Is it possible to make a mock service emulating async microservice?

Hi!

Could you help me, please.
I need to make a mock? that will recieve request with parameter “replyToUrl”, give a sync answer (empty body, 202 status code), than invoke new request with some predefined body with endpoint = “replyToUrl”.
Is it possible to make such mock server in Postman?

I did’t find any useful information in https://learning.postman.com/docs

Thanks
