## Announcement Released 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). ## 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.
