Class RESTResponseMgr
![](https://sfcclearning.com/infocenter/DWAPI/scriptapi/html/api/images/inherit.gif.pagespeed.ce.4vPrGmNumQ.gif)
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 Detail
createEmptySuccess
Constructs a new RESTSuccessResponse 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 object.
Throws:
IllegalArgumentException
-
If the statusCode is not in the (100..299) range.
createError
Constructs a new RESTErrorResponse 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 object.
Throws:
IllegalArgumentException
-
If the statusCode is not in the (400..599) range.
createError
Constructs a new RESTErrorResponse 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:
- If the provided type is not an absolute URL, it will be prepended with
https://api.commercecloud.salesforce.com/documentation/error/v1/custom-errors/
. - Custom error types are not allowed to have SYSTEM error type prefix:
https://api.commercecloud.salesforce.com/documentation/error/v1/errors/
.
Returns:
A new RESTErrorResponse 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
Constructs a new RESTErrorResponse 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:
- If the provided type is not an absolute URL, it will be prepended with
https://api.commercecloud.salesforce.com/documentation/error/v1/custom-errors/
. - Custom error types are not allowed to have SYSTEM error type prefix:
https://api.commercecloud.salesforce.com/documentation/error/v1/errors/
.
title
-
Human-readable summary of the error type.
Returns:
A new RESTErrorResponse 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 SYSTEM error type namespace.
createError
static createError(statusCode
:
Number, type
:
String, title
:
String, detail
:
String)
:
RESTErrorResponse
Constructs a new RESTErrorResponse object. This method can be used to construct error responses with
valid 'statusCode', 'type', 'title' and 'detail'. If you want to omit title or detail, you can pass in
null
.
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:
- If the provided type is not an absolute URL, it will be prepended with
https://api.commercecloud.salesforce.com/documentation/error/v1/custom-errors/
. - Custom error types are not allowed to have SYSTEM error type prefix:
https://api.commercecloud.salesforce.com/documentation/error/v1/errors/
.
title
-
Human-readable summary of the error type.
detail
-
Human-readable explanation of the specific occurrence of the error.
Returns:
A new RESTErrorResponse 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 SYSTEM error type namespace.
createScapiRemoteInclude
static createScapiRemoteInclude(apiFamily

String, resourcePath
:
String, params
:
URLParameter...)
:
RemoteInclude
Constructs a new RemoteInclude object specific for the SCAPI include path.
Usage:

BASE_PATH/product/shopper-products/v1/organizations/ORG_ID/categories/root?siteId=YourShopHereRemoteInclude object can be constructed in a script like following:
let include = dw.system.RESTResponseMgr.createScapiRemoteInclude("product", "shopper-products", "v1", "categories/root", dw.web.URLParameter("siteId", "YourShopHere"));Please notice that 'BASE_PATH' and 'ORG_ID' are automatically resolved.
