The type of authentication that your function URL uses. Set to <code>AWS_IAM</code> if you want to restrict access to authenticated users only.

<p>Use one of the following options:</p> <ul> <li> <p> <code>BUFFERED</code> – This is the default option. Lambda invokes your function using the <code>Invoke</code> API operation. Invocation results are available when the payload is complete. The maximum payload size is 6 MB.</p> </li> <li> <p> <code>RESPONSE_STREAM</code> – Your function streams payload results as they become available. Lambda invokes your function using the <code>InvokeWithResponseStream</code> API operation. The maximum response payload size is 20 MB, however, you can <a href="https://docs.aws.amazon.com/servicequotas/latest/userguide/request-quota-increase.html">request a quota increase</a>.</p> </li> </ul>
