What is a Telegram webhook and how to set it up

Telegram is the famous cloud-based mobile and desktop messaging app with a focus on security and speed. In today’s blog post we’re going to talk about the Telegram webhook, how to set one up and how to use Telegram webhooks with other tools.

In this post, you’ll learn all about Telegram webhooks, and how to create them and use them with other tools. 

Ready, Steady, Go!

What is a Telegram webhook? 

The Telegram Webhook allows different applications and platforms to communicate and share data through the use of messages.

This communication occurs in real-time and is accomplished through the use of a Webhook Uniform Resource Locator (URL).

Using a Telegram Webhook Integration lets you share useful data with other third-party applications.

Creating webhooks is really easy.

How to set it up?

Firstly, setting up a Telegram webhook is really easy. 

Moreover, here is what Telegram offers in terms of APIs for developers:

• the Bot API: allows you to easily create programs that use Telegram messages for an interface;
• the Telegram API and TDLib allow you to build your own customized Telegram clients.

Finally, here are the steps to follow to create a Telegram webhook: 

1. Obtain the Authorization Token
2. Set Up your Google Spreadsheet
3. Create a Loading Dock
4. Store the Links in Variables
5. Set Up the Webhook, Bot and the POST Requests

Moreover, you can learn more details about setting up Telegram Webhooks and the BOT API. 

What are the main benefits of using a Telegram webhook?

Firstly, using ta Telegram Webhook has lots of benefits:

• Excellent choice if you need a simple solution for connecting to other apps 
• An ideal choice for embedded messages  as well as automated messages
• Allows you to receive timely notifications on your phone and laptops

How to use your Telegram webhook with other tools

Firstly, it’s important to remember that  Telegram offers two different API solutions for developers.  

For this example, we’re going to be using the Bot API. Learn more about the Telegram API options. Domotz is a network monitoring software and we also have an integration with Telegram. You can use a Telegram webhook to create a contact channel on Domotz to receive network and device events as alerts on Telegram.

How to use a Telegram webhook with Domotz

Domotz is able to send alerts directly to Telegram. This is pretty unique if compared to other network monitoring software.

Setting up the Domotz and Telegram webhook integration is super fast and easy. 

• Step1: You’ll need your Telegram API token to set up a  Telegram webhook on Domotz. 

• Step 2:  you can start receiving Domotz alerts on Telegram by obtaining a chat ID for a chat or a group where your Telegram bot is in and where you want to receive the messages.

Set up your first Telegram webhook in Domotz. This will alert you of all the events that you want to monitor.

To learn more about the creation of the Telegram bot API token and how to obtain a Telegram Chat ID you should read our user guide!

What does webhook actually mean?

In case you’re interested in learning more about webhooks. We thought it would be useful to cover what exactly webhooks are and where they came from. 

The term “webhook” was coined by Jeff Lindsay in 2007 from the computer programming term hook. It has been gaining popularity over the years, and it is an important concept on the journey of a programmer.

A webhook is one of a few ways in which web applications can communicate with each other. In other words, it’s a way to automatically send messages or information between other web applications It allows users to send real-time data from one application to another mainly whenever a given event occurs. 

In web development, a webhook is a method of augmenting or also altering the behavior of a web page or web application with custom callbacks. The format is usually JSON. The request is done as an HTTP POST request.

We can also say that webhooks are “user-defined HTTP callbacks”.

Let’s use a real-life example to understand how webhooks function: 

Firstly, go to Github and drop a URL in a dedicated textbox (for their code post webhook).  

Now, when you post your code to Github, it will HTTP POST to your chosen URL with details about the code post.

Moreover, let’s try another example, using an online purchase. When you receive a message from your credit card app, that is app integration in action.

Webhooks today offer a lot of value as an instant notification mechanism.

Have specific events you care about? 

Use a webhook for those events and you’ll have the power and flexibility to integrate that event stream into your life.

Before we better understand how Telegram webhooks work, let’s define the word “event”.

Events are human triggered actions on an app. 

For example, sending messages to someone when a specific alert is triggered. 

