### License Authorization Method

There are two types of product licenses based on how the client application authorizes itself to interact with a license:

* Key-based product licenses: client interactions with the license have to be authorized using a `license_key`
* User-based product licenses: the license has a corresponding "license user" instead of a license key. Client interactions with the license have to be authorized using a `username`

### Errors

If an error occurs, the response will have an HTTP status code of 400 or higher, and the response body will contain an error description in the following format:
