Hi @elisa.zoom , I have used this github repository ,also able to join or start meeting .But, i need to go to login to my zoom marketplace app and allow user to get authorization code all times for access-token and ZAK token. Is there any other way to get access-token and ZAK token to allow a group of users without login again and gain to my marketplace account to allow users for generating authorization code. And one more enquiry is about app publishing. Is it necessory to first integrate zoom sdk fully in my app before publishing to zoom marketplace ---

Hi @adityaXenelsoft So if you want users outside of your account to join the meeting, you must publish your app in the Zoom Marketplace > **[App distribution - Zoom Developers](https://developers.zoom.us/docs/distribute/)** > > The Zoom Developer Platform is an open platform that allows third-party developers to build applications and integrations upon Zoom’s video-first unified communications platform. ---
