# ARCore 1.33 Cloud Anchor endpoint changes

As of the August 2022 1.33.0 release, the
**[ARCore Cloud Anchor API](https://console.cloud.google.com/apis/library/arcorecloudanchor.googleapis.com)**
endpoint is deprecated. All apps built with ARCore SDK 1.33.0 and higher now target the
new
**[ARCore API](https://console.cloud.google.com/apis/library/arcore)**,
general-purpose API intended for use with all ARCore cloud services. All apps
built with ARCore SDK 1.32.0 and lower will continue to target the older API.

This change will not affect existing data. Once an app is updated to use ARCore
SDK 1.33.0 or later, and the new **ARCore API** has been enabled in the Google
Cloud project used by your app, functionality should remain the same as it did
when using the previous end point. To support older app versions, you may enable
both APIs while making the transition.

If your app uses the Cloud Anchors API, you must update it to use ARCore SDK
1.33.0 or later **before August 31, 2023**. After this date, apps compiled with
ARCore SDK 1.32.0 or earlier will no longer be able to host and resolve Cloud
Anchors.

## Naming changes

<br />

|   | Previous | New |
| API name | ARCore Cloud Anchor API | ARCore API |
| Domain name | `arcorecloudanchor.googleapis.com` | `arcore.googleapis.com` |
|---|---|---|

## Update your app to use the new endpoint

To update your app:

1. Visit the [Google Cloud Platform console](https://console.cloud.google.com/).
2. Determine which cloud project your app uses.
3. Ensure that the **ARCore API** is enabled.
4. Update your app to use the latest ARCore SDK. ARCore SDK 1.33 and later use the new ARCore API.
5. Test these changes by using Cloud Anchor API functionality in your app.
6. Verify that the Cloud Anchor API usage for the updated app appears under the **ARCore API** in the Google Cloud project, and *not* under the **ARCore
   Cloud Anchor API**.

## Update app settings

- If your iOS app is using signed JWTs for authorization, change the `audience` claim to `https://arcore.googleapis.com/` for apps built with ARCore SDK 1.33.0 and higher.
- If your API key is [restricted](https://cloud.google.com/api-keys/docs/add-restrictions-api-keys), you must allow the ARCore API.
- If you send requests to the ARCore Cloud Anchor Management API from your backend, you must enable the ARCore API and change the domain name to `arcore.googleapis.com`.
