Alpha update release of API Gateway Released an updated version of the Alpha version of API Gateway

## Announcement Alpha update release of API Gateway Released an updated version of the Alpha version of API Gateway. To provide feedback or to log issues with this release, see [Getting support](https://cloud.google.com/api-gateway/docs/getting-support). ## Feature You can now use the Google Cloud Console UI, a web-based, graphical user interface, to develop your APIs. See the [Quickstart: Use the UI to deploy an API on API Gateway](https://cloud.google.com/api-gateway/docs/quickstart-console) for more. ## Feature The [gcloud command-line tool](http://cloud.google.com/sdk/gcloud) now supports new command options, including: * Create, list, update, and delete APIs. That means you no longer have to use [Cloud Endpoints](https://cloud.google.com/endpoints/docs) commands to work with an API. See [Creating an API](https://cloud.google.com/api-gateway/docs/creating-api) for more. * Update an API config to modify its labels or display name. See [Updating an API config](https://cloud.google.com/api-gateway/docs/creating-api-config#updating-an-api-config) for more. ## Feature Updated the [REST API reference](https://cloud.google.com/api-gateway/docs/reference/rest) to the latest Alpha version. ## Fix Previously, when the `gcloud` command failed while creating an API config, the API config was still created, requiring you to manually delete it. The `gcloud` command no longer requires you to delete the API config when the create command fails. ## Issue When creating a gateway, permissions can take more than a minute to propagate through the system. Therefore, you might see a "missing tokens" error when making a request to an API. If you see this error, wait several minutes, then retry the request. ## Issue Authentication is only supported for Cloud Run and Cloud Functions, not for App Engine.
