1. Use a `blob` parameter to set blob fields

curl -X PUT \
-H "Content-Type: application/json" \
-H "QB-Token: f8dd521e8a88b0df7e0c359dc3de73fc15012bba" \
-d '{  
  "blob":{  
  }
}' \

2. Update a file content to new

Set a new to 1 in the blob to update the file content.
curl -X PUT \
-H "Content-Type: application/json" \
-H "QB-Token: f8dd521e8a88b0df7e0c359dc3de73fc15012bba" \
-d '{  
  "blob":{
    "new":"1"  
  }
}' \

3. As a result, the file is replaced with a new one.

  }
}' \

3. As a result, the API returns a file with an updated name.

{
  "blob": {
    "id": 9715867,
    "uid": "9dc0d37c9be34c839ae3bcac4bbaace100",
    "content_type": "image/jpeg",
    "name": "apple",
    "size": 16766,
    "created_at": "2019-09-15T19:40:18Z",
    "updated_at": "2019-09-15T20:35:45Z",
    "blob_status": "complete",
    "set_completed_at": "2019-09-15T20:00:46Z",
    "public": false
  }
}
Update a file name, content type or file tag list. You can also update the file content by setting new=1 parameter. Once set, the file is deleted in the cloud storage and a new record is created. Consequently, all file fields, except for the name, are updated in the cloud storage including the uid, size, etc.
