If an entity application has the status pending_action, this endpoint must be used to inform the system of the outcome of the action and advance the application accordingly.
For multi-entity applications, the entity application must be identified by sending either entity_application_token, entity_token, or external_entity_id. See those parameters' descriptions for more detail.
If the action has been configured to expire, the system checks if an action has expired every 12 hours from the time the application visits the action node. The system also checks for expiration if a request to this endpoint is made, and the application will advance according to the journey configuration if the action node has expired.
Additional data can also be optionally sent to the subsequent nodes in order to update the application.
