Automatically update certain mandatory fields

Hi Postman Community,

my json body contains values in certain fields that i have to change with every request - how can i automate these field updates without having to change them manually?

This type of activity is covered in the Postman Learning Centre.

If you are new to Postman, then I would suggest a visit to the Learning Centre.

Including the Postman Training links under “Other Resources”.

I would recommend the “Galaxy APIs 101” course first as it gets you used to the application features.

Then the “Galaxy Testing and Automation” course which teaches you how to assert the responses. It includes defining and using variables.

You also might want to consider the collection runner and data files.
