SellApp
API ReferenceCatalog plans

Catalog plan and apply

Preview a multi-resource catalog change, then apply it atomically.

A plan validates up to 100 ordered operations and shows snapshots, diffs, warnings, and whether the change is destructive. Nothing is written until apply. Plans expire after 15 minutes; stale expectations return 409 catalog_plan_stale; a failed apply leaves no partial writes.
