The only other way to store a file in HubSpot is to store it in a file property. File properties are actually text fields that can either reference a URL where a file is stored or the ID of a file stored in HubSpot files. Thanks to this, you can actually use the Files API to upload a document and then use the ID returned in the response to update the file property on the object.
