In a traditional Web application, the backend service should never trust the payload sent from the user frontend. Though the frontend pages use carefully designed UI to force users to send data in a valid/expected format, they can’t prevent advanced users from directly calling API endpoints and sending invalid/malicious data. So backend service should always validate the data.

I need to determine whether messages in the bot channel are original or replies to previous messages. To achieve this, I plan to save the results in a JSON file. First, I need to detect if a message is an original message or a reply. I understand that replies to older messages will have the reply_to_message attribute. Could you advise on how to detect this?

I have been using https://api.telegram.org/bot${TELEGRAM_BOT_TOKEN}/getUpdates in my code for a few days and when randomly testing today i found many previous entries were missing which were there previously. So, is there any limit to how many results it can show after removing them and showing new ones and if yes how do i get all entries?

I’m developing a Telegram mini app and facing a challenge. I need the app to let users return to the bot, send a video, and then reopen the mini app without reloading it. I tried using openTelegramLink, but it doesn’t work with the bot that opened the mini app. Does anyone know how to achieve this or have any alternative solutions?

Bots are limited in permissions to personal accounts in Telegram (e.g. bot can be added to a group by admin only but any personal account can be added to the group freely). So bot API is not suitable.
Is there a way to automate personal account in Telegram?
