Header Fields

Name	Description
`X-SBG-Auth-Token` required	Your CAVATICA authentication token.
`Content-Type` required	`application/json`

Query parameters

Name	Datatype	Description
`overwrite`	Boolean: `true` or `false`	If `overwrite` is set to `true` and a file already exists under the name specified in the request, the existing file will be deleted and a new one created in its place.

Request body

In the body, you should enter a list of key-value pairs. The keys, and the values they take, are described in the following table.

Key	Datatype of value	Description of value
`project` Required	String	The name of the project you want to upload a file to.
`parent`	String	The ID of the folder to which the item is being uploaded. Should not be used together with `project`. If `parent` is used, the upload will take place into the specified folder, within the project to which the folder belongs. If `project` is used, the items will be imported to the root of the project's files.
`name` Required	String	The name of the file you are about to upload. This must be unique in the project, unless you are also enabling the `overwrite` query parameter. Allowed characters in file names are all alphanumerics and special characters except slash (`/`). File names can’t be longer than 255 characters.
`size`	Integer	The size of the file that will be uploaded. This can be used to track progress of an ongoing upload, but is otherwise optional.
`part_size`	Integer	The preferred size for upload parts. If omitted or set to a value that is incompatible with the cloud storage provider, a default value will be used.
`md5`	String	32-byte hexadecimal MD5 checksum of the file. This value is currently only stored but is not used by the Platform.
