Integrating Salesforce Rest API with SFCC

1. The process is to integrate the Sales cloud and commerce cloud using REST API. The aim is to generate leads in the Sales clou1d by making a callout in SFCC.

2. Below is the apex code to generate lead :

   @RESTResource(urlMapping='/LeadCreate/')
global class CreateLeadApi {
@HTTPPost
global static String creatingLeadRecord(){
String fName,lName, comp;
String fieldName, fieldValue;
RestRequest req = RestContext.request;
RestResponse res = RestContext.response;
String jsonBody=req.requestBody.toString(); //this is the method to get the body
JSONParser parser=JSON.createParser(jsonBody); while(parser.nextToken()!=null){
        if(parser.getCurrentToken()!=JSONToken.END_OBJECT){
            fieldName=parser.getCurrentName();
            fieldValue=parser.getText();
          if(fieldName=='FirstName'){
                fName=fieldValue;  }
             else if(fieldName=='LastName'){
                lName=fieldValue;
            }
              else if(fieldName=='Company'){
                comp=fieldValue;
            }
        }
    }

    Lead l=New Lead(FirstName=fName,LastName=lName,Company=comp);
    insert l;
    return l.Id;
}}

3. Using Postman, the API is tested to check whether leads are getting generated. A token is generated in postman and used in SFCC for authentication while making service call.
