**Use the ACUL rendering configuration object**

The ACUL rendering configuration is a single JSON object that is used to enable ACUL and list all the available properties, per screen, which consist of specific assets, context data, and applicable conditional logic. The ACUL rendering configuration object can be used with IaC tools and the Auth0 Management API.

To learn more, review the [`/v2/prompts/patch-rendering`](https://auth0.com/docs/api/management/v2/prompts/patch-rendering) endpoint.

## Infrastructure-as-Code (IaC)

Configure ACUL with IaC tools, including:

* The **Auth0 CLI's** [`auth0 acul`](https://auth0.github.io/auth0-cli/auth0_acul.html) command.
* The **Auth0 Terraform Provider's** [`auth0_prompt_screen_renderer`](https://registry.terraform.io/providers/auth0/auth0/latest/docs/resources/prompt_screen_renderer) resource.
* The **Auth0 Deploy CLI's** [`prompts`](https://github.com/auth0/auth0-deploy-cli/blob/master/docs/resource-specific-documentation.md#prompts) resource.

## Auth0 Management API

Use ACUL Management API endpoints to configure Universal Login screens individually or to update multiple screens with one API call. You must have [Management API access token](/docs/secure/tokens/access-tokens/management-api-access-tokens) in the request.

**Individual screen configuration**

* The [`GET /v2/prompts/{prompt}/screen/{screen}/rendering` endpoint](/docs/api/management/v2/prompts/get-rendering) allows you to retrieve the configuration for a single screen.

* The [`PATCH /v2/prompts/{prompt}/screen/{screen}/rendering` endpoint](/docs/api/management/v2/prompts/patch-rendering) allows you to configure ACUL on a single screen.

**Bulk screen configuration**

* The [`GET /v2/prompts/rendering` endpoint](/docs/api/management/v2/prompts/get-all-rendering) allows you to retrieve configurations for all the screens.

* The [`PATCH /v2/prompts/rendering` endpoint](/docs/api/management/v2/prompts/patch-bulk-rendering) allows you to update screens in bulk.
