Azure Quantum preview API life cycle

The Azure Quantum service preview APIs (APIs that end in -preview) have a lifespan of approximately 90 days after a new preview API version is released. For example, the 2026-01-15-preview Data Plane API will be deprecated about 90 days after the next Date Plane API is released.

After an API version is deprecated, that version no longer functions. To avoid issues with deprecated APIs, routinely do the following:

  • Update your ARM/BICEP templates that use preview API versions to use the latest version of the preview API.
  • Update your Azure Quantum preview CLI extension to the latest version.
  • Update preview SDKs or other tools that are built on preview APIs to the latest version of the preview API.

Perform these updates at least every 6-9 months. If you don't update your preview API versions, then you receive a notification that you're using a soon-to-be deprecated version as the deprecation date approaches.

How to check what preview API versions you're using

If you're unsure what client or tool is using a specific API version, then check the activity logs using the following commands. Set the API version that you want to inspect for recent usage in the activity log. These examples checks for the 2024-10-01-preview API version.

Bash

export API_VERSION="2024-10-01-preview"
az monitor activity-log list --offset 30d --max-events 10000 --namespace microsoft.quantum --query "[?eventName.value == 'EndRequest' && contains(not_null(httpRequest.uri,''), '$API_VERSION')]"

Windows PowerShell

$env:API_VERSION = "2024-10-01-preview"
az monitor activity-log list --offset 30d --max-events 10000 --namespace microsoft.quantum --query "[?eventName.value == 'EndRequest' && contains(not_null(httpRequest.uri,''), '$API_VERSION')]"
