Request Syntax

response = client.update_function_url_config(
    FunctionName='string',
    Qualifier='string',
    AuthType='NONE'|'AWS_IAM',
    Cors={
        'AllowCredentials': True|False,
        'AllowHeaders': [
            'string',
        ],
        'AllowMethods': [
            'string',
        ],
        'AllowOrigins': [
            'string',
        ],
        'ExposeHeaders': [
            'string',
        ],
        'MaxAge': 123
    }
)

Parameters

FunctionName (string) --
[REQUIRED]

The name of the Lambda function.

Name formats
- Function name – my-function .
- Function ARN – arn:aws:lambda:us-west-2:123456789012:function:my-function .
- Partial ARN – 123456789012: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.
