Hey, I have updated the data using post request but I want to check if that data is get saved or not how should I validate this?
Check to see if your database\application has an API that you can retrieve the data and use that.
If you haven’t already done so, I would recommend the Postman Learning Centre.
Under the Postman Training pages, I would recommend the “Galaxy APIs 101” course first, then the “Galaxy Testing and Automation” courses as a starting point.
The second course will teach you how to string requests together.
