This is a .Net SDK for ID Analyzer Identity Verification APIs, though all the APIs can be called with without the SDK using simple HTTP requests as outlined in the documentation, you can use this SDK to accelerate server-side development.
We strongly discourage users to connect to ID Analyzer API endpoint directly from client-side applications that will be distributed to end user, such as mobile app, or in-browser JavaScript. Your API key could be easily compromised, and if you are storing your customer's information inside Vault they could use your API key to fetch all your user details. Therefore, the best practice is always to implement a client side connection to your server, and call our APIs from the server-side.

ID Analyzer Core API allows you to perform OCR data extraction, facial biometric verification, identity verification, age verification, document cropping, document authentication (fake ID check), and paperwork automation using an ID image (JPG, PNG, PDF accepted) and user selfie photo or video. Core API has great global coverage, supporting over 98% of the passports, driver licenses and identification cards currently being circulated around the world.
The sample code below will extract data from this sample Driver License issued in California, compare it with a photo of Lena, and check whether the ID is real or fake.
try {
CoreAPI coreapi = new CoreAPI(API_KEY, API_REGION);
// Throw exception if API returns error
coreapi.ThrowAPIException(true);
// Enable authentication and use 'quick' module to check if ID is authentic
coreapi.EnableAuthentication(true, "quick");
// Send document to Core API and get json response
JObject result = await coreapi.Scan("https://www.idanalyzer.com/img/sampleid1.jpg", "", "https://upload.wikimedia.org/wikipedia/en/7/7d/Lenna_%28test_image%29.png");
// Print document holder name
Console.WriteLine(String.Format("Hello your name is {0} {1}", (string)result.SelectToken("result.firstName"), (string)result.SelectToken("result.lastName")));
// Parse document authentication results
if (result.ContainsKey("authentication")){
if ((double)result.SelectToken("authentication.score") > 0.5) {
Console.WriteLine("The document uploaded is authentic");
}else if ((double)result.SelectToken("authentication.score") > 0.3){
Console.WriteLine("The document uploaded looks little bit suspicious");
}else
{
Console.WriteLine("The document uploaded is fake");
}
}
// Parse face verification results
if (result.ContainsKey("face")){
if (result.SelectToken("face.error") != null){
// View complete error codes under API reference: https://developer.idanalyzer.com/coreapi.html
Console.WriteLine(String.Format("Face verification failed! Code: {0}, Reason: {1}", (string)result.SelectToken("face.error"), (string)result.SelectToken("face.error_message")));
}else
{
if ((bool)result.SelectToken("face.isIdentical") == true){
Console.WriteLine("Great! Your photo looks identical to the photo on document");
}else
{
Console.WriteLine("Oh no! Your photo looks different to the photo on document");
}
Console.WriteLine(String.Format("Similarity score: {0}", (string)result.SelectToken("face.confidence")));
}
}
// Print result
Console.WriteLine(Environment.NewLine + "Raw JSON Result: ");
Console.WriteLine(result.ToString());
}catch(APIException e)
{
Console.WriteLine("Error Code: " + e.ErrorCode);
Console.WriteLine("Error Message: " + e.Message);
}
catch (ArgumentException e)
{
Console.WriteLine("Input Error: " + e.Message);
}
catch (Exception e)
{
Console.WriteLine("Unexpected Error: " + e.Message);
}You could also set additional parameters before performing ID scan:
coreapi.EnableVault(true, false, false, false); // enable vault cloud storage to store document information and image
coreapi.SetBiometricThreshold(0.6); // make face verification more strict
coreapi.EnableAuthentication(true, "quick"); // check if document is real using 'quick' module
coreapi.EnableBarcodeMode(false); // disable OCR and scan for AAMVA barcodes only
coreapi.EnableImageOutput(true, true, "url"); // output cropped document and face region in URL format
coreapi.EnableDualsideCheck(true); // check if data on front and back of ID matches
coreapi.SetVaultData("user@example.com", "12345" , "AABBCC"); // store custom data into vault
