Get a generated device authorization code.
This is the first step in the process of authorizing a device by pin code. The device will make a request to this endpoint providing a unique identifier for the device such as a serial number. This endpoint will then return a generated code which is tied to the given device.
The code may subsequently be used to authorize the device to sign in to an
account via the /account/devices/authorization endpoint. Typically this
will be from a page presented in the web app under the account section.
Once authorized, the device will then be able to sign in to that account
via the /authorization/device endpoint, without needing to provide the
credentials of the user.
