Security
App ID
APP ID is your app’s identifier. This, along with your APP secret gives you access to NXG APIs.
App Secret
APP Secret identifies you as an authorized developer. You should NEVER give your APP Secret to a third-party developer or store it directly in your code. Use authorization to grant access to third-party developers.
IP Whitelist
Access of access_token is managed by IP whitelist, i.e only requests from IPs in whitelist are acknowledged.
