# sObject Blob Get

Gets the specified blob field from an individual record and returns it as binary data. Only certain standard objects have blob fields, such as Attachment, ContentNote, ContentVersion, Document, Folder, and Note.

:::note
The sObject Blob Get resource isn’t compatible with Composite API requests, because it returns binary data instead of data in JSON or XML formats. Instead, make individual sObject Blob Get requests to retrieve blob data.
