Call to rest API from node JS

Im new to node JS and I need to call the following Rest API when I got call from specific path ,For example If I listen to port 3000 and I got in the path call something like CUSTOMER/3 call to the following rest.

After I read about the node and the module I think that I should use express but not sure how, since I can get request to provide the path to CURSTOMER/4 or even EMPLOYEE/5 and I should route it to another place…

Please provide example 🙂
