REST Resource: spaces.messages.attachments

    • An Attachment resource represents a file attached to a Google Chat message, containing metadata such as file name, content type, and source.

    • Attachment includes URLs for thumbnail preview and user download, but Chat apps should utilize the data_ref field for accessing content.

    • The data_ref field can point to either uploaded content within Chat ( AttachmentDataRef ) or a Google Drive file ( DriveDataRef ).

    • AttachmentDataRef is used by Chat apps to create/update messages with attachments or to download attachment data via the media API.

    • Developers can use the get method to retrieve metadata for a specific message attachment.
