Run Context

Basic information about the run's state and the user invoking the flow is provided through a "virtual", read-only property available at the JSONPath $._context. This path may be used in a path for a Parameters value on an action or Pass state type, or in expressions which are evaluated when generating Parameters values as described above. This allows the flow to refer to these values as parameters to various states. As this is a read-only value, the _context cannot be overwritten by using the path in a ResultPath on any state. The _context value is itself an object containing the following properties:

Property name	Description
flow_id	The id of the flow that is being executed
flow_title	The title of the flow at execution start time (This will not reflect changes made to the title after execution start time)
run_id	The unique id assigned to this run (execution) of the flow
run_label	The label assigned to this run (execution) of the flow (This will not reflect changes made to the label after execution start time)
username	The Globus Auth username for the user invoking the flow
email	The email address for the user invoking the flow
user_id	The Globus Auth user id for the user invoking the flow (in URN format)
identities	A list of all identities associated with the user invoking the flow (in URN format)
token_info	A child object containing the fields `exp`, `iat`, and `nbf` (described below)

The token_info fields are defined as follows:

exp: Timestamp, measured in the number of seconds since UTC January 1, 1970, indicating when this token will expire.
iat: Timestamp, measured in the number of seconds since UTC January 1, 1970, indicating when this token was originally issued.
nbf: Timestamp, measured in the number of seconds since UTC January 1, 1970, indicating when this token is not to be used before.
