WebApp Repair
11 USD Hello!
Problem Description:
I developed a Telegram bot based on the python-telegram-bot (version 20+) library, which has a button with web_app=WebAppInfo(url=...). This button opens a page (WebApp) hosted on GitHub Pages at https://danza13.github.io/telegram-webapp/.
What Happens:
- When the page opens inside Telegram (via the "Select date and time" button), it displays correctly and calls
window.Telegram.WebApp.sendData(...). - Popup messages (
alert) appear on the screen confirming that the page is trying to send data. - However, in the bot's logs (on the Python side), no updates of type
web_app_dataappear. That is, theweb_app_data_handleris not called at all. - As a result, the bot "hangs" at the date and time selection step and does not proceed to the next question ("Number of guests").
Checked Steps:
- In
BotFather, I added the domain in the settings:- (I confirm that the
Domainfield containsdanza13.github.iowithouthttps://and without/telegram-webapp/.)
- (I confirm that the
- In the
.envfile, the value ofWEB_APP_URLis set to the full pathhttps://danza13.github.io/telegram-webapp/. - In
index.html, there is a checkif (window.Telegram && window.Telegram.WebApp), the page opens in Telegram, sowindow.Telegram.WebAppexists. - On the frontend,
tg.sendData(...)is called, wheretg = window.Telegram.WebApp. - The bot's logs show that after pressing "Confirm," no new Update is received from Telegram.
What the Problem Is:
It seems that Telegram does not "trust" my domain and does not send any WebApp data, or the domain settings in BotFather are not working correctly. As a result, sendData() leads to nothing (the bot does not receive the event).
Please help to figure out why the data from sendData() does not reach the web_app_data_handler and what else should be checked or configured for the WebApp to fully send data to the bot.
