# Class RESTResponseMgr

- [TopLevel.Object](/docs/commerce/b2c-commerce/references/b2c-script-api/TopLevel.Object.md)
  - [dw.system.RESTResponseMgr](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.system.RESTResponseMgr.md)

This class provides helper methods for creating REST error and success responses. It is mainly intended to be used to
build Custom REST APIs. But, any controller implementation planning to provide REST-like responses can use these
methods. If these methods are being used in the controllers, note that a few defaults like URL prefix for
`type` in `createError` methods will correspond to Custom REST APIs.

## Method Details

### createEmptySuccess(Number)

- static createEmptySuccess(statusCode: [Number](/docs/commerce/b2c-commerce/references/b2c-script-api/TopLevel.Number.md)): [RESTSuccessResponse](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.system.RESTSuccessResponse.md)
  - : Constructs a new [RESTSuccessResponse](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.system.RESTSuccessResponse.md) object. This method is to be used in scenarios where response body
    is not expected (e.g. statusCode is 204).

    **Parameters:**

    - statusCode - The http status code of the response. The statusCode parameter should conform to RFC standards             for a success.

    **Returns:**

    - A new [RESTSuccessResponse](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.system.RESTSuccessResponse.md) object.

    **Throws:**

    - IllegalArgumentException - If the statusCode is not in the (100..299) range.

***

### createError(Number)

- static createError(statusCode: [Number](/docs/commerce/b2c-commerce/references/b2c-script-api/TopLevel.Number.md)): [RESTErrorResponse](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.system.RESTErrorResponse.md)
  - : Constructs a new [RESTErrorResponse](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.system.RESTErrorResponse.md) object. This method should be used when you have just the statusCode
    of the error and want the type of error to be inferred.

    'type' of the error is inferred from the status code as follows:

    - `400`- `bad-request`
    - `401`- `unauthorized`
    - `403`- `forbidden`
    - `404`- `resource-not-found`
    - `409`- `conflict`
    - `412`- `precondition-failed`
    - `429`- `too-many-requests`
    - `500`- `internal-server-error`
    - `default`- `about:blank`

    **Parameters:**

    - statusCode - The error code of the response. The statusCode parameter should conform to RFC standards for an             error.

    **Returns:**

    - A new [RESTErrorResponse](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.system.RESTErrorResponse.md) object.

    **Throws:**

    - IllegalArgumentException - If the statusCode is not in the (400..599) range.

***

### createError(Number, String)

- static createError(statusCode: [Number](/docs/commerce/b2c-commerce/references/b2c-script-api/TopLevel.Number.md), type: [String](/docs/commerce/b2c-commerce/references/b2c-script-api/TopLevel.String.md)): [RESTErrorResponse](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.system.RESTErrorResponse.md)
  - : Constructs a new [RESTErrorResponse](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.system.RESTErrorResponse.md) object. This method should be used when you want to omit 'title' and
    'detail' of the error. With this method, custom error codes and types apart from the standard ones can be
    constructed.

    **Parameters:**

    - statusCode - The error code of the response. The statusCode parameter should conform to RFC standards for an             error.
    - type - Type of the error according to RFC 9457. We enforce the following restrictions on top of the RFC:                          <li>If the provided type is not an absolute URL, it will be prepended with             `https://api.commercecloud.salesforce.com/documentation/error/v1/custom-errors/`.</li>             <li>Custom error types are not allowed to have SYSTEM error type prefix:             `https://api.commercecloud.salesforce.com/documentation/error/v1/errors/`.</li>             </ul>

    **Returns:**

    - A new [RESTErrorResponse](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.system.RESTErrorResponse.md) object.

    **Throws:**

    - IllegalArgumentException - If the statusCode is not in the (400..599) range or if the error type is not a              valid URI or conflicts with the SYSTEM error type namespace.

***

### createError(Number, String, String)

- static createError(statusCode: [Number](/docs/commerce/b2c-commerce/references/b2c-script-api/TopLevel.Number.md), type: [String](/docs/commerce/b2c-commerce/references/b2c-script-api/TopLevel.String.md), title: [String](/docs/commerce/b2c-commerce/references/b2c-script-api/TopLevel.String.md)): [RESTErrorResponse](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.system.RESTErrorResponse.md)
  - : Constructs a new [RESTErrorResponse](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.system.RESTErrorResponse.md) object. This method should be used when you want to omit 'detail' of
    the error but want to have valid 'statusCode', 'type' and 'title'.

    **Parameters:**

    - statusCode - The error code of the response. The statusCode parameter should conform to RFC standards for an             error.
    - type - Type of the error according to RFC 9457. We enforce the following restrictions on top of the RFC:                          <li>If the provided type is not an absolute URL, it will be prepended with             `https://api.commercecloud.salesforce.com/documentation/error/v1/custom-errors/`.</li>             <li>Custom error types are not allowed to have SYSTEM error type prefix:             `https://api.commercecloud.salesforce.com/documentation/error/v1/errors/`.</li>             </ul>
    - title - Human-readable summary of the error type.
