# AWS::CloudFront::Distribution GrpcConfig
<a name="aws-properties-cloudfront-distribution-grpcconfig"></a>

Amazon CloudFront supports gRPC, an open-source remote procedure call (RPC) framework built on HTTP/2. gRPC offers bi-directional streaming and binary protocol that buffers payloads, making it suitable for applications that require low latency communications.

To enable your distribution to handle gRPC requests, you must include HTTP/2 as one of the supported `HTTP` versions and allow `HTTP` methods, including `POST`.

For more information, see [Using gRPC with CloudFront distributions](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/distribution-using-grpc.html) in the *Amazon CloudFront Developer Guide*.
