Notice: Over the next few months, we're reorganizing the App Engine documentation site to make it easier to find content and better align with the rest of Google Cloud products. The same content will be available, but the navigation will now match the rest of the Cloud products.

APIs and Reference

Superseded APIs

The APIs in this section are still supported, but are no longer recommended. Instead, use the Cloud client libraries.

Apps that use these superseded APIs will need to migrate to the Cloud client libraries and other services before upgrading to newer Google Cloud runtimes or other environments that support Java.
