# EventInvokeConfiguration
<a name="sam-property-function-eventinvokeconfiguration"></a>

Configuration options for [asynchronous](https://docs.amazonaws.cn/lambda/latest/dg/invocation-async.html) Lambda Alias or Version invocations.

## Syntax
<a name="sam-property-function-eventinvokeconfiguration-syntax"></a>

To declare this entity in your Amazon Serverless Application Model (Amazon SAM) template, use the following syntax.

### YAML
<a name="sam-property-function-eventinvokeconfiguration-syntax.yaml"></a>

```
  [DestinationConfig](#sam-function-eventinvokeconfiguration-destinationconfig): EventInvokeDestinationConfiguration
  [MaximumEventAgeInSeconds](#sam-function-eventinvokeconfiguration-maximumeventageinseconds): Integer
  [MaximumRetryAttempts](#sam-function-eventinvokeconfiguration-maximumretryattempts): Integer
```

## Properties
<a name="sam-property-function-eventinvokeconfiguration-properties"></a>

 `DestinationConfig`   <a name="sam-function-eventinvokeconfiguration-destinationconfig"></a>
A configuration object that specifies the destination of an event after Lambda processes it.  
*Type*: [EventInvokeDestinationConfiguration](sam-property-function-eventinvokedestinationconfiguration.md)  
*Required*: No  
*Amazon CloudFormation compatibility*: This property is similar to the `[DestinationConfig](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/aws-properties-lambda-eventinvokeconfig-destinationconfig.html)` property of an `AWS::Lambda::EventInvokeConfig` resource. SAM requires an extra parameter, "Type", that does not exist in CloudFormation.

 `MaximumEventAgeInSeconds`   <a name="sam-function-eventinvokeconfiguration-maximumeventageinseconds"></a>
The maximum age of a request that Lambda sends to a function for processing.  
*Type*: Integer  
*Required*: No  
*Amazon CloudFormation compatibility*: This property is passed directly to the `[MaximumEventAgeInSeconds](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/aws-resource-lambda-eventinvokeconfig.html#cfn-lambda-eventinvokeconfig-maximumeventageinseconds)` property of an `AWS::Lambda::EventInvokeConfig` resource.

 `MaximumRetryAttempts`   <a name="sam-function-eventinvokeconfiguration-maximumretryattempts"></a>
The maximum number of times to retry before the function returns an error.  
*Type*: Integer  
*Required*: No  
*Amazon CloudFormation compatibility*: This property is passed directly to the `[MaximumRetryAttempts](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/aws-resource-lambda-eventinvokeconfig.html#cfn-lambda-eventinvokeconfig-maximumretryattempts)` property of an `AWS::Lambda::EventInvokeConfig` resource.
