    Name formats

    • Function namemy-function.

    • Function ARNarn:aws:lambda:us-west-2:123456789012:function:my-function.

    • Partial ARN123456789012:function:my-function.

    The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

  • Marker (string) – Specify the pagination token that’s returned by a previous request to retrieve the next page of results.

  • MaxItems (integer) – The maximum number of function URLs to return in the response. Note that ListFunctionUrlConfigs returns a maximum of 50 items in each response, even if you set the number higher.

Response Structure

  • (dict) –

    • FunctionUrlConfigs (list) –

      A list of function URL configurations.

      • (dict) –

        Details about a Lambda function URL.

        • FunctionUrl (string) –

          The HTTP URL endpoint for your function.

        • FunctionArn (string) –

          The Amazon Resource Name (ARN) of your function.

        • CreationTime (string) –

          When the function URL was created, in ISO-8601 format (YYYY-MM-DDThh:mm:ss.sTZD).

        • LastModifiedTime (string) –

          When the function URL configuration was last updated, in ISO-8601 format (YYYY-MM-DDThh:mm:ss.sTZD).

        • Cors (dict) –

          The cross-origin resource sharing (CORS) settings for your function URL.

          • AllowCredentials (boolean) –

            Whether to allow cookies or other credentials in requests to your function URL. The default is false.

          • AllowHeaders (list) –

            The HTTP headers that origins can include in requests to your function URL. For example: Date, Keep-Alive, X-Custom-Header.

            • (string) –

          • AllowMethods (list) –

            The HTTP methods that are allowed when calling your function URL. For example: GET, POST, DELETE, or the wildcard character ( *).

            • (string) –

          • AllowOrigins (list) –

            The origins that can access your function URL. You can list any number of specific origins, separated by a comma. For example:, http://localhost:60905.

            Alternatively, you can grant access to all origins using the wildcard character ( *).

            • (string) –

          • ExposeHeaders (list) –

            The HTTP headers in your function response that you want to expose to origins that call your function URL. For example: Date, Keep-Alive, X-Custom-Header.

            • (string) –

          • MaxAge (integer) –

            The maximum amount of time, in seconds, that web browsers can cache results of a preflight request. By default, this is set to 0, which means that the browser doesn’t cache results.

        • AuthType (string) –

          The type of authentication that your function URL uses. Set to AWS_IAM if you want to restrict access to authenticated users only. Set to NONE if you want to bypass IAM authentication to create a public endpoint. For more information, see Security and auth model for Lambda function URLs.

        • InvokeMode (string) –

          Use one of the following options:

          • BUFFERED – This is the default option. Lambda invokes your function using the Invoke API operation. Invocation results are available when the payload is complete. The maximum payload size is 6 MB.

          • RESPONSE_STREAM – Your function streams payload results as they become available. Lambda invokes your function using the InvokeWithResponseStream API operation. The maximum response payload size is 20 MB, however, you can request a quota increase.

    • NextMarker (string) –

      The pagination token that’s included if more results are available.
