Cloud Endpoints are persistent, globally available on the ngrok network and can accept traffic on a URL like https://api.your-company.com. They take action entirely within our network and route to other endpoints. Internal Agent Endpoints are created alongside a secure tunnel by the ngrok agent and run on a URL like https://your-api.internal, which means they can only accept traffic from another endpoint owned by your ngrok account. Traffic Policy is a configuration language that lets you orchestrate requests as they pass through any of your endpoints, allowing for security, flexibility, and high availability. The composable shape of the API gateway allows users to mix-and-match components to build the perfect API gateway for their needs, with features such as forward-internal actions, CEL interpolation, and centralized policy on cloud endpoints.
