Introduction

You can use the orchestration workflow service step to access and configure the RESTCaller service to call REST Web services.

XML data from the orchestration workflow can be mapped into the RESTCaller and sent to the REST Web service as text, XML, or as JSON data. Similarly, XML data returned by the REST Web service can be mapped into the orchestration workflow. If the REST Web service returns JSON data, it can be translated to XML and mapped into the orchestration workflow as XML.

Note: If you are modifying process apps created in a prior version of SBM, you must do one of the following to refresh the process app with the latest RESTCaller functionality:

If you are using a process app that was created prior to 10.1.5 (or if you delete the service from your process app):
- From the context menu, right-click the Web Services node, select Add, and then select RESTCaller.
- From the context menu, right-click the Web Services node, select Add New Web Service, and then manually import the RESTCaller.wsdl into your orchestration. The RESTCaller.wsdl can be found here:
```
http://ServerName:Port/orchestrationutilities/services/RESTCaller?wsdl
```
If you have an existing process app created in SBM version 10.1.5 or higher, you can get the latest features by viewing the property pane of the RESTCaller service in your Orchestration and clicking the WSDL Refresh button. Features added since 10.1.5 are upward compatible and refreshing the .wsdl is only necessary if you need the new features.

RESTCaller is a system service that uses Security Token authentication by default. If you import RESTCaller, you must ensure that it uses Security Token authentication by performing the following steps:

Log in to SBM Application Repository.
Open the Environments view and select your environment.
Edit the RESTCaller service endpoint and set the authentication to Security Token.
Redeploy the process app to the environment.
