TELEGRAM WEB APP
Task:
Develop a server function in PHP for validating the hash of data transmitted from the Telegram Web App.
Description:
Client side:
User data initialization is performed through window.Telegram.WebApp.initData.
After that, user data is sent to the server via an HTTP request using Axios.
Instead of initData, initDataUnsafe or initDataRaw can be used, but in this case, it will be necessary to send the client code that works with these methods.
Server side:
Implement a function to process incoming data, including:
Generating a hash from the transmitted data using the algorithm specified in the Telegram Web App documentation.
Comparing it with the hash received on the client (for example, from initData).
Ensuring that the generated hash matches the original one received from Telegram.
Implementation requirements:
The code must work correctly in testing conditions, including:
Handling any valid input data.
Generating the hash strictly according to the Telegram algorithm.
In case of errors or discrepancies, provide handling (for example, displaying an error message).
Use PHP.
Results:
Working server code for hash validation.
If the initDataUnsafe or initDataRaw method is used, provide client code for testing.
Success criteria:
Complete match of the hash generated by the server with the hash from initData.
No errors during the validation process.
