Security data Api requests.

Hey All.
I am using Webflow + Wized + Xano to make a webapp, the problem is that in the Network tab, I can see all the requests I have in each page of my website, with endpoints, methods, if requested or not, so, I think it is a security issue, I am trying to set security for all my endpoints, how is the best practice to do this, and prevent a user to copy the endpoint with the auth token and make requests in postman for example.
