type HTTPMessage struct {
	To                    string              `json:"to,omitempty"`                      // This parameter specifies the recipient of a message.
	RegistrationIds       []string            `json:"registration_ids,omitempty"`        // This parameter specifies the recipient of a multicast message, a message sent to more than one registration token.
	Condition             string              `json:"condition,omitempty"`               // This parameter specifies a logical expression of conditions that determine the message target.
	NotificationKey       string              `json:"notification_key,omitempty"`        // This parameter is deprecated. Instead, use to to specify message recipients.
	CollapseKey           string              `json:"collapse_key,omitempty"`            // This parameter identifies a group of messages (e.g., with collapse_key: "Updates Available") that can be collapsed, so that only the last message gets sent when delivery can be resumed. This is intended to avoid sending too many of the same messages when the device comes back online or becomes active.
	Priority              string              `json:"priority,omitempty"`                // Sets the priority of the message. Valid values are "normal" and "high." On iOS, these correspond to APNs priorities 5 and 10.
	ContentAvailable      bool                `json:"content_available,omitempty"`       // On iOS, use this field to represent content-available in the APNs payload. When a notification or message is sent and this is set to true, an inactive client app is awoken, and the message is sent through APNs as a silent notification and not through the FCM connection server. Note that silent notifications in APNs are not guaranteed to be delivered, and can depend on factors such as the user turning on Low Power Mode, force quitting the app, etc. On Android, data messages wake the app by default. On Chrome, currently not supported.
	MutableContent        bool                `json:"mutable_content,omitempty"`         // Currently for iOS 10+ devices only. On iOS, use this field to represent mutable-content in the APNs payload. When a notification is sent and this is set to true, the content of the notification can be modified before it is displayed, using a Notification Service app extension.
	DelayWhileIdle        bool                `json:"delay_while_idle,omitempty"`        // This parameter is deprecated.
	TimeToLive            int                 `json:"time_to_live,omitempty"`            // This parameter specifies how long (in seconds) the message should be kept in FCM storage if the device is offline. The maximum time to live supported is 4 weeks, and the default value is 4 weeks.
	RestrictedPackageName string              `json:"restricted_package_name,omitempty"` // This parameter specifies the package name of the application where the registration tokens must match in order to receive the message.
	DryRun                bool                `json:"dry_run,omitempty"`                 // This parameter, when set to true, allows developers to test a request without actually sending a message.
	Data                  interface{}         `json:"data,omitempty"`                    // This parameter specifies the custom key-value pairs of the message's payload.
	Notification          NotificationPayload `json:"notification,omitempty"`            // This parameter specifies the predefined, user-visible key-value pairs of the notification payload.
