This sample code provides guidance on how to use the Custom Translator API using ASP.NET MVC application. Refer to Custom Translator documentation to know more about different features of Custom Translator.

Custom Translator API documentation can be found here.

Please contact custommt@microsoft.com for questions and support.

This sample code uses OAuth and OpenID for authentication. Please sign in to https://apps.dev.microsoft.com with the same user credentials you use to login to Custom Translator. The landing page shows the list of client apps that are created/ available to use with your account.

Create an app using Add an app button at top right-hand corner of the landing page.

Enter application name and click on Create.

Generate a new password and keep it safe. This is the Application Secret, and will be used in the application for authentication.

When an application is created, the default delegated permission for it are User.Read. Add two additional delegated permissions

• offline_access
• openid.

Go to Microsoft Graph Permissions, the Delegated Permissions in the page to add these permissions.

For the MVC web application, a new “Web” platform needs to be added from “Platforms” section of the page.

Enter the Redirect URLs for the web platform. This URL is where your MVC web app should redirect after authentication. You can change Redirect URLs based on your application configuration.

Now save the changes you made and the portal will take you to the landing page, where all your registered applications are listed. The App Id/ Client ID listed here will be used to authenticate in the MVC web app.

If you haven't already logged in to Custom Translator Portal with your user account (the same user account you used to create/register the AAD app), you will need to login to accept the terms and conditions.

After you sign in to Custom Translator portal with your user account, you will receive a popup window requesting your consent.

After you’ve provided consent, a popup window for terms will be shown. Read and accept the terms to continue.
