Good Afternoon, We are testing an OAUTH app that previously worked, and we are now getting this error after the agent enters their credentials: Invalid redirect: {url removed for security} (4,700) When we copy and paste this redirect URL into a browser, we get to the page fine. Can you help us with this issue? Thanks, George ---

hi @gschally 4,700 error it’s a whitelisting issue. Zoom does not recognise this as an oauth call from your marketplace entry. you need to make sure this url redirect that you pass during authentication is the same one you also specified in your marketplace information. Have you changed this or have you made sure the url will be different for developer and production versions. - You need two versions otherwise you give yourself problems when you want Zoom to test a new development version., while your previous version works in production. all the best John ---

Hi John, I believe our app was created on the marketplace before the redirect was required in the setup. There does not appear to be a place to specify the URL for whitelisting in our app setup, although I do see it in the new app configuration screens. Our app also works with the call control beta, and I believe it will stop working with that beta if we upgrade to a new app type. Is there a way to specify the URL for whitelisting without changing the app type? This was working at some point in the past without that specification. Thanks, George ---

hi @gschally That URL you are going to in the auth process of the app needs to be put in the marketplace. ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/2/7/27c13f07783cbbcc29cfaa09f24ec629db096223.png) OAUTH has been around forever, so I’m not sure why it’s not shown in your marketplace settings. Yes, you are adding the information to the marketplace, not changing your app. All the best John ---
