+
+Adds permissions to the resource\-based policy of a version of an [AWS Lambda layer](https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html)\. Use this action to grant layer usage permission to other accounts\. You can grant permission to a single account, all AWS accounts, or all accounts in an organization\.
+
+To revoke permission, call [RemoveLayerVersionPermission](API_RemoveLayerVersionPermission.md) with the statement ID that you specified when you added it\.
