Hi Govarthini,

You can refer to this question, for the implementation of interdependent dropdowns,

https://forum.mendix.com/link/questions/119063

here I have explained the whole use case, and for the Rest call, just pass the country as a query when fetching the states by get call and do the same for states, in the on change microflow,

Let me know If you face any issue.

Hope it helps!
