PATCH /v1/layers/:layerId/optimizer/write-classes

Layers' optimizer evaluates many write classes (creative push/replace, targeting, schedule, structural budget tweaks, etc.). At the org level these are gated by GrowthBook flags — too coarse for partners running many projects per org.

This endpoint exposes per-layer overrides. Each flag in the body sets a Boolean on project_layers.config.optimizer for one specific write class.

Body

The optimizer reads per-layer flags first, falling back to the org-level GrowthBook flag when a per-layer flag is unset.
