<p>Changes the visibility timeout of multiple messages. This is a batch version of <code> <a>ChangeMessageVisibility</a>.</code> The result of the action on each message is reported individually in the response. You can send up to 10 <code> <a>ChangeMessageVisibility</a> </code> requests with each <code>ChangeMessageVisibilityBatch</code> action.</p> <important> <p>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 <code>200</code>.</p> </important> <p>Some actions take lists of parameters. These lists are specified using the <code>param.n</code> notation. Values of <code>n</code> are integers starting from 1.
