What are Workflow Executions?
An execution is one contact’s journey through a published workflow version. It is created by the Run Workflow API or by starting a campaign, and moves throughpending → running → a terminal status (completed, failed, cancelled or aborted).
On completion, termination_reason carries the label of the end node the contact reached and outcome its declared success / failure / neutral.
Endpoints
These are workflow executions, distinct from call executions. Each agent node inside a workflow execution produces a regular call execution with its own transcript and recording.
