Hi, first of all, thanks for letting me be part of your community and sorry for not using Chinesse. I have an Official Account of type Service Account which is verified (WeChat Verification, with the orange tick in it). I have successfuly linked this Official Account with a Website App so that users are able to log in to my application just scanning a QR code. Now I wonder whether I can do that without a Website App (Open Platform), i.e. using the Official Account appId. I have tried it, but I get this error: [图片] For the scope parameter I am setting `snsapi_login`, as I did when using the WebsiteApp appId. Is it possible to use the qr-based login without a Website App (i.e. directly with an Official Account). If so, am I doing anything wrong? Again, thank you very much for your help!
