telegram_chat_id</code>. If yes, use the <code>sendMessage</code> method in the Bot API to send them a message in Telegram.</li>
</ol>

<pre><code>$response = {

 &quot;message&quot;:{
 &quot;message_id&quot;:1665,
 &quot;from&quot;:{&quot;id&quot;:108177xxxx,&quot;is_bot&quot;:false,&quot;first_name&quot;:&quot;Suresh&quot;,&quot;last_name&quot;:&quot;Kamrushi&quot;,&quot;language_code&quot;:&quot;en&quot;},

 &quot;date&quot;:1604381276,
 &quot;text&quot;:&quot;1&quot;

</code></pre>
So you can access chat it like: 
$update[&quot;message&quot;][&quot;chat&quot;][&quot;id&quot;]
Assuming you are using PHP.

Extending @Roberto Santalla answer and if you prefer to use Telegram API together with <code>javascript</code> and <code>axios</code> library then you might want the following:
<pre><code>const method = 'get'

const headers: any = {
 'Access-Control-Allow-Origin': '*',
 'Content-Type': 'application/json',
 timestamp: +new Date(),
}

const options = { headers: { ...headers } }

const urlTelegramBase =
 'https://api.telegram.org/bot123456:ABCDEF'

const urlGetUpdates = `${urlTelegramBase}/getUpdates`
const username = 'user_name'

const {
 data: { result: messages },
} = await axios[method](urlGetUpdates, options)

const chat_id = messages.find(
 messageBlock =&gt; messageBlock.message.chat.username === username
).message.chat.id

console.info('chat_id': chat_id)
