# Batch update policies

To modify multiple policies at the same time, you can batch requests with
[`batchModify`](https://developers.google.com/chrome/policy/reference/rest/v1/customers.policies.orgunits/batchModify).
Requests can only be batched together if the meet all the following criteria:

1. Refer to the same target resource (Organizational Unit)
2. Share the same namespace (schemas differ only on the leaf).

   **Example:** You can batch `chrome.devices.A` and `chrome.devices.B`, but not
   `chrome.devices.A` and `chrome.devices.managedGuest.B`.
3. If schemas are keyed, the same keys must be present, but can have different values.

   **Example:** You can modify settings of different printers in the same
   Organizational Unit.

> [!NOTE]
> **Note:** Modifying multiple policies at once in a single [`batchModify`](https://developers.google.com/chrome/policy/reference/rest/v1/customers.policies.orgunits/batchModify) request is recommended to reduce the number of requests to the server.
