/2015-03-31/functions/{FunctionName}/policy

Grants an Amazon Web Services 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. For Amazon Web Services services, the principal is a domain-style identifier defined by the service, like s3.amazonaws.com or sns.amazonaws.com. For Amazon Web Services 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.

This action adds a statement to a resource-based permissions policy for the function. For more information about function policies, see Lambda Function Policies.
