About Rest API Patch call

I am converting test executions from Powershell to Katalon.
But, katalon does not support Rest API PATCH call.

Is there a way to execute powershell call, like this one:
$global:response = Invoke-WebRequest -Method Patch -Uri $SiteURL -Headers $Header -ContentType “application/json; charset=utf-8” -Body $Body

And then proceed with values from $global:response, which is in json format?

Hello,
if nobody will offer more “Katalon” solution, there is allways way to do it in groovy.:

We have found this solution:
https://communities.ca.com/thread/241759991-rest-call-with-method-patch

Works quite well for us.

Hi Dejan, could you please provide some more detail on how you implemented this in Katalon? Did you place the code inside of a custom keyword?

Heres my solution. I’ve implemented it as a Keyword which you pass the URL, Identifier (In my case a guid) and the json string you are attempting to PATCH. It then returns the API response as an object which can be tested against. Still really confused as to why PATCHing is not supported in Katalon:

package customMethods

public class HTTPRequest {

def PATCH(String URL, String Identifier, String JSONBody) {

OkHttpClient client = new OkHttpClient()
MediaType mediaType = MediaType.parse("application/json")
String url = URL + '/' + Identifier
String requestBody = JSONBody
RequestBody body = RequestBody.create(mediaType, requestBody)
Request request = new Request.Builder()
.url(url)
.patch(body)
.addHeader("content-type", "application/json")
.addHeader("cache-control", "no-cache")
.build();
Response response = client.newCall(request).execute()
String responseBodyString = response.body().string()
//Create a new jsonSlurper object to manipulate the response from the API
JsonSlurper jsonSlurper = new JsonSlurper()
//Create a new object which will represent the response data from the API
def responseObject = jsonSlurper.parseText(responseBodyString)
return responseObject
}
}

I try to use your script in katalon 5.7.1 and I can import

import okhttp3.MediaType
import okhttp3.OkHttpClient
import okhttp3.Request
import okhttp3.RequestBody
import okhttp3.Response

any idea what is happened , How can import thats libraries

I followed this guide: https://communities.ca.com/thread/241759991-rest-call-with-method-patch

Make sure you get the same versions stated in the guide otherwise it wont work. If you then import them into your project by going to Project / Settings / External Libraries, you should be good to go!

Hopefully we wont need to do this for to long as PATCH is coming to Katalon!: http://forum.katalon.com/discussion/comment/22811#Comment_22811
