```
@Immutable() 
public final class Attachment
 implements CustomObject
                    
```
Represents an attachment. Most commonly these are files, images, videos and audio recordings, but the class is flexible enough that it can represent other things as well such as a date, a given location or other things.
If you want to create a custom attachment we suggest you use extraData to store the information you need.
