In this article, I’d be articulating on how to retrieve list of installed workflows in SharePoint 2013 Office 365 site using Client Side Object Model (CSOM). Just to give a background the workflow framework in SP 2013 has undergone a major revamp, there are new WorkflowServicesManager and WorkflowDeploymentService objects, we’d also be leveraging the new APIs accordingly to retrieve

Create a console application and name it as ‘RetrieveInstalledWorkflows’.

Add references to the following dll’s.

Microsoft.SharePoint.Client.dll
Microsoft.SharePoint.Client.Runtime.dll
Microsoft.SharePoint.Client.WorkflowServices.dll

Import the following namespaces

using Microsoft.SharePoint.Client;
using Microsoft.SharePoint.WorkflowServices;
using Microsoft.SharePoint.Client.WorkflowServices;
using Microsoft.SharePoint.Client.Workflow;

Create a static method by name ‘RetrieveInstalledWorkflows’ and implement the following snippet of code.

public static void RetrieveInstalledWorkflows()
{
    Uri oUri = new Uri(“https://yoursite.sharepoint.com”);
   
  
    Office365ClaimsHelper claimsHelper = new Office365ClaimsHelper(oUri, “userid@yoursiter.onmicrosoft.com”, “your password”);
    using (ClientContext oClientContext = new ClientContext(oUri))
    {      

        oClientContext.ExecutingWebRequest += claimsHelper.clientContext_ExecutingWebRequest;
       
        //Get the instance of Workflow Services Manager
        WorkflowServicesManager oWorkflowServicesManager = new WorkflowServicesManager(oClientContext,oClientContext.Web);

        //Hook to WorkflowDeploymentService
        WorkflowDeploymentService oWorkflowDeploymentService = oWorkflowServicesManager.GetWorkflowDeploymentService();

        //Fetch all the installed workflows
        var oWorkflowDefinitionCollection = oWorkflowDeploymentService.EnumerateDefinitions(true);
        oClientContext.Load(oWorkflowDefinitionCollection);

 
        oClientContext.ExecuteQuery();

        foreach(var oWorkflowDefinition in oWorkflowDefinitionCollection)
        {
            Console.WriteLine(“Workflow”+oWorkflowDefinition.DisplayName);
        }

        Console.ReadLine();

    }

}
