Here is a quick start guide to accelerate your SDK integration. For detailed information, we suggest that you read through the step-by-step integration guide.
Install the SDK
Yoti SDKs are available for several languages through popular dependency management systems.
To install the SDK:
npm install -S -E yoti
// If you are using Maven, add the following dependency:
<dependency>
<groupId>com.yoti</groupId>
<artifactId>yoti-sdk-api</artifactId>
<version>4.0.0</version>
</dependency>
// If you are using Gradle, add the following dependency:
compile group: 'com.yoti', name: 'yoti-sdk-api', version: '4.0.0'
// Get the Yoti PHP SDK library via a Composer package
composer require yoti/yoti-php-sdk
// To install the Yoti NuGet package you will need to install NuGet.
// 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 https://www.nuget.org/packages/Yoti
// Simply add this as an import:
import "github.com/getyoti/yoti-go-sdk/v3"
// Or add the following line to your go.mod file
require github.com/getyoti/yoti-go-sdk/v3
// Or you can run the following command in your terminal:
go get github.com/getyoti/yoti-go-sdk/v3
Using Yoti SDKs
The description on how to use the above endpoint from the SDK can be found here:
Please read the above for a full description and understanding, below we have provided examples on how those requests will expose the new functionality.
First, specify the required imports and create a DocScanClient using the SDK ID and the PEM file. Then, define the subject to be returned in the verification report. And set the advanced identity profile requirements to your desired scheme. You will need to set up the SDK configuration and a session specification using the scheme requirements and the SDK config. Finally, use the DocScanClient to create a session by providing the session specification. Retrieve the Session ID and Client Session Token and utilise them to generate the iframe URL.

Client side view
Once you have generated the iframe URL, you can send it to the frontend for it to be rendered on the page. Please see example below:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Embedded IDV Integration</title>
</head>
<body>
<div>
<iframe style="border:none;" width="100%" height="750" allow="camera" src="<%= iframeUrl %>" allowfullscreen></iframe>
</div>
</body>
</html>
Retrieve Results
After a session has been created, you can use the Yoti SDK to retrieve the session result (containing all the end-user's uploaded documents and associated metadata).
Result of the session
Session retrieval requires a session ID. This is generated while creating a session as demonstrated above.
// Returns the session result
const sessionResult = await idvClient.getSession(sessionId);
// Returns the session state
const state = sessionResult.getState();
// Returns session resources
const resources = session.getResources();
// Returns the session result
GetSessionResult sessionResult = docScanClient.getSession(sessionId);
// Returns the session state
String state = sessionResult.getState();
// Returns session resources
ResourceContainer resources = sessionResult.getResources();
// Returns the session result
$sessionResult = $docScanClient->getSession($sessionId);
// Returns the session state
$state = $sessionResult->getState();
// Returns session resources
$resources = $sessionResult->getResources();
// Returns the session result
GetSessionResult sessionResult = docScanClient.GetSession(sessionId);
// Returns the session state
string state = sessionResult.State;
// Returns session resources
ResourceContainer resources = sessionResult.Resources;
// Returns a session result
sessionResult, err := client.GetSession(sessionId)
if err != nil {
return nil, err
}
// Returns the session state
state = sessionResult.State
// Returns session resources
resources = sessionResult.Resources
Retrieve Media
In order to retrieve document images and document fields from the resources container we have to look for the relevant media ID inside of the id document pages.
// Returns a collection of ID Documents
const idDocuments = resources.getIdDocuments();
const media = await idvClient.getMediaContent(sessionId, mediaId);
const buffer = media.getContent();
const base64Content = media.getBase64Content();
const mimeType = media.getMimeType();
// Returns a collection of ID Documents
List<? extends IdDocumentResourceResponse> idDocuments = resources.getIdDocuments();
Media media = docScanClient.getMediaContent(sessionId, mediaId);
// Returns a collection of ID Documents
$idDocuments = $resources->getIdDocuments();
$media = $docScanClient->getMediaContent($sessionId, $mediaId);
$base64Content = $media->getBase64Content();
$contentType = $media->getMimeType();
// Returns a collection of ID Documents
List<IdDocumentResourceResponse> idDocuments = resources.IdDocuments;
MediaValue media = docScanClient.GetMediaContent(sessionId, mediaId);
// Returns a collection of ID Documents
idDocuments = resources.IDDocuments
media, err := client.GetMediaContent(sessionId, mediaID)
mimeType = media.MIME()
data = media.Data()
Retrieve Identity Profile
Once the session has reached the state of 'Completed', identify profile can be successfully retrieved.
In case of a successful transaction, once the identity profile is received, the identity profile report JSON will be accessible. This contains the media ID which can then be used to get the full JSON response of the report.
const advancedIdentityProfile = sessionResult.getAdvancedIdentityProfile();
const report = advancedIdentityProfile.getIdentityProfileReport();
const mediaID = report.getMedia().getId();
const identityProfileReportMedia = await idvClient.getMediaContent(sessionId, mediaId);
const identityProfileReportMediaBuffer = identityProfileReportMedia.getContent();
String mediaID = sessionResult.getAdvancedIdentityProfile().getIdentityProfileReport().getMedia().getId();
Media identityProfileReportMedia = await docScanClient.getMediaContent(sessionId, mediaId);
$identityProfile = $sessionResult->getAdvancedIdentityProfile();
$identityProfileReport = $identityProfile->getIdentityProfileReport();
$mediaId = $identityProfileReport->media['id'];
$identityProfileReportMedia = $docScanClient->getMediaContent($sessionId, $mediaId);
$base64Content = $media->getBase64Content();
$contentType = $media->getMimeType();
string mediaId = sessionResult.AdvancedIdentityProfile.Report["media"]["id"].ToString();
MediaValue mediaValue = docScanClient.GetMediaContent(sessionId, mediaId);
byte[] identityProfileReport = mediaValue.GetContent();
identityProfile = sessionResult.AdvancedIdentityProfileResponse
identityProfileReport = identityProfile.IdentityProfileResponse.Report
media, err := identityProfile.Report["media"].(map[string]interface{})
mediaID, err := media["id"].(string)
identityProfileReportMedia, err := client.GetMediaContent(sessionId, mediaID)
