How to retrieve the file_id of an uploaded file in Telegram bot?

In the Telegram API documentation, it states that you can use a file_id to resend a photo that is already on the Telegram servers. However, I couldn’t find any information about obtaining the file_id for an uploaded file. Does anyone know how to get this file_id after uploading a file?

yo, when u upload a file with sendPhoto or sendDocument, the API response has the file_id. just gotta parse it right. if ur using python-telegram-bot, its super easy. after sending, grab the file_id from the response object. like response.photo[-1].file_id for pics. save those ids, theyre permanent and save bandwidth. good luck!

As someone who’s worked extensively with Telegram bots, I can tell you that getting the file_id is actually quite straightforward. When you upload a file using methods like sendPhoto or sendDocument, the API response contains the file_id. You just need to parse this response.

In my experience, using a library like python-telegram-bot makes this process much easier. After sending the file, you can extract the file_id from the returned object. For instance, with photos, it’s usually response.photo[-1].file_id.

One tip: always store these file_ids once you’ve got them. They’re permanent and can save you a lot of bandwidth by allowing you to resend files without re-uploading. Just remember, file_ids are bot-specific, so you can’t use them across different bots.

Hope this helps! Let me know if you need any clarification on the implementation.

I’ve encountered this issue before. When uploading a file with methods such as sendPhoto or sendDocument, the API response includes the file_id, which you can extract by parsing the received JSON. For instance, using the python-telegram-bot library, you can obtain the file_id with response.photo[-1].file_id after sending a photo. Storing these file_ids is beneficial since they are permanent and can prevent the need for future uploads. Note that file_ids are unique to each bot, so they cannot be shared between different bots.
