current go sdk Subscription struct def:

// Subscription has the same definition as https://github.com/casdoor/casdoor/blob/master/object/subscription.go#L24
type Subscription struct {
	Owner       string `xorm:"varchar(100) notnull pk" json:"owner"`
	Name        string `xorm:"varchar(100) notnull pk" json:"name"`
	CreatedTime string `xorm:"varchar(100)" json:"createdTime"`
	DisplayName string `xorm:"varchar(100)" json:"displayName"`

	StartDate   time.Time `json:"startDate"`
	EndDate     time.Time `json:"endDate"`
	Duration    int       `json:"duration"`
	Description string    `xorm:"varchar(100)" json:"description"`

	User string `xorm:"mediumtext" json:"user"`
	Plan string `xorm:"varchar(100)" json:"plan"`

}

while Casdoor has newer def:

type SubscriptionState string

const (
	SubStatePending   SubscriptionState = "Pending"
	SubStateError     SubscriptionState = "Error"
	SubStateSuspended SubscriptionState = "Suspended" // suspended by the admin

	SubStateActive   SubscriptionState = "Active"
	SubStateUpcoming SubscriptionState = "Upcoming"
	SubStateExpired  SubscriptionState = "Expired"
)

type Subscription struct {
	Owner       string `xorm:"varchar(100) notnull pk" json:"owner"`
	Name        string `xorm:"varchar(100) notnull pk" json:"name"`
	DisplayName string `xorm:"varchar(100)" json:"displayName"`
	CreatedTime string `xorm:"varchar(100)" json:"createdTime"`
	Description string `xorm:"varchar(100)" json:"description"`

	User    string `xorm:"varchar(100)" json:"user"`
	Pricing string `xorm:"varchar(100)" json:"pricing"`
	Plan    string `xorm:"varchar(100)" json:"plan"`
	Payment string `xorm:"varchar(100)" json:"payment"`

	StartTime time.Time         `json:"startTime"`
