External access allows remote access to the contents of your Instance data, including the ability to make updates.
See Introspection/API for a list of all commands available to External systems.
External access allows the developer to execute any command against your instance, regardless of their own personal permissions ; enabling a developer for external access requires trust and is granting a large set of permissions. While commands like 'delete' are usually disabled to External access, a malicious actor could make quite the mess of your data and configuration.
Please report any developer abuse to Iain Maltz
Developers may discover how to use the External interface here.
