DESCO Balance Bot Script

Setting up Locally:

  • You need Python 3 installed on your computer

Install the following Python dependencies:

pip install requests python-dotenv

Rename the .env.sample file to .env file:

mv .env.sample .env

Setting up the Telegram bot:

  1. Open Botfather https://t.me/botfather and follow the instructions to create your bot (e.g, Desco Balance Bot). You will get a telegram bot token.
  2. Copy and add it to TELEGRAM_BOT_TOKEN in the .env file.
  3. Send a hi/hello chat to your new bot.
  4. Open this URL in your browser https://api.telegram.org/bot{TELEGRAM_BOT_TOKEN}/getUpdates
  5. Copy the chat id value and add it to the TELEGRAM_CHAT_ID in the .env file.

Run the script:

python check_balance.py

Output:

/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/urllib3/connectionpool.py:1097: InsecureRequestWarning: Unverified HTTPS request is being made to host 'prepaid.desco.org.bd'. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#tls-warnings
  warnings.warn(

(True, 'Telegram sent')

Ignore the SSL warning for now (I will update it later); you should see (True, 'Telegram sent`)

And receive a message in your Telegram app.

Known issues:

It is possible that behind the scenes, DESCO is using multiple endpoints for quering various Meter types.

The endpoint this script is using is:

https://prepaid.desco.org.bd/api/unified/customer/getBalance?accountNo=

So please test this endpoint with your DESCO account and first verify that this is working for your meter.
