Integrating Smart Devices via API: OAuth2 Parameters Needed

Hey everyone! I’m really excited about diving into the world of smart home automation and I’m currently exploring how to use the API to monitor my devices. I’ve managed to get an OAuth2 token and I’m using the auth URL, but I’m a bit stuck on the next steps. I have a token, which is a 36-digit hex number, and I’m using the auth-global.api.smartthings.com URL, but I’m missing the redirect URI and the state parameters. Does anyone know where I can find these? I’ve looked through some documentation, but I’m not entirely sure where to look next. Any guidance would be greatly appreciated! I’m really looking forward to getting this set up and seeing how it can enhance my smart home experience. Thanks in advance for your help!
