# Amazon.Lambda.S3Events

This package contains classes that can be used as input types for Lambda functions that process Amazon Simple Storage Service (Amazon S3) events.

This package has a dependency on the [AWS SDK for .NET package AWSSDK.S3](https://www.nuget.org/packages/AWSSDK.S3/) in order to use the `Amazon.S3.Util.S3EventNotification` type.

# Serialization
86

97
If you are using this package with Amazon Lambda but are not also using `Amazon.Lambda.Serialization.Json`, be aware that two properties require custom serialization. These properties are both part of the `Amazon.S3.Util.S3EventNotification+ResponseElementsEntity` class.
108
1. `XAmzRequestId` should be treated as `x-amz-request-id`
119
2. `XAmzId2` should be treated as `x-amz-id-2`
1210

13-
A Newtonsoft.Json `IContractResolver` implementation which handles this custom serialization is located in [Amazon.Lambda.Serialization.Json\AwsResolver.cs](../Amazon.Lambda.Serialization.Json/AwsResolver.cs), consult this source for more information.
