通过crm工作流程调用Web服务

Question

Currently i'm working on a crm project. In this project i have to send data to web service and take refined data back. This operation must be work on custom workflow but i'm stuck infact i have no idea how to do it? Any suggestions?

Here is my service code; 


var tmpIncident = getIncidentById(organizationServiceContext);
        if (tmpIncident != null) //if we have decent incident we connect service and proceed the data.
        {
            GetCustomerInfoService.TransactionServiceClient client = new GetCustomerInfoService.TransactionServiceClient();
            GetCustomerInfoService.TransactionRequest request = new GetCustomerInfoService.TransactionRequest();


            #region authentication  
            request.AuthenticationData.UserName = "user";
            request.AuthenticationData.Password = "pass";
            #endregion

            Guid id = Guid.NewGuid(); //create random guid
            request.RequestId = id.ToString();
            request.OrderNumber = tmpIncident.vrp_ordernumber;

            GetCustomerInfoService.TransactionResponse response = client.GetTransactionByOrderNumber(request);
            tmpIncident.CustomerId = new EntityReference("Contact", new Guid(response.Message));


            this.updateChanges(organizationServiceContext, tmpIncident);

            client.Close();
        } 

When i tested plugin, i received that error;

Error Message:

Assuming that you are using Dynamics CRM. This is a high-level overview:

1. Create a custom workflow activity that makes the actual call to the webservice. This should help you get started: https://msdn.microsoft.com/en-us/library/gg328515.aspx
2. The custom activity would have output parameters that would return the results from the webservice back to the calling CRM workflow.
3. Finally create the workflow and its triggers that would make use of your custom activity. More info: http://crmbook.powerobjects.com/system-administration/processes/workflows/ https://msdn.microsoft.com/en-us/library/gg328264.aspx

I hope this is enough information to get you heading down the right path.
