#### The problem
When working in small teams, it is crucial to get critical updates on errors or different statuses of CI\CD processes. Sometimes default email notifications are not enough, every member of the team is doing his best to complete his part of the current sprint so some emails can be missed out, especially if your team lacks a dedicated DevOps and someone else from the team do it part time.

#### The proposed solution
If some action requires an immediate reaction, the person which should react to it should be notified as fast as possible. Push notifications are pretty good solution to this job. There are many providers of such a service, but the one I found pretty easy to set up and use is 
[**Telegram Bot API**](https://core.telegram.org/bots/api).
Following [**this guide**](https://medium.com/javarevisited/sending-a-message-to-a-telegram-channel-the-easy-way-eb0a0b32968) by Paolo Montalto you will be able to:
1. Create a Telegram channel.
2. Create a Telegram bot and invite it to your channel.
3. Send your first Telegram message programmatically.

The next steps are pretty easy, After you've followed Paolo's guide, you'll be able to send messages by issuing a GET request to the following URL:
~~~js
https://api.telegram.org/bot[BOT_API_KEY]/sendMessage?chat_id=[MY_CHANNEL_NAME]&text=[MY_MESSAGE_TEXT]
~~~
Where as Paolo writes:
- **BOT_API_KEY** is the API Key generated by BotFather when you created your bot
- **MY_CHANNEL_NAME** is the handle of your channel (e.g. @my_channel_name)
- **MY_MESSAGE_TEXT** is the message you want to send (URL-encoded)
With the help of the mentioned above, configure your Jenkins pipeline to make a request to the Telegram Bot API, and send a job status to your channel.

Inside a ```post``` build action, in case of failure make a request to the API, use **curl** or any other tool.
~~~bash
post {
  failure {
    sh """
    #!/bin/bash
    curl https://api.telegram.org/bot<BOT_API_KEY>/sendMessage -d "chat_id=<MY_CHANNEL_NAME>&
    text=Jenkins build failed:\nProject: ${env.JOB_NAME}\n
    Build Number: ${env.BUILD_NUMBER}\nBuild URL:${env.PROJECT_URL}\n"
    """
  }
}   
~~~
Now on each job failure you will get the following push notification:

#### Conclusion
Try and experiment with different messages, we found this pretty helpful when we started our project and I hope some of you will find it helpful too. 


Delegate push notifications handling to someone else

#### What this blog is
It is a media that I will share my ideas, knowledge and some stuff I may find useful or interesting. 
I'm planning to write about **web development**, **DevOps** and more tech stuff.
On a moment of publishing of this article, the blog is still in development.
Currently I'm making it with **Next.js**, **TypeScript**, **Strapi** and **GraphQL**, I use **Heroku** for deployment, but more may be added when the blog will become stable.
I'm planning to keep changing it every once in a while, in order to practice my dev skills and just for fun.
