[Learn more about Label Studio Enterprise](https://humansignal.com/goenterprise) </p> </Card> Trigger a Dimension label-distribution value-counts backfill for the authenticated user's active organization. Populates MatrixAnnotatorEntry.value_counts and rebuilds the ProjectSummary.dimension_value_counts cache for all tasks, without recomputing agreement scores. Exactly one of three body fields must be provided:

project_id: backfill a single specific project.
num_projects: batched org backfill — queue the next N not-yet-started projects (in ascending project ID order), leaving any currently in-flight jobs untouched. Repeat calls until projects_remaining in the response reaches 0.
all_projects: full org backfill — cancel all in-flight jobs and queue every remaining non-completed project at once.

Requires administrator or owner role and access to Agreement V2 value counts.
