# Application integration


Deploy [Amazon API Gateway](https://docs.aws.amazon.com/apigateway/latest/developerguide/welcome.html) to extract data out of SAP S/4HANA via `HTTP` API. API Gateway can consume data from IDOC, BAPI, and RFC. These need to be translated to a web service call. For more information, see [AWS blogs](https://aws.amazon.com/blogs/awsforsap/category/application-services/amazon-api-gateway-application-services/). The following image shows this scenario.
