**Video SDK Type and Version** zoom-video-sdk-windows-1.10.0 **Description** Cannot create or join a session **Error?** “Unable to create or join a session. Please try again. (Error Code: 1500)” **Troubleshooting Routes** Search of web and forum turned up nothing for this specific error code. **How To Reproduce** 1. Following these directions: [Video SDK - Windows - Get started](https://developers.zoom.us/docs/video-sdk/windows/get-started/) 2. Used Visual Studio 2019 to build with configuration “Release x64” 3. Copied JWT from the credentials page for my application. (Window still showed “token is empty” message, but on re-opening settings the message was gone.) 4. Attempted to create a session. (Same error when attempting to join.) ---

@gabriel2 , Please tag if for response. For the JWT token in step 3, you will need to [generate it yourself](https://developers.zoom.us/docs/video-sdk/auth/#generate-a-video-sdk-jwt) using the SDK Credentials’ - SDK Key and SDK Secret ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/1/7/176f6822357837872967366db6d307e7881d5cba.png) The JWT Token which is shown on the marketplace portal is only for accessing REST API ---

@tien01nx The specific topic here is referring to Video SDK. Your screenshot (JWT token) is referring to a different product (Meeting SDK). If you are using Meeting SDK, could you open a new thread and tag me in the thread. I’ll help you on a different thread to avoid confusion for other users. ---

@tien01nx you will need to sign up for a video SDK account here [Buy it now - Zoom](https://zoom.us/buy/videosdk) Do note that this needs to be on a new email address which does not have any Zoom Meeting associated with it. Once you have signed up for a Video SDK account on a new email address, you should see a different page from what is seen from the screenshot.
