Welcome to the Yoti .NET SDK. This repo contains the tools and step by step instructions you need to quickly integrate your .NET back-end with Yoti so that your users can share their identity details with your application in a secure and trusted way.

An Architectural View

To integrate your application with Yoti, your back-end must expose a GET endpoint that Yoti will use to forward tokens. The endpoint can be configured in Yoti Hub when you create/update your application.

The image below shows how your application back-end and Yoti integrate in the context of a Login flow. Yoti SDK carries out for you steps 6, 7 ,8 and the profile decryption in step 9.

Yoti also allows you to enable user details verification from your mobile app by means of the Android (TBA) and iOS (TBA) SDKs. In that scenario, your Yoti-enabled mobile app is playing both the role of the browser and the Yoti app. By the way, your back-end doesn't need to handle these cases in a significantly different way. You might just decide to handle the User-Agent header in order to provide different responses for web and mobile clients.

Enabling the SDK

To install the Yoti NuGet package you will need to install NuGet. You can find instructions to do that here

To import the latest Yoti SDK into your project, enter the following command from NuGet Package Manager Console in Visual Studio:

Install-Package Yoti

For other installation methods, see nuget.org/packages/Yoti

Client Initialisation

The YotiClient is the SDK entry point. To initialise it you need include the following snippet inside your endpoint initialisation section:

const string sdkId = "your-sdk-id";
var privateKeyStream = System.IO.File.OpenText("path/to/your-application-pem-file.pem");
var yotiClient = new YotiClient(sdkId, privateKeyStream);


  • sdkId is the sdk identifier generated by Yoti Hub when you create (and then publish) your app. Note this is not your Application Identifier which is needed by your clientside code
  • path/to/your-application-pem-file.pem - When you create your app on Yoti Hub, your browser generates a .pem file. This is the path to that file.

You'll need to add the correct callback URL to one of the scenarios of your application from the "Applications" sections on Yoti Hub. You also need to make sure that the value of the data-yoti-scenario-id attribute in the Yoti button matches the id in the selected scenario.

Profile Retrieval

When your application receives a one time use token via the exposed endpoint (it will be assigned to a query string parameter named token), you can easily retrieve the user profile by adding the following to your endpoint handler:

var activityDetails = yotiClient.GetActivityDetails(oneTimeUseToken);

Or if you are in an asynchronous method:

var activityDetails = await yotiClient.GetActivityDetailsAsync(oneTimeUseToken);

Handling Users

The ActivityDetails includes a unique identifier for the user, named RememberMeId. You can use this to identify users returning to your application, but if the user completes a share with a different application, Yoti will assign a different RememberMeId. Applications registered to an organisation may also utilise an additional unique identifier named ParentRememberMeId. Use this to identify users returning to your organisation. It is consistent for a given user in all applications registered to a single organisation.
