Create Hyperledger Fabric Service Keys

In the usual development process, an SAP Cloud Platform based application is deployed and bound to the Hyperledger Fabric channel. Part of the binding information is the credentials required by the application to access the channel via (micro service) APIs. This information is stored securely within the SAP Cloud Platform and only available to the bound application via its environment.

However, if you need to test the APIs from the browser, then the security credentials must be known to the browser and therefore to the user.

When a service key is created, it consists of the following elements:

{
  "type": "hyperledger-fabric",
  "channelId": "example-channel-id",
  "serviceUrl": "https://hyperledger-fabric.cfapps.eu10.hana.ondemand.com/api/v1",
  "documentationUrl": "https://help.sap.com/viewer/p/HYPERLEDGER_FABRIC",
  "oAuth": {
    "clientId": "example-clientID",
    "clientSecret": "example-client-secret",
    "url": "example-url.com",
    "identityZone": "global-account"
  }
}

It is the clientID and clientSecret that are particularly relevant to you when testing your recently deployed chaincode.
