Lambda Permission

The AWS::Lambda::Permission resource grants an AWS service or another account permission to use a function. You can apply the policy at the function level, or specify a qualifier to restrict access to a single version or alias. If you use a qualifier, the invoker must use the full Amazon Resource Name (ARN) of that version or alias to invoke the function. To grant permission to another account, specify the account ID as the Principal. To grant permission to an organization defined in AOlong, specify the organization ID as the PrincipalOrgID. For AWS services, the principal is a domain-style identifier defined by the service, like s3.amazonaws.com or sns.amazonaws.com. For AWS services, you can also specify the ARN of the associated resource as the SourceArn. If you grant permission to a service principal without specifying the source, other accounts could potentially configure resources in their account to invoke your Lambda function. If your function has a function URL, you can specify the FunctionUrlAuthType parameter. This adds a condition to your permission that only applies when your function URL's AuthType matches the specified FunctionUrlAuthType. For more information about the AuthType parameter, see [Control access to function URLs](https://docs.aws.amazon.com/lambda/latest/dg/urls-auth.html). This resource adds a statement to a resource-based permission policy for the function. For more information about function policies, see [Lambda Function Policies](https://docs.aws.amazon.com/lambda/latest/dg/access-control-resource-based.html).
