  "summary": "This article provides a step-by-step guide for implementing a backend validation mechanism in PHP, specifically for a Yii2 application, that verifies authentication payloads received from the official Telegram Login Widget. The process involves constructing a data_check_string, generating a secret key using the SHA-256 hash of the bot token, and validating the payload signatures using the hash_equals() function. The guide also explains how to bind verified telegram_id records in Yii2 and covers important aspects such as payload freshness verification and key derivation.",
