You can find implementation of org.wso2.carbon.bpmn.extensions.rest.RESTTask class here
https://github.com/wso2/carbon-business-process/blob/master/components/bpmn/org.wso2.carbon.bpmn/src/main/java/org/wso2/carbon/bpmn/extensions/rest/RESTTask.java

Currently it supports GET and POST only. If you need support for other HTTP methods you have to implement custom java service task similar to REST Task implementation that supports rest of REST API functionalities.
