Hi @vibhav - If this is an internal tool used only within your Zoom organization, you can use your Zoom app’s development credentials. These credentials are valid for anyone inside your Zoom organization ([given that it’s used for testing/development](https://developers.zoom.us/docs/build-flow/basic-info/app-credentials/#when-to-use-development-credentials))

If you plan to allow external users to access your Zoom app, then you can still [request a manual app validation](https://devforum.zoom.us/t/domain-validation-explanation/87699) or you can also publish the content on a site related to your app, such as GitHub or Google Docs
