With Content API, it was possible to set up API authentication using Merchant
Center. While we have removed this capability, your existing keys remain valid.
You can continue to use them.

## Important things to know

- You need not take any immediate action.
- Your access to the API continues.
- To enable Merchant API for a Google Cloud project, you must have
  a role with permission to enable services on the project, such as Owner
  (`roles/owner`), Editor (`roles/editor`), or Service Usage Admin
  (`roles/serviceusage.serviceUsageAdmin`). If you have the necessary
  permissions, do the following:

  1. Visit the [Google Cloud Console](https://console.cloud.google.com).
  2. Select the relevant Google Cloud project. If you don't find the project, you don't have access. You can recover access or create another Google Cloud project. For instructions on your options, see [Manage and transition Google Cloud projects](https://developers.google.com/merchant/api/guides/accounts/manage-transition-gcp-projects) and [Authorize access to your account](https://developers.google.com/merchant/api/guides/authorization/access-your-account).
  3. If you have access, in the search bar, type "Merchant API".
  4. In the resulting list, select **Merchant API**.
  5. On the **Product details** screen for Merchant API, select **Enable**.
  6. You should see a screen that resembles the following.
