We see that the Spectrum REST API for deleting subscriptions always returns a 200 (success) response code, even if an non-existent subscription ID is specified. This makes it impossible to know if the deletion really succeeded. For example, if you accidentally provide a wrong subscription ID, your mistake will not flagged.
We expect that if an non-existent subscription ID is specified, the API should return an error code.
