File

Makes a bot send a file message.

A file can be sent by using a URL or a file ID.

  • Using a URL: Only HTTPS is allowed, and originalContentUrl is required.
  • Using a file ID: The file ID returned when the content is uploaded is used to send messages.

Note about using a file ID

  • Whenever a file message is sent, the recipient's shared storage will be reduced by the size of the file.
  • The following file extensions are blocked by default.
 'bat', 'cmd', 'com', 'cpl', 'exe', 'scr', 'js', 'vbs', 'wsf', 'hta'
  • You can add or remove file extensions to block by default under Security > File Security in the LINE WORKS Admin.
