# Request Syntax

## Form Fields in Request Bodies

All request bodies should be sent as a `multipart/form-data` content type. Depending on the kind of operation to perform, a request body can contain the following form fields:

* [data](#data-form-field)
* [file](#file-form-field)

### `data` form field

Attributes can be added to an entity by specifying them as key-value pairs in a JSON string and adding them to your request in the form-data field `data`.

This JSON string has the following format:

```json
{
  "attributes": {
    "name": "Welcome to IDP.docx",
    "createdBy": "User"
  }
}
```

### `file` form field

When uploading files, the file(s) should be contained in a form-data field named `file`.
