Intercepting requests in Api Gateway

Question

Is it possible to intercept the requests in API Gateway. I am using Netflix Zuul. I am routing the requests to other services(service_1 and service_2) from this gateway. I want to intercept the requests that are coming in this pattern (api/service_1/**) so that I can check for some conditions in request and if those conditions met, I will form a response in API Gateway without letting the request routed to servie_1. Is this possible? If so, kindly give me some useful references. Any help is greatly appreciated. Thanks in advance.

There is a filtering option in Spring, and it will be helpful to you, please check the below one.
