How to generate and send out the GraphQL data format . Output file should be GraphQL format

Hi Team,

Once of my customer what the data in the format of  GraphQL . Customer API need the  GraphQL data to recive their API. In oracle soa suite, we know that we can transfer the data in the format of XML and JSON format , I have tried to create the xsd for this once in the online and REST adapter am getting the error "Schema generation Failed" . We have data in below

mutation {

        updateECRD(

          update:{

            loadId: "16228",

            ecrd: "2021-05-31T13:01:09+00:00"

          }) {

          transactionId

          status

          errors {

            message

          }

        }

      }

If any one worked in this requirement suggest me. We want send the GraphQL data to the customer API , Customer api accept the format only in GaraphQL structure.
