2.12.17.2 Operation $status on Subscription

FHIR Infrastructure icon Work Group Maturity Level: 2Trial Use Compartments: N/A

This operation is used to return the current status information about one or more topic-based Subscriptions.

The canonical URL for this operation definition is

 http://hl7.org/fhir/OperationDefinition/Subscription-status

Formal Definition (as a OperationDefinition).

URL: [base]/Subscription/$status

URL: [base]/Subscription/[id]/$status

This is an idempotent operation

In Parameters:
Name Scope Cardinality Type Binding Profile Documentation
id type 0..* id

At the Instance level, this parameter is ignored. At the Resource level, one or more FHIR ids to Subscription resources to get status information for. In the absence of any specified ids, the server returns the status for all Subscriptions available to the caller. Multiple values are joined via OR (e.g., "id1" OR "id2").

status type 0..* code Subscription Status (Required)

At the Instance level, this parameter is ignored. At the Resource level, a Subscription status code to filter by (e.g., "active"). In the absence of any specified status values, the server does not filter contents based on the status. Multiple values are joined via OR (e.g., "error" OR "off").

Out Parameters:
Name Scope Cardinality Type Binding Profile Documentation
return 1..1 Bundle

The operation returns a bundle containing zero or more SubscriptionStatus resources, one per Subscription in the request that was found. The Bundle type is "searchset".

Note: as this is the only out parameter, it is a resource, and it has the name 'return', the result of this operation is returned directly as a resource
