# POST /v1/appStoreVersionExperiments is deprecated

App Store Connect API deprecated POST /v1/appStoreVersionExperiments without giving a shutdown date yet.

App Store Connect API deprecated the POST /v1/appStoreVersionExperiments endpoint without a shutdown date. Calls made to this route will eventually fail as it has been marked as deprecated. The change affects any integration creating app store experiments using the v1 endpoint.
