REST – PATCH Request 200

18 Jun 2021

This Article covers the HTTP method PATCH, requests made to a REST API to update resources partially (Not Completely) at the URI end, and validate the response through Scriptworks API testing.


In this article, we will perform a PATCH Request on the REST API to show an update operation partially on the resource end (Not Completely) and validate it through Scriptworks - A Visual Programming/low Code Automation tool.

First, I will demonstrate the exercise we need to perform, followed by practically demonstrating the Automation through Drag and Drop of the relevant Blocks present in Scriptworks for achieving it.

HTTP Verb Discussed in this Article:-

PATCH:- HTTP Method PATCH is used to update resources, only those resources where updates are required from the user end, not the entire resource at the URI end. Generally, it is used to create subordinate resources.

Unlike PUT requests, PATCH requests are not idempotent.

Note – Here, We are using to practice on  REST API’s queries response validation.


1) Open your preferred browser chrome, firefox, etc. 

Navigate to any browser

2) Navigate to

open browser

3) Perform Patch Request and validate the response code 200. Although the screenshot is the same as shown in the PUT request, we will change the job role while doing it practically in  Scriptworks for demonstration and understanding purposes.

Practical Demonstration

Following are the Steps to Perform the above Exercise, including validation using Low Code Visual Programming in Scriptworks:-

Pre-requisite: Users should be able to login to Scriptworks via their Credentials, and their Scriptworks Client should be up and running. 

To know more about Scriptworks Client and Selenium Standalone Server, please follow this Article.

1) Open Scriptworks on your system with your credentials and open the project where you want to perform the Automated validations on the REST API response.

open scriptworks with REST_API_Samples_Project

2) Now click on the Block symbol present on the left side panel and then click on getting started

BlockSymbol → Getting Started → API Test

As we know, we are going to initiate an API test. So Drag and Drop the “API Test” block onto the Canvas after clicking on the Getting Started link.

look for getting started link

select api test block

Putting API Test Block into the Canvas

3) Now, we will use the comment block to let others know what we will perform. For that, we are going to click on the search text box and write comment, and hit return.

Search → Comment → Drag and Drop to Canvas

Search for block you need in search box

Put Text in comments Block

4) Now, we will drag and drop some basic blocks required for a REST API request.

For REST API Request, we need four basic things from Scriptworks.

i) REST Call Block

ii) Method Block

iii) URI Block

iv) Response Block

We have searched for the comment block in step 3 similarly we have to do the same for the required blocks and drag and drop them to canvas.

  1. Search → REST Call → Drag and Drop to Canvas
  2. Search → Method → Drag and Drop to Canvas
  3. Search → URI → Drag and Drop to Canvas
  4. Search → Body → Drag and Drop to Canvas
  5. Search → get Response → Drag and Drop to Canvas

Demonstrating Drag and Drop of Rest call Block to Canvas

Search Rest Block from Search Box

Putting Rest Block inside the Canvas

Demonstrating Drag and Drop of Method Block into Canvas

Search Method Block frosearch box present in left side panel

Putting Method Block Inside the Canvas

By default, we would have GET as an HTTP method. Change it to PATCH by clicking the drop-down present in the method block.

Select Patch Method from the Drop Down

Demonstrating Drag and Drop of URI Block into Canvas

Search URI from Search Box present in left hand side panel

In URI Block Enter “

URL needs to enter in URI Block

Demonstrating Drag and Drop of Add Body Block into Canvas

Search Add Body Block from Searchbox present in left hand side panel

Now enter the Payload inside the add body block.


By default Scriptworks provides a single line text edit field which is adequate for entering or editing smaller values. A recently added feature is the multiline block that can be expanded to display and edit much larger values e.g. a request body, as follows:

Click on Block symbol → Click on Input Values Link → Choose Multiline block → Drag and drop to Canvas.

Choose Multiline Block

Putting Multiline Block inside Canvas

Expanded multiline block

Demonstrating Drag and Drop of get response Block into Canvas

Search get Response from Search Box from left hand side panel

putting get response block inside the canvas

5) Let’s give it a dry run and see what we are receiving in the response after the run.

Request Details with Response Headers

In the above screenshot, we can see what request we have sent to the Rest API query with the kind of request headers that have been passed.

Response Details with Response Headers

In the above screenshot, we can see how Scriptworks is logging the REST API response.

6) Drag comment to let others know what we are going to do now. And for that, follow Step 3 Above.

Search → Comment → Drag and Drop to Canvas

Putting Validating Response comments inside the Comments Block

7) Now, to validate the response received (in Scriptworks terms – to assert). Drag the Assert block multiple times onto the canvas for the number of Assertions required and populate them with the information you wish to validate from the REST API response.

Search → Assert → Drag and Drop to Canvas

Search Assert Block from Search Box

Put Multiple Assert Block inside the Canvas

We have added Assert Block. Now, what do we have to Assert? 

We have to Assert the status code and message from the API Response. To get these properties of the Response we use the response properties block. So search for response in the search box and pick the response properties block and drag it into the canvas.

Search → Response → Drag and Drop Response Body into Canvas

search response body from search box present on left hand side panel

choose status code from dropdown

Finally Complete Blocks inside the Canvas

As on PATCH Request, When Updation is done on the back end, we don’t get any message. So we are just capturing Year and validating that here.

8) Now, the final thing is Test Run. Make sure you have followed the prerequisite mentioned above before the Test Run. Make sure you can see Green Symbol before clicking on the play icon.

Highlight Play Button and Scriptworks Client

Finally Pass Pheww...

That’s how we can validate a REST API with the response code and status message in Scriptworks.
