WorkflowGen and Microsoft Graph integration samples

Overview

You can use the Microsoft Graph API to create integration points between WorkflowGen and Office 365 applications such Outlook, Excel, Teams, OneDrive, SharePoint, and Azure.

This repository includes the Advantys.Workflow.Applications.MicrosoftGraph.dll assembly and the associated Visual Studio project. This assembly exposes multiple methods that can be used as WorkflowGen applications for each integration feature.

docs: Workflow applications documentation

processes: Process definition file examples

src: Visual Studio solution

Prerequisites

  • Office 365 licences (one license for each user that will be accessing Office applications)

  • Access to an Azure portal: https://portal.azure.com/

  • A service account with an Office 365 licence (such as workflowgen@YOUR_DOMAIN.com)

  • Workflowgen.My.dll 4.2.0 and WorkflowGen Server version 7.10.0 or later

Installation

Application registration

  1. Create an application on the https://apps.dev.microsoft.com/ site (such as WorkflowGen).

  2. In Application Secret section, generate a new password and save the secret.

  3. In Platforms section, click Add platform and choose Web.

  4. Check Allow implicit Flow and add https://login.microsoftonline.com to the Redirect URLs.

  5. Each workflow application requires specific permissions, so select these in Application Permissions, then save the application.

  6. To activate permissions, go to the URL https://login.microsoftonline.com/YOUR_TENANT_ID/adminconsent?client_id=YOUR_CLIENT_ID&redirect_uri=https://login.microsoftonline.com (replacing YOUR_TENANT_ID and YOUR_CLIENT_ID with your tenant and client IDs, respectively), and connect using an Administrator account.

Libraries installation on the WorkflowGen Server

The following components will be installed in the WorkflowGen \bin folders (\wfgen\bin, \wfgen\ws\bin, ..\Program Files\Advantys\WorkflowGen\Service\bin):

  • Advantys.Workflow.Applications.MicrosoftGraph.dll

  • Microsoft.Graph.dll

  • Microsoft.Graph.Core.dll

  • Microsoft.Identity.Client.dll

Quick Start

  1. Download the last release pack to your WorkflowGen server.

  2. Edit the config.json file, replacing WebAppPath and ServiceAppPath with your own paths (the default values are already specified).

  3. Execute the Install.ps1 script in PowerShell.

Custom installation

  1. Clone the repository.

  2. Open the WorkflowGenMicrosoftGraph.sln Visual Studio solution.

  3. Compile the solution and copy the generated Advantys.Workflow.Applications.MicrosoftGraph.dll file to the src/Install folder.

  4. Edit the config.json, replacing WebAppPath and ServiceAppPath with your own paths (the default values are already specified).

  5. Execute the Install.ps1 script in PowerShell.

WorkflowGen configuration

Add the following settings to the WorkflowGen \wfgen\web.config with your own values:

<add key="MicrosoftGraphTenant" value="TENANT_ID" />
<add key="MicrosoftGraphClientId" value="CLIENT_ID" />
<add key="MicrosoftGraphClientSecret" value="CLIENT_SECRET" />
<add key="MicrosoftGraphServiceAccountId" value="SERVICE_ACCOUNT_ID" />
<add key="MicrosoftGraphServiceLogPath" value="LOG_PATH" />

  • TENANT_ID: Your tenant ID, which you can find in Azure AD (Directory ID).

  • CLIENT_ID: The application ID you created earlier.

  • CLIENT_SECRET: The secret password you generated earlier.

  • SERVICE_ACCOUNT_ID: Your service account ID, which you can find in the Azure AD account profile (object id).