coreapi.RestrictCountry("US,CA,AU"); // accept documents from United States, Canada and Australia
coreapi.RestrictState("CA,TX,WA"); // accept documents from california, texas and washington
coreapi.RestrictType("DI"); // accept only driver license and identification card
coreapi.SetOCRImageResize(0); // disable OCR resizing
coreapi.VerifyExpiry(true); // check document expiry
coreapi.VerifyAge("18-120"); // check if person is above 18

coreapi.VerifyName("Elon Musk"); // check if the person is named Elon Musk
coreapi.VerifyAddress("123 Sunny Rd, California"); // Check if address on ID matches with provided address
coreapi.VerifyPostcode("90001"); // check if postcode on ID matches with provided postcode
coreapi.EnableAMLCheck(true); // enable AML/PEP compliance check
coreapi.SetAMLDatabase("global_politicians,eu_meps,eu_cors"); // limit AML check to only PEPs
coreapi.EnableAMLStrictMatch(true); // make AML matching more strict to prevent false positives
coreapi.GenerateContract("Template ID", "PDF", new Hashtable { ["somevariable"] = "somevalue" }); // generate a PDF document autofilled with data from user IDTo scan both front and back of ID:
JObject result = await coreapi.Scan("path/to/id_front.jpg", "path/to/id_back.jpg");To perform biometric photo verification:
JObject result = await coreapi.Scan("path/to/id.jpg", "", "path/to/face.jpg");To perform biometric video verification:
JObject result = await coreapi.Scan("path/to/id.jpg", "", "", "path/to/video.mp4", "1234");Check out sample response array fields visit Core API reference.
DocuPass allows you to verify your users without designing your own web page or mobile UI. A unique DocuPass URL can be generated for each of your users and your users can verify their own identity by simply opening the URL in their browser. DocuPass URLs can be directly opened using any browser, you can also embed the URL inside an iframe on your website, or within a WebView inside your iOS/Android/Cordova mobile app.
DocuPass comes with 4 modules and you need to choose an appropriate DocuPass module for integration.
To start, we will assume you are trying to verify one of your user that has an ID of "5678" in your own database, we need to generate a DocuPass verification request for this user. A unique DocuPass reference code and URL will be generated.
try {
DocuPass docupass = new DocuPass(API_KEY, "My Company Inc.", API_REGION);
// Throw exception if API returns error
docupass.ThrowAPIException(true);
// We need to set an identifier so that we know internally who we are verifying, this string will be returned in the callback. You can use your own user/customer id.
docupass.SetCustomID(textBox7.Text);
// Enable vault cloud storage to store verification results, so we can look up the results
docupass.EnableVault(true);
// Set a callback URL where verification results will be sent, you can use docupass_callback.php in demo folder as a template
docupass.SetCallbackURL("https://www.your-website.com/docupass_callback.php");
// We want DocuPass to return document image and user face image in URL format so we can store them on our own server later.
docupass.SetCallbackImage(true, true, 1);
// We will do a quick check on whether user have uploaded a fake ID
docupass.EnableAuthentication(true, "quick", 0.3);
// Enable photo facial biometric verification with threshold of 0.5
docupass.EnableFaceVerification(true, 1, 0.5);
// Users will have only 1 attempt at verification
docupass.SetMaxAttempt(1);
// We want to redirect user back to your website when they are done with verification
docupass.SetRedirectionURL("https://www.your-website.com/verification_succeeded.php", "https://www.your-website.com/verification_failed.php");
// Create a DocuPass Mobile Session
JObject result = await docupass.CreateMobile();
// JObjectresult = await docupass.CreateLiveMobile();
Console.WriteLine("Scan the QR Code below to verify your identity: ");
Console.WriteLine((string)result["qrcode"]);
Console.WriteLine("Or open your mobile browser and type in: ");
Console.WriteLine((string)result["url"]);
//JObject result = await docupass.CreateIframe();
//Console.WriteLine("Embed following URL on your website: ");
//Console.WriteLine((string)result["url"]);
//JObject result = await docupass.CreateRedirection();
//Console.WriteLine("Redirect your user to the following URL: ");
