Migrating from Sandbox environment

Hello,

I have passed the review and have an issue: what is login and password for Production environment for application? I have main login and password, but when I try to use them, I get error: "The requested feature is not available".

I use Python RingCentral library

My code

sdk = SDK(settings.RC_APP_KEY, settings.RC_APP_SECRET, settings.RC_APP_SERVER_URL)
platform = sdk.platform()  platform.login(settings.RC_APP_USERNAME, settings.RC_APP_USER_EXT, settings.RC_APP_PASSWORD)      data = {   "to": [{"phoneNumber": phone}],   "from": {"phoneNumber": settings.SMS_FROM_PHONE},   "text": message,   }

res = platform.post(url=settings.SMS_URL, body=data)

And it works in Sndbox environment. What is the account credentials for Production environment?
