Call Flows

Deploy call flow version

Changed on Aug 20, 2026

Makes one saved Call Flow version active, selected by document version or version ID. Use it after updating a visual flow when that revision is ready to handle calls; updating the Call Flow saves a revision but does not replace this deployment step. Directly authored SWML Scripts do not use Call Flow versions.
