Global Context

The global context includes the following variables:

Current Date and Time

$system_timeAn ISO 8601 string for the current UTC time.e.g. "14:37:23.000000"
$system_dateAn ISO 8601 string for the current UTC date.e.g. "2022-07-14"
$system_datetimeAn ISO 8601 string for the current UTC date and time.e.g. "2022-07-14T14:37:23.000000"

Every time the content of the variables is read, it will reflect the date and time at that particular point in time.

Number of Bot Messages

The system will keep track of the number of messages sent to the user. This could be useful in some situations, for example when resuming a flow and deciding what to do based on how long the conversation history was.

$eventEvent object.
$intentIntent object with the properties name and entities.
$entitiesDirect access to $intent.entities.
$utteranceUtterance object with the last message from the bot.

$active_flowsList of the names of all active flows. If there are multiple instances, the name of a flow will appear only once.e.g. ["ask_name", "hello", ...]
$active_labelsList of the label names in all active flows. The labels are prefixed with the name of the flow i.e. "FLOW_NAME.LABEL_NAME"e.g. ["ask_name.wait_name", ...]
$expected_nextList of the names of all intents expected next.

Local Flow Variables
