# ChangeMessageVisibilityBatch
<a name="API_ChangeMessageVisibilityBatch"></a>

Changes the visibility timeout of multiple messages. This is a batch version of ` ChangeMessageVisibility.` The result of the action on each message is reported individually in the response. You can send up to 10 ` ChangeMessageVisibility ` requests with each `ChangeMessageVisibilityBatch` action.

**Important**  
Because the batch request can result in a combination of successful and unsuccessful actions, you should check for batch errors even when the call returns an HTTP status code of `200`.
