Citizens should reach the production licensing API at api.city.gov rather than the default execute-api URL, and that hostname must map to the prod stage. What configuration achieves that?
Select an answer to reveal the explanation.
Short Explanation
api.city.gov is the polished storefront address—map it to the prod stage, not the warehouse code on the loading dock. Custom domains beat asking people to memorize execute-api URLs. Pointing the public name at test mixes paint colors.
Full Explanation
API Gateway custom domains provide stable hostnames mapped to specific stages. Binding api.city.gov to the prod stage gives clean environment routing for citizens while keeping execute-api URLs for internal use if needed. Mapping the public hostname to test, or avoiding custom domains entirely, muddies environment separation.
