LOB Integration webpart

This web part allows you to learn how to consume 3rd party APIs, secured with Azure Active Directory, in the context of SharePoint Framework. It leverages two different back-end REST APIs:

• An ApiController built in Microsoft ASP.NET MVC, which is defined in a .NET solution that you can find here
• An Azure Function, which is based on the code defined here

The purpose of this web part is to show how you can consume LOB (Line of Business) solutions and on-premises data within SharePoint Framework. In order to leverage this web part, you will need to configure a couple of applications in Azure Active Directory of your target tenant:

• SPFx-LOB-WebAPI: for the .NET web application
  • Publish the ASP.NET MVC application on an Azure App Service
  • Register the AAD app providing the URL of the above Azure App Service
  • Choose a valid App ID Uri for the app
  • Configure that App ID Uri in the LobIntegration.tsx React component
  • Update the App manifest of the Azure AD app configuring the oauth2Permissions property with a value like the following one:

  "oauth2Permissions": [
    {
      "adminConsentDescription": "Allow the application to read customers through SPFx-LOB-WebAPI on behalf of the signed-in user.",
      "adminConsentDisplayName": "Read customers from SPFx-LOB-WebAPI",
      "id": "7510eb34-4403-44d5-a745-a62d0895351c",
      "isEnabled": true,
      "type": "User",
      "userConsentDescription": "Allow the application to access SPFx-LOB-WebAPI on your behalf.",
      "userConsentDisplayName": "Access SPFx-LOB-WebAPI",
      "value": "Customers.Read"
    }
  ],

• SPFx-LOB-Function: for the Azure Function
  • Create an Azure Function and configure it with Azure AD Authentication, registering it in your target AAD tenant
  • Register the AAD app providing the URL of the above Azure Function
  • Choose a valid App ID Uri for the app
  • Configure that App ID Uri in the LobIntegration.tsx React component

Moreover, in order to make this web part working properly, you need to grant permissions to the SharePoint Service Application Principal to access them. You can do that using the PnP PowerShell command lets (or Office 365 CLI) with the following syntax:

Connect-PnPOnline "https://[your-tenant].sharepoint.com/"

Grant-PnPTenantServicePrincipalPermission -Resource "SPFx-LOB-WebAPI" -Scope "Customers.Read"
Grant-PnPTenantServicePrincipalPermission -Resource "SPFx-LOB-Function" -Scope "user_impersonation"
