How to enable users to delete their own Keycloak account using API?

Question

I have an Express.js CRUD application and I use Keycloak 18.0.2 for identity management. Keycloak handles Google and Facebook Single Sign-On (SSO) for my application, and all authentications are managed through Keycloak. Currently, users are authenticated using their access tokens received in HTTP requests.

I want to implement a feature where users can delete their own accounts without requiring administrative privileges. Ideally, I would like to use the user's token received in the HTTP request to authenticate and delete the user record from Keycloak. So user will make request to DELETE base_url_to_my_express_js_application/users then I will delete user from my application and then call the Keycloak deletion API with the same token I received as authorization header.

I have tried the following approaches without success:

1. On internet I got suggestion for Enabling "Self-Service Account Management" in Keycloak's "Account" tab: I found that there is no "Account" tab in Keycloak 18.0.2, and I couldn't locate the option to enable self-service account management.
2. Making a DELETE request to https://my-keycloak/auth/realms/my-realm/account: This endpoint returns status 404.

  {
    "error": "RESTEASY003210: Could not find resource for full path:http://your-keycloak-server/auth/realms/your-realm-name/account
  }

3. Making a DELETE request to https://my-keycloak/realms/my-realm/account: This endpoint returns status 405.

  {
    "error": "RESTEASY003650: No resource method found for DELETE, return 405 with Allow header"
  }

Since the above approaches didn't work as expected, I'm seeking guidance on how to implement this feature using the Keycloak Admin API or any other alternative method. Specifically, I would like to know:

• How can I enable users to delete their own Keycloak accounts using their own access tokens ?
• Is there a specific Keycloak Admin API endpoint that allows users to delete their own accounts? If so, how can I access it?
• If the above approach is not possible, what alternative methods can I use to implement the account deletion feature securely?

I appreciate any insights, examples, or guidance on how to achieve this functionality within the Keycloak 18.0.2 version.

Thank you in advance for your help!

Enabling account deletion by users

End users and applications can delete their accounts in the Account Console if you enable this capability in the Admin Console. Once you enable this capability, you can give that capability to specific users.

Giving a user the delete-account role

You can give specific users a role that allows account deletion.

Procedure Click Users in the menu.
