I’ve been trying to get a SmartThings app to work using oAuth and a callback URL. Trouble I’m having is related to access tokens.
I’ve followed various instructions, for example, this one: https://github.com/JasonBSteele/SmartThings
But, whenever I get the URL with the function I need to call, I get the error: “This request is not authorized by the specified access token”
For example, the URL being called is: https://graph-na02-useast1.api.smartthings.com:443/api/smartapps/installations//$APPID/update?access_token=$ACCESSTOKEN
