Represents a permission statement that can be added to a Lambda's resource policy via the
|principal||The entity for which you are granting permission to invoke the Lambda function.|
|action?||The Lambda actions that you want to allow in this statement.|
|event||A unique token that must be supplied by the principal invoking the function.|
|source||The AWS account ID (without hyphens) of the source owner.|
|source||The ARN of a resource that is invoking your function.|
The entity for which you are granting permission to invoke the Lambda function.
This entity can be any valid AWS service principal, such as s3.amazonaws.com or sns.amazonaws.com, or, if you are granting cross-account permission, an AWS account ID. For example, you might want to allow a custom application in another AWS account to push events to Lambda by invoking your function.
The principal can be either an AccountPrincipal or a ServicePrincipal.
(optional, default: 'lambda:InvokeFunction')
The Lambda actions that you want to allow in this statement.
you can specify lambda:CreateFunction to specify a certain action, or use
a wildcard (
lambda:*) to grant permission to all Lambda actions. For a
list of actions, see Actions and Condition Context Keys for AWS Lambda in
the IAM User Guide.
(optional, default: The caller would not need to present a token.)
A unique token that must be supplied by the principal invoking the function.
The AWS account ID (without hyphens) of the source owner.
For example, if you specify an S3 bucket in the SourceArn property, this value is the bucket owner's account ID. You can use this property to ensure that all source principals are owned by a specific account.
The ARN of a resource that is invoking your function.
When granting Amazon Simple Storage Service (Amazon S3) permission to invoke your function, specify this property with the bucket ARN as its value. This ensures that events generated only from the specified bucket, not just any bucket from any AWS account that creates a mapping to your function, can invoke the function.