Data is attached to each of these events. On Telegram, when you send a message to a bot, the time stamp, your user ID, your message ID and your message are all part of the data that gets generated.

Ready to try your first Telegram webhook?

If you are looking for an easy way to communicate with other applications, the Telegram webhook is for you.  

For instance, you can use the Telegram webhook with Domotz to receive alerts about network and device events from Domotz.

php - How to set Telegram bot webhook?

Asked 5 years, 10 months ago

I'm developing a Telegram bot, and I want to set the webhook to my domain's URL. I've already generated a self-signed certificate following the Telegram's guide. However, I'm not able to set the webhook. I've searched previous answers and found this one, but it doesn't work to me. Can anybody explain me how to upload the SSL certificate and set the webhook?

• php
• ssl
• telegram
• webhooks
• telegram-bot

https://api.telegram.org/bot{my_bot_token}/setWebhook?url={url_to_send_updates_to} 

For instance:

https://api.telegram.org/bot123456:ABC-DEF1234ghIkl-zyx57W2v1u123ew11/setWebhook?url=https://www.example.com 

https://api.telegram.org/bot{my_bot_token}/setWebhook?url= 

response:

{"ok":true,"result":true,"description":"Webhook was deleted"} 

https://api.telegram.org/bot{my_bot_token}/getWebhookInfo 

I created a file on my server for conveniently setting up telegram webhooks.

You can use the same file on your server.

This should be on the same server from which you wish to run the Telegram Bot

1. Drop this file on the same server you wish to host you bots
2. Ensure the mime-type for .pem is enabled on your webserver
3. Browse to this page on our server
4. Fill the form with your BOT_TOKEN and chosen PORT
5. Upload your certificate file
6. Submit the form

You will get a successful result:

{"ok":true,"result":true,"description":"Webhook was set"}

Register the bot with @BotFather, install WebHook

Bot registration takes place without any necessary skills, by interacting with the "Father of Bots" @BotFather.

The sequence of actions for creating any bot is the same:

Open @BotFather and run it (Start). In the list of suggested commands, select: /newbot - create a new bot , click on this command, or enter it manually in the message field. You will be prompted to specify what the bot will be called, in the future the name of the bot can be changed . Enter a name in the message entry field. Next, you will be prompted to enter a name by which the bot will be available to users. Write the name using the Latin alphabet, numbers and underscores. Another important condition is that the name must end with "bot". You can also capitalize "Bot", or "_bot" or "_Bot". nine0003

If everything went without comment from @BotFather , then as a result you will be displayed on the Token API screen, if you don’t use it right away, then you can write it down somewhere. You can also request it again if you forgot or lost it. You can edit the bot from @BotFather, to do this, request a list of your bots /mybots , select the desired bot from the list and then, if necessary, you can edit its information, for this, select 9 in the bot menu0009 Edit Bot :

1. Name - Bot name

2. About - What can this bot do? (displayed when opening a bot in the middle of the screen)

3. Description - Description (available when viewing the Bot profile)

4. Botpic - Picture - Bota logo

5. 9000 - Set call in the dialogue with the bot command / )

Please note that it is not possible to change the bot name (@) in the settings.

* * *

Methods for interacting with the Bot API

There are two mutually exclusive ways to get updates for the bot - getUpdates and webHook. Incoming updates are stored on the Telegram server until the bot receives them, but they will not be stored for longer than 24 hours. nine0003

Regardless of which option you choose, you will get JSON-serialized objects (WIKI) as the result.

 https://api. telegram.org/botYOUR_TOKEN/setwebhook?url=https://YOUR_DOMAIN/bots/index.php 

 {"ok":true,"result":true,"description":"Webhook was set"} 

 https://api.telegram.org/bot YOUR_TOKEN/METHOD_NAME 

 updater.start_webhook(listen='0.0.0.0', port=8443, url_path='TOKEN', key='private key', cert='cert.pem', webhook_url='https://example.com:8443/TOKEN') nine0143 
 Reverse proxy + built-in server 
 webhook  .  
 To solve this problem, you can use a reverse proxy such as  nginx  or  haproxy  , or you can also use  Heroku  . 
 
