I tried to create a Cloud Connector to implement the interconnection between SmartThings and our account. Now we have successfully called the Authorization URI and returned to SmartThings’ redirect address with state and code parameters.
The location is like this:
https://c2c-us.smartthings.com/oauth/callback?state=eyJhbGciOiJIUzM4NCJ9.MGQ2OGI3NzEtNzZiZi00NTU0LTg5NjgtMGNjMTE2NDc0MDk5OnZpcGVyX2Y2NWI0NzYwLTFmNGYtMTFmMC04NmFkLTQxNmJiZGMwZjMxZjoxNzQ1MzcxMzYxMzkwOmEwNTkyOThiLWI3ZjEtNGY2OS1iNWUxLTYyNGYyMmEzYzc5Mjplbi1VUzo6OnRydWU.uszh5NbD8QGYcncyl9Ck4o4-BuYj3dga9MWsqFRUx35p0RmTJpuFicRRkfREfI2t&code=C65980f6484c21000
However, after the SmartThings App redirects to this address, the page displays {} with no obvious error messages, and our Token URI is not called. What could be the problem?
