Hi, During runtime I want to replace a local variable with another value. In other words, I want to replace the request variable called ${Id} at runtime. I’ve tried the following code but it fails to use the value 222222, instead it’s still pulling the Id value from the “Variables” tab. Please help. Thanks RequestObject request = WSResponseManager.getInstance().getCurrentRequest() requestBody = request.getSoapBody() requestBody.replace(’${Id}’, “222222”) request.setSoapBody(requestBody) System.out.println("request body = " + request.getSoapBody()) response = WS.sendRequest(request) //Request ``` ${FirstName} ${Id} ``` ---

I have published a GitHub repository > **[GitHub - kazurayam/PetstoreSwaggerIo](https://github.com/kazurayam/PetstoreSwaggerIo)** > > Contribute to kazurayam/PetstoreSwaggerIo development by creating an account on GitHub. This project is a working example, which shows 1. hoow to define a parameterised TestObject 2. Test Case turns a parameterised TestObject to a RequestObject 3. using that RequestObject, Test Case makes multiple times of request&response interaction to ([https://petstore.swagger.io/v2/pet/findByStatus?status=${status}](https://petstore.swagger.io/v2/pet/findByStatus?status=$%7Bstatus%7D)) while interpolating the parameter with values as wanted Please read the source of `Test Cases/multiple_searches_for_pets_by_status` and study it to find out how it works. This example may not be an immediate answer to your problem. But hopefully it will give you some idea. * * * The TestObject looks like this: ![スクリーンショット 2021-02-13

com.kms.katalon.core.testobject.ObjectRepository.findTestObject import com.kms.katalon.core.testobject.RequestObject import com.kms.katalon.core.testobject.ResponseObject import com.kms.katalon.core.testobject.TestObject import com.kms.katalon.core.webservice.keyword.WSBuiltInKeywords as WS def statusList = ["available", "pending", "sold"] for (status in statusList) { println "-------------------- ${status} pets --------------------" String doc = retrievePetsByStatus(status) println doc } def retrievePetsByStatus(String status) { TestObject tObj = findTestObject("Object Repository/my/petstore_findByStatus_parameterized", ["status": status]) RequestObject req = (RequestObject)tObj ResponseObject res = WS.sendRequest(req) return res.getResponseBodyContent() } ``` When I rant it I saw outputs like this: ```auto -------------------- available pets --------------------

@ThanhTo I reviewed the document > **[Parameterize a Web Service Object](https://docs.katalon.com/katalon-studio/docs/parameterize-a-web-service-object.html)** > > Query Parameters Only available for RESTful Web Service requests Query parameters can be added to a REST request's URL to tailor and filter the response output. When you input a URL, Katalon... and found that this document is not enough for @zaraaq9. This document describe how to define a TestObject (=WS RequestObject), and just that. The document does not describe how to use it. Especially it should cover how to make multiple times of request/response interactions with different parameter values. ---

@zaraaq9 why don’t you bind the needed value when calling the webservice from the testcase, instead of re-building the body? @kazurayam the usage of parametrized webservice objects is explained here: > **[Using Web Services in a Test Case](https://docs.katalon.com/katalon-studio/docs/using-web-services-in-a-test-case.html#in-test-case-editors-script-view)** > > Katalon Studio supports various ways to use a Web Service object in a test case. You can call the web service methods from Manual View (keywords test), Script View (test... quote: ```auto def response = WS.sendRequest(findTestObject([the ID of Web Service object], ["variable1": value1, "variable2": value2, ... , "variableN": valueN])) ``` ---

@kazurayam, Running from test is not a problem, I have been doing what you’ve described here. I wanted to learn how to do this from the object repository.