 In this model, the reverse proxy (  nginx  ) listens on the public IP address, accepts all webhook requests, and forwards them to the correct instance of the locally running webhook servers built into  python-telegram-bot  . The reverse proxy also performs SSL termination, i.e. decrypts the HTTPS connection, so the webhook servers receive the already decrypted traffic. These servers can run on any port, not just the four ports allowed by Telegram, as Telegram server only connects directly to the reverse proxy server. nine0003 
 Depending on which proxy is being used, the implementation will look slightly different. Several possible settings are listed below. 
 
 Using 
 webhook  on Heroku.  
 On Heroku, webhooks can be used on a free plan, because it will automatically manage downtime. A reverse proxy will be configured for the Heroku user and a runtime will be created. From this environment, you will need to extract the port that the bot should listen on. Heroku manages SSL on the proxy side, so you don't need to create a certificate yourself. nine0003 
 import os TOKEN="TOKEN" PORT = int(os.environ.get('PORT', '8443')) updater = Updater(TOKEN) # add handlers updater.start_webhook(listen="0.0.0.0", port=PORT, url_path=TOKEN, webhook_url="https://.herokuapp.com/" + TOKEN) updater.idle() 
 
 Using 
 nginx  with the same domain/port for all bots  
 All bots set their URL to the same domain and port but with a different  url_path  . The server built into  python-telegram-bot  usually starts at  localhost  or 127.0.0.1, the port can be anything. 
  Note  
 : If there is no domain associated with the server, then  example.com  can be replaced with an IP address. 
 
 Sample code for starting the bot: 
 
 updater.start_webhook( listen='127.0.0.1', port=5000, url_path='TOKEN1', webhook_url='https://example.com/TOKEN1', cert=open('cert.pem', 'rb') ) nine0143 
 Configuration example for  nginx  with two configured bots (important parts of the config are shown): 
 
 server { listen 443 ssl; server_name example.com; ssl_certificate cert.pem; ssl_certificate_key private.key; location /TOKEN1 { proxy_pass http://127.0.0.1:5000/TOKEN1/; } location /TOKEN2 { proxy_pass http://127.0.0.1:5001/TOKEN2/; } } 
 
 Using 
 haproxy  with one subdomain per bot. nine0075 
 With this approach, each bot is assigned its own subdomain. If the server has a domain  example.com  , then you can create subdomains for example:  bot1.example.com  ,  bot2.example.com  , etc. You will need one certificate for each bot with the FQDN set to the corresponding subdomain. The server built into  python-telegram-bot  usually starts at  localhost  or 127.0.0.1, the port can be anything. nine0003 
  Note  : You must have a domain associated with the server's IP address. 
 
 Sample code for starting the bot: 
 
 updater.start_webhook( listen='127.0.0.1', port=5000, url_path='TOKEN', webhook_url='https://bot1.example.com/TOKEN, cert=open('cert_bot1.pem', 'rb') ) 
 
 Configuration example for  haproxy  with two configured bots (reduced to the important parts of the config) . Again, the FQDN of both certificates must match the value of  ssl_fc_sni  . In addition, files  .pem  are the combined files  private.key  and  cert.pem  . 
 
 frontend public-https bind 0.0.0.0:443 ssl crt cert_key_bot1.pem crt cert_key_bot2.pem option httpclose use_backend bot1 if { ssl_fc_sni bot1.example.com } use_backend bot2 if { ssl_fc_sni bot2.example.com } backend bot1 http mode option redispatch server bot1.example.com 127.0.0.1:5000 check inter 1000 backend bot2 http mode option redispatch server nine0143 
 Tailor-made solution built on streams. 
 
 It is not necessary to use the Embedded Web Server. If you choose to go this route, you should not use the  Updater  class. Extension module  telegram.ext  has been developed with this option in mind, so class  Dispatcher  can be used to receive/send and filter/sort messages. True, some things will have to be done manually.
