Notification Channels

A Notification is a Request object without an id member. A Request object that is a Notification signifies the Client's lack of interest in the corresponding Response object, and as such no Response object needs to be returned to the client. The Server must not reply to a Notification, including those that are within a batch request.

Notifications are not confirmable by definition, since they do not have a Response object to be returned. As such, the Client would not be aware of any errors (like e.g. "Invalid params", "Internal error").

Key Note: DRFQ, GRFQ, VRFQ, and the FSPD are separate products with separate JSON-RPCoverWebSocket connection URLs & subscriptions required. You must subscribe to the specific channels of each product you would like to receive notifications for.
