This Code system is used in the following value sets:

The type of method used to execute a subscription.

This code system defines the following codes:

rest-hook Rest HookThe channel is executed by making a post to the URI. If a payload is included, the URL is interpreted as the service base, and an update (PUT) is made.
websocket WebsocketThe channel is executed by sending a packet across a web socket connection maintained by the client. The URL identifies the websocket, and the client binds to this URL.
email EmailThe channel is executed by sending an email to the email addressed in the URI (which must be a mailto:).
sms SMSThe channel is executed by sending an SMS message to the phone number identified in the URL (tel:).
message MessageThe channel is executed by sending a message (e.g. a Bundle with a MessageHeader resource etc.) to the application identified in the URI.
