How to change the address shown in the address bar into a shortened address, while the actual access address remains the same?

For example, my request URL is "https://ift.tt/3g69aXz" and I want to only show "https://ift.tt/23AdZdS" on the address bar and hide the "/api". The actual interface is still "https://ift.tt/3g69aXz, but the "/api" is removed when it is displayed. How to implement this? Thank you very much!
