# Batch grants

> Share multiple apps with multiple users in one call. Matrix semantics, idempotent.

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

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

Open multiple apps you own to multiple users in one call (matrix semantics, idempotent). Storage and effective rules match single-user grant. Each username is resolved once. `granted` counts only **new** pairs; pairs already on the list are skipped idempotently so you can tell “3 added, 2 already present”.
