Why is the video not being sent by file_id?

Question

PHP

Good afternoon.

The task is to send a Video Note (round video). To do this, there is an API method sendVideoNote

To get the file_id, I send my file to the bot, it returns JSON to me, where in json.message.video.file_id, the required ID lies.

Now I send a request like ' https://api.telegram.org/bot ' .'TOKEN' . '/sendVideoNote' + parameters ['chat_id'=>num,'video_note' => file_id]

But silence in response. Error 400.
Sent both through the server and through Postman. All requests go away, this one doesn't. Moreover, if video_note is specified as a simple link to an mp4 video, it is displayed as a regular video (but I need a round one, so I think it needs to be through file_id)

Where could I be wrong?

Answer 1

Regarding the file_id Telegram, inspected that files are sent only if it was uploaded to this particular chat bot. (That is, you need to send documents / photos / videos to the bot to which you want to send these files later, return the file_id of this dock, and then you can use it)
For some reason, it did not work to load by URL. Writes an incorrect sending format.
