I'm building a project for my Master's Software Engineering program, which involves using Bing's mapping API to find and map specific locations based on given addresses. My program has a function which calculates distances from point A to point B based on the Haversine formula. Another function takes the shortest distance and associated address, maps that address, and posts a static map image to a chat channel.
I'm trying to test this functionality. When I don't change my IP via a VPN, it works fine and I can get responses from the API. When I change my IP address via a VPN, all I get from the Bing API is 404 responses and I can't see if my function actually works properly. In addition to me not knowing if my function is working, I'm worried that if other people in other provinces/countries try to use it, it won't work for them, which would ruin a good portion of my application's functionality. Is this a known problem? And how can I deal with it?
