Parameters
  • FunctionName (string) --

    [REQUIRED]

    The name of the Lambda function.

    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.

  • Qualifier (string) -- The alias name.
  • 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.
  • 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: https://www.example.com , 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.
