No problem 
If you are using Heimdall as your alarm system, follow this guide: Ring Security - Extend Heimdall with Ring Security products
If you just want to set a code to trigger flows you need to use the “Ring Security” app.
You do not configure any code in the keypad. When you enter a code and press e.g. arm button this card will be triggered: “Key sequence entered”.
The tag will hold the code entered and what button was pressed. Then act on that with logic cards.
