Overview
At a minimum journeys contain an entry node, and an exit node.

Journey Nodes
- Entry Node: Define who is allowed to enter a Journey.
- Message Node: Used to message users.
- Wait For Node: Wait for a user to enter a segment.
- Delay Node: Wait for some fixed amount of time to progress.
- Exit Node: Used to mark a user’s exit from a journey.
- Segment Split Node: Condition messages depending on whether they’re in a segment.
Journey Status
Journeys can have one of the three following statuses “Not Started” → “Running” ↔ “Paused”. Journeys begin as “Not Started”, and can be started so that they’re “Running”, at which point they can be “Paused” and unpaused.
