Document

This object represents a general file (as opposed to photos, voice messages and audio files).

Properties

  • file_id (str): Identifier for this file, which can be used to download or reuse the file
  • file_unique_id (str): Unique identifier for this file, which is supposed to be the same over time and for different bots. Can't be used to download or reuse the file.
  • thumbnail (PhotoSize): Optional. Document thumbnail as defined by sender
  • file_name (str): Optional. Original filename as defined by sender
  • mime_type (str): Optional. MIME type of the file as defined by sender
  • file_size (int): Optional. File size in bytes. It can be bigger than 2^31 and some programming languages may have difficulty/silent defects in interpreting it. But it has at most 52 significant bits, so a signed 64-bit integer or double-precision float type are safe for storing this value.
