Hey team, I am an apprentice from Germany and I am currently in my first year of training :). So I don’t know to much about using APIs at all. My company gave me the order to use the Zoom API. So started to learn more about Nodejs. As the documentation says I need to use OAuth to get the data from the API I want. I created an OAuth app in the app marketplace and a Nodejs script that handles these request. I successfully created a Nodejs script that calls the Meeting API and shows me my created Meeting when I click on “install” in my app on the app marketplace. So far so good. My goal is to create an Nodejs script which I can call from my PC that makes an request to the Zoom API. The problem which I got is the authentication. When I do the first POST request to this URL: [https://zoom.us/oauth/authorize](https://zoom.us/oauth/authorize) with the parameters which where described here: [https://marketplace.zoom.us/docs/guides/auth/oauth](https://marketplace.zoom.us/docs/guides/auth/oauth) I wont get my authorization code. I probably know why. Its because i am not logged in with my Zoom account. Is their any chance to access the API without a login? Or do you know how I can access the authorization code without clicking on the “install” button in the browser when i am logged in? I hope you can help me with this problem 🙂 Thanks, Marvin ---

Hi @Marv! The authorization code is returned as a query parameter of the Redirect URL. Check our [OAuth Sample App](https://github.com/zoom/zoom-oauth-sample-app/blob/master/index.js#L19) for how to check for this and then handle the request for an access token. Are you not receiving this code in this query parameter? ---

Hey @michael.zoom I am getting the authorization code. But the Problem is i want to authenticate myself through a Nodejs script. At the moment i logging in from the App Marketplace and start my App. But i want to authenticate myself not through the browser. ---

Hey @Marv, You should use the [JWT auth flow](https://marketplace.zoom.us/docs/guides/auth/jwt) instead. 🙂 Thanks, Tommy ---
