Display password stored in System Properties

I had to look at an existing interface in production which sends data to an external system. The interface is working well but we don’t have any documentation. I like to use POSTMAN to send some test requests to figure out how the API works. Unfortunately, the API password is kept in a System Properties and is masked and encrypted.

I struggled for a while until I realized, since System Properties are meant to be accessible by code, it means, I can easily retrieve and display the value from code. So I created an automation script on the Save event of the ASSET object to display the value:

The code has a filter on a specific asset to minimize the chance it can cause trouble to other end-users who might update Asset data while I’m doing this. This is my favorite approach when I want to run some code on production.
