how to identify the API's filter parameters in postman.

Hi experts,

I am using the postman to get some data of the API.But I find out that the API generated from the CPI couldn't identity the parameters that I added and thus the filter conditions doesn't work.For example,I just want to get some records of the employeeA, but it always returned all records of the employees to me. I really have on idea what should I do to filter some data of the API by using the postman.

below is the integration I created on the CPI

and then I copy the endpoint to the postman and try to add some filter conditions but it didn't work!

Could anyone help me to solve the issue?Super thank!!!
