Properties

file_id

file_id: string

Identifier for this file, which can be used to download or reuse the file

Optional file_name

file_name?: string

Optional. Original filename as defined by sender

Optional file_size

file_size?: number

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.

file_unique_id

file_unique_id: string

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.

Optional mime_type

mime_type?: string

Optional. MIME type of the file as defined by sender

Optional thumb

thumb?: IPhotoSize

Optional. Document thumbnail as defined by sender
