I set up hyperledger fabric on Hyperledger Fabric consortium on Azure Kubernetes Service (AKS) . I have installed https://github.com/hyperledger/fabric-samples/blob/release-1.4/balance-transfer/artifacts/src/github... on the network. I have tested peer invoke and peer query command on azure-cli. It is working properly. Now I want to communicate with this hyperledger network usinghttps://github.com/hyperledger/fabric-samples/tree/release-1.4/balance-transfer. Help me to set up this REST Server.
