Telegram bot webhook returns error 400 for an invalid file ID. For example, try:
<?php file_get_contents("https://api.telegram.org/botX/sendVideo?chat_id=Y&video=Z"); ?>
What might be the issue?
hey, i had a similar prob-lem. check if youre using a valid file id. sometimes the error arises when you mix up file id and url. try using the correct mode and parameters as per telegram docs. hope it helps
In my experience, the error might result not just from mixing up file IDs and URLs but also from the parameter formatting in your API request. I encountered a similar issue where the bot was rejecting the webhook due to unexpected character encoding. Verify that your file ID belongs to a file already uploaded and that your request adheres strictly to Telegram’s API requirements. In addition, test the API call with alternative files to isolate whether the problem lies with the identifier or with the request implementation as a whole.
