SAP Commissions Rest API Basic Authentication from SAP Advanced Workflow

SAP Commissions Rest API allows 2 types of authentication i.e. Basic Authentication and JWT Token Authentication. Customer can choose any one type of authentication to make api calls from SAP Advanced workflow. This blog post will explain a sample of groovy script in SAP Advanced workflow to make api calls to SAP Commissions using basic authentication.

1) Create custom parameters in advanced workflow to Store commissions api endpoint url and credentials

Path: Set Up → DEVELOPMENT → Custom Parameters → Add New

2) Write a workflow Groovy script of ‘Util’ Type to make api calls to Commissions

Path: Set Up → DEVELOPMENT → Scripts → Add New

code:

def fnPrepareCommHeaders(){
	
    def oHeaders = new java.util.HashMap();      
    oHeaders.put('content-type','application/json');
    oHeaders.put('Accept', 'application/json');
      
    def sUser = resp.getAppParam("comm.api.user");
    def sPassword = resp.getAppParam("comm.api.password");
    def sCredentials = sUser + ":" + sPassword ;
    def b64Credentials = sCredentials.bytes.encodeBase64().toString();
    def sAuthorizationHeader = "Basic " + b64Credentials;
    oHeaders.put('Authorization', sAuthorizationHeader);  
  
    return oHeaders;
}

def fnCallCommissionsAPI(sMethod, sUrl, sBody){
  	
  	def oResponse;
  	def oHttpClient	= resp.createHttpClient();
  	def oHeaders	= fnPrepareCommHeaders();          
  	String sURL 	 = resp.getAppParam("comm.api.uri") + sUrl;  
  	
  	switch(sMethod){		
      	case 'GET':
      		oResponse = oHttpClient.executeHttpGet(sURL, oHeaders);
      		break;
      	case 'POST':
      		oResponse = oHttpClient.executeHttpPost(sURL, 'application/json', oHeaders, sBody);
      		break;      
      	case 'PUT':
      		oResponse = oHttpClient.executeHttpPut(sURL, 'application/json', oHeaders, sBody);
      		break;          
      	case 'DELETE':
      		oResponse = oHttpClient.executeHttpDelete(sURL, oHeaders);
      		break;               
      	default:
          	break;      
    }
    return oResponse;  	
  
}

3) Call above util function from any required script to Get/Create/Update/Delete any commissions resources.

Sample code to get Period Information from Commissions:

import groovy.json.JsonSlurper;
def utilCommApi = resp.importScript("commissions_functions");

def sResponse = utilCommApi.invoke("fnCallCommissionsAPI", 'GET', '/periods','')

def jsonSlurper = new JsonSlurper()
def jsonResponse = jsonSlurper.parseText(sResponse.getContent());
logger.info("Periods-:", jsonResponse);

Conclusion – SAP Commissions can be integrated with Advacned workflow by calling Rest APIs using basic authentication.
