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.

action
(String) The action that the principal can use on the function. For example, lambda:InvokeFunction
or lambda:GetFunction
.function_name
(String) The name of the Lambda function, version, or alias.
Name formats
my-function
(name-only), my-function:v1
(with alias).arn:aws:lambda:us-west-2:123456789012:function:my-function
.123456789012:function:my-function
.You can append a version number or alias to any of the formats. The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.
principal
(String) The AWS-service or AWS-account that invokes the function. If you specify a service, use SourceArn
or SourceAccount
to limit who can invoke the function through that service.event_source_token
(String) For Alexa Smart Home functions, a token that the invoker must supply.function_url_auth_type
(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.principal_org_id
(String) The identifier for your organization in AOlong. Use this to grant permissions to all the AWS-accounts under this organization.source_account
(String) For AWS-service, the ID of the AWS-account that owns the resource. Use this together with SourceArn
to ensure that the specified account owns the resource. It is possible for an Amazon S3 bucket to be deleted by its owner and recreated by another account.source_arn
(String) For AWS-services, the ARN of the AWS resource that invokes the function. For example, an Amazon S3 bucket or Amazon SNS topic.
Note that Lambda configures the comparison using the StringLike
operator.id
(String) Uniquely identifies the resource.permission_id
(String)Import is supported using the following syntax:
$ terraform import awscc_lambda_permission.example <resource ID>
