# ListFunctions
<a name="API_ListFunctions"></a>

Gets a list of all CloudFront functions in your Amazon Web Services account.

You can optionally apply a filter to return only the functions that are in the specified stage, either `DEVELOPMENT` or `LIVE`.

You can optionally specify the maximum number of items to receive in the response. If the total number of items in the list exceeds the maximum that you specify, or the default maximum, the response is paginated. To get the next page of items, send a subsequent request that specifies the `NextMarker` value from the current response as the `Marker` value in the subsequent request.
