The Zoom App platform allows developers to create custom apps that can interact with Zoom meetings and user accounts in real-time. By using ngrok, a tool for exposing local APIs to the internet, users can create and deploy their own Zoom Apps, which can be used to trigger various activities such as sharing screens, updating profile information, or manipulating meeting settings. The platform offers fine-grained control over API access, event subscriptions, and OAuth scopes, allowing developers to customize their app's behavior and functionality. Users can secure their apps by verifying webhooks and modifying the connection between ngrok and Zoom. With this flexibility and customization options, developers can build innovative solutions for businesses and individuals alike.
