You can trigger journeys based on an event that happens in the site, like when members join.
| Available in: Enterprise, Professional, Unlimited, and Developer editions. |
For an event to trigger a journey, the object that the event happens to must be workflow-enabled. Most standard objects in Salesforce (such accounts, leads, case, and opportunity), all custom objects, and many community-specific objects are workflow enabled. Some site-specific objects, however, aren’t.
Note As a best practice, create sample journeys to make sure that the objects you want to use
can trigger a journey and the data is accessible.
