+# AddLayerVersionPermission<a name="API_AddLayerVersionPermission"></a>
+
+Adds permissions to the resource\-based policy of a version of a function layer\. 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\.

+Lambda function access policy is limited to 20 KB\.  
+HTTP Status Code: 400

 # CreateEventSourceMapping<a name="API_CreateEventSourceMapping"></a>
 
-Identifies a poll\-based event source for a Lambda function\. It can be either an Amazon Kinesis or DynamoDB stream\. AWS Lambda invokes the specified function when records are posted to the event source\.
+Creates a mapping between an event source and an AWS Lambda function\. Lambda reads items from the event source and triggers the function\.
 
-This association between a poll\-based source and a Lambda function is called the event source mapping\.
-
-You provide mapping information \(for example, which stream or SQS queue to read from and which Lambda function to invoke\) in the request body\.
-
-Amazon Kinesis or DynamoDB stream event sources can be associated with multiple AWS Lambda functions and a given Lambda function can be associated with multiple AWS event sources\. For Amazon SQS, you can configure multiple queues as event sources for a single Lambda function, but an SQS queue can be mapped only to a single Lambda function\.
-
-You can configure an SQS queue in an account separate from your Lambda function's account\. Also the queue needs to reside in the same AWS region as your function\. 
-
-If you are using versioning, you can specify a specific function version or an alias via the function name parameter\. For more information about versioning, see [AWS Lambda Function Versioning and Aliases](https://docs.aws.amazon.com/lambda/latest/dg/versioning-aliases.html)\. 
-
-This operation requires permission for the `lambda:CreateEventSourceMapping` action\.
+For details about each event source type, see the following topics\.
