# Plannings

## List planning changesets (timeline)

 - [GET /v1/plannings/{id}/changesets/](https://docs.adm.wearetransformers.nl/apis/schema/plannings/v1_plannings_changesets_retrieve.md): Returns compact changeset summaries for this planning (timestamp, status, source, and counts). Use the changeset detail endpoint for full per-entity diffs.

## Get planning changeset details

 - [GET /v1/plannings/{id}/changesets/{change_id}/](https://docs.adm.wearetransformers.nl/apis/schema/plannings/v1_plannings_changesets_retrieve_2.md): Returns one changeset with full per-entity diffs for AuditLog expansion.

## Get planning metrics

 - [GET /v1/plannings/{id}/metrics/](https://docs.adm.wearetransformers.nl/apis/schema/plannings/v1_plannings_metrics_retrieve.md): Get metrics for the planning at a specific point in time. Use change_id to get metrics at a specific changeset (historical state). Use mainline=true to explicitly get mainline metrics (ignores workspace header). Omit both for current metrics (workspace if header provided, mainline otherwise).
