Deno 2.4 Brings Back deno bundle, Improves Dependency Management and Observability
Deno 2.4 brings back bundling, improves dependency updates and telemetry, and makes the runtime more practical for real-world JavaScript projects.
A Python library that provides tools for using and validating Telegram web app init data.
A Python library that provides tools for using and validating Telegram web app init data.
You can install the library using pip:
pip install init-data-py
To parse the window.Telegram.WebApp.initData
query string into an InitData
object for easier access to attributes and validation, you can use the InitData.parse
method:
from init_data_py import InitData
init_data = InitData.parse(query_string)
To validate the init data, you can use the InitData.validate
method:
is_valid = init_data.validate(bot_token)
If you need to create and sign your own init data, you can create an InitData
object and sign it:
from init_data_py import InitData
from init_data_py.types import User
user = User(id=5167898484, first_name="xin")
init_data = InitData(user=user).sign(bot_token)
After creating and signing init data, you can convert it to a query sting using the InitData.to_query_string
method:
query_string = init_date.to_query_string()
This example demonstrates how to validate a Telegram Mini App init data. It parses the init data query string into an InitData
object and validate it using the provided bot token, checking that the data is valid and has not expired:
from init_data_py import InitData
bot_token = "7244657541:AAEgqk0HDC3WD5cdbnGMdd6L0TJ74FDp97Y"
query_string = "query_id=AAF03wc0AgAAAHTfBzROOCVW&user=%7B%22id%22%3A5167898484%2C%22first_name%22%3A%22xin%22%2C%22last_name%22%3A%22%22%2C%22username%22%3A%22pvnimaxin%22%2C%22language_code%22%3A%22en%22%2C%22allows_write_to_pm%22%3Atrue%7D&auth_date=1722938610&hash=8654c8c617c143abf656f4f159be2539880a56f58c2d9be622f90c0346aa162b"
init_data = InitData.parse(query_string)
is_valid = init_data.validate(
bot_token=bot_token,
lifetime=3600,
)
