If you’re new to Katalon Studio and looking to make an API request using data read from an Excel sheet, you’re in the right place. This guide will walk you through the process with clear steps to ensure you can efficiently utilize Katalon Studio for your testing needs.

Step-by-Step Guide to Making API Requests in Katalon Studio

1. Variable Creation

The first step in the process is to create variables within Katalon Studio. These variables will be used to store the data that you retrieve from your Excel sheet.

2. Retrieve Data from Excel/CSV

Katalon Studio allows you to retrieve data directly from an Excel or CSV file. To do this, choose “Test Data Value” from the Type dropdown, then select your file. You will need to specify the column and row number to extract the specific data you need for your API request.

3. Call Variables in Your Test Case

Once you have your variables set up and your data retrieved, the next step is to call these variables within your test case. This involves using the variables created in the first step to parameterize your test case and web service requests. This approach allows for dynamic data input, making your test cases more robust and flexible.
