# Asynchronous function invocation

{% note info %}

This feature is at the [Preview](../../overview/concepts/launch-stages.md) stage.

{% endnote %}

When you create a new function version, you can set up asynchronous invocation to invoke the function without waiting for it to complete.

To invoke a function asynchronously, specify the `?integration=async` request string parameter. When invoked this way, a function cannot parse or set HTTP headers:
* HTTPS request body content is provided as the first argument (without converting to a JSON structure).
* HTTPS request body content is the same as the function's response (without converting and checking the structure); the HTTP response status is `202`.

You have the option to either ignore the function's output or send it to Yandex Message Queue.
