# Batch update settings

> Apply the same settings patch to multiple apps — pause or resume a whole cluster.

**`POST`** `https://api-datahub.octoparse.com/v1/data-apps/batch/settings`

Authentication: API key required (`Authorization: Bearer <API Key>`).

Reversible operational switches for a cluster of apps: when upstream changes or rate-limits hit, pause every related app once with the same `pause_message`, then restore once they are fixed; bulk visibility changes work the same way (pair with batch grants: fill the list first, then switch to `shared`). Field semantics match the single-app settings endpoint exactly; this endpoint only applies one patch to many apps.
