Keys and secrets
There are four kinds of secrets/keys used in the Health Bot Service as keys:
app_secret is used to secure communications between the partner and the Health Bot Service and is determined by the user security setting.
webchat_secret is used to secure communications between the partner application and the Health Bot Service.
API_JWT_secret is used for securing the management API; for example, the programmatic import/export of scenarios.
Instrumentation key is the Application Insights key provided by the Bot's administrator to collect runtime data including errors and warnings.
