Workflows

discover-available-target
List provider statuses and surface targets from an available provider.
Calls Providers_List for the workspace and inspects the first returned provider's currentAvailability. When the provider is Available the workflow returns its id and targets array; otherwise it surfaces the unavailable status so the caller can choose differently.
3 steps inputs: apiVersion, authToken, resourceGroupName, subscriptionId, workspaceName outputs: firstTargetId, selectedProviderId, selectedTargets, unavailableProviderId
1
listProviders
Providers_List
List the status of all providers in the workspace, returning their current availability and per-target statuses.
2
reportAvailable
Providers_List
The first provider is available; re-read provider status to confirm and surface its id and target list for target selection.
3
reportUnavailable
Providers_List
The first provider is not available; surface its id and availability so the caller can pick another provider or retry later.

  title: Azure Quantum Discover an Available Target
  summary: List provider statuses in a workspace and branch on availability before selecting a target.
  description: >-
    Before submitting work, a client needs to know which providers and targets
    are currently available in a workspace. This workflow lists provider status
    with Providers_List, branches on the first provider's current availability,
    and on an available provider returns its id and the list of target statuses
    so a caller can pick a target to run against. Each step spells out its
    request inline, including the inline Authorization bearer token and the
    required api-version query parameter.