//Console.WriteLine((string)result["url"]);
Console.WriteLine(Environment.NewLine+"Raw JSON Result: ");
Console.WriteLine(result.ToString());
}
catch (APIException e)
{
Console.WriteLine("Error Code: " + e.ErrorCode);
Console.WriteLine("Error Message: " + e.Message);
}
catch (ArgumentException e)
{
Console.WriteLine("Input Error: " + e.Message);
}
catch (Exception e)
{
Console.WriteLine("Unexpected Error: " + e.Message);
}If you are looking to embed DocuPass into your mobile application, simply embed result['url'] inside a WebView. To tell if verification has been completed monitor the WebView URL and check if it matches the URLs set in setRedirectionURL. (DocuPass Live Mobile currently cannot be embedded into native iOS App due to OS restrictions, you will need to open it with Safari)
Check out additional DocuPass settings:
docupass.SetReusable(true); // allow DocuPass URL/QR Code to be used by multiple users
docupass.SetLanguage("en"); // override auto language detection
docupass.SetQRCodeFormat("000000", "FFFFFF", 5, 1); // generate a QR code using custom colors and size
docupass.SetWelcomeMessage("We need to verify your driver license before you make a rental booking with our company."); // Display your own greeting message
docupass.SetLogo("https://www.your-website.com/logo.png"); // change default logo to your own
docupass.HideBrandingLogo(true); // hide footer logo
docupass.RestrictCountry("US,CA,AU"); // accept documents from United States, Canada and Australia
docupass.RestrictState("CA,TX,WA"); // accept documents from california, texas and washington
docupass.RestrictType("DI"); // accept only driver license and identification card
docupass.VerifyExpiry(true); // check document expiry
docupass.VerifyAge("18-120"); // check if person is above 18
docupass.VerifyDOB("1990/01/01"); // check if person's birthday is 1990/01/01
docupass.VerifyDocumentNumber("X1234567"); // check if the person's ID number is X1234567
docupass.VerifyName("Elon Musk"); // check if the person is named Elon Musk
docupass.VerifyAddress("123 Sunny Rd, California"); // Check if address on ID matches with provided address
docupass.VerifyPostcode("90001"); // check if postcode on ID matches with provided postcode
docupass.SetCustomHTML("https://www.yourwebsite.com/docupass_template.html"); // use your own HTML/CSS for DocuPass page
docupass.SMSVerificationLink("+1333444555"); // Send verification link to user's mobile phone
docupass.EnablePhoneVerification(true); // get user to input their own phone number for verification
docupass.VerifyPhone("+1333444555"); // verify user's phone number you already have in your database
docupass.EnableAMLCheck(true); // enable AML/PEP compliance check
docupass.SetAMLDatabase("global_politicians,eu_meps,eu_cors"); // limit AML check to only PEPs
docupass.EnableAMLStrictMatch(true); // make AML matching more strict to prevent false positives
docupass.GenerateContract("Template ID", "PDF", new Hashtable { ["somevariable"] = "somevalue" }); // automate paperwork by generating a document autofilled with ID data
docupass.SignContract("Template ID", "PDF", new Hashtable { ["somevariable"] = "somevalue" }); // get user to review and sign legal document prefilled with ID dataNow you should write a callback script or a webhook, to receive the verification results. Visit DocuPass Callback reference to check out the full payload returned by DocuPass. Callback script is generally programmed in a server environment and is beyond the scope of this guide, you can check out our PHP SDK for creating a callback script in PHP.
For the final step, you could create two web pages (URLS set via set_redirection_url) that display the results to your user. DocuPass reference will be passed as a GET parameter when users are redirected, for example: https://www.your-website.com/verification_succeeded.php?reference=XXXXXXXXX, you could use the reference code to fetch the results from your database. P.S. We will always send callbacks to your server before redirecting your user to the set URL.
You can get user to review and remotely sign legal document in DocuPass without identity verification, to do so you need to create a DocuPass Signature session.
DocuPass docupass = new DocuPass(API_KEY, "My Company Inc.", API_REGION);
// Throw exception if API returns error
docupass.ThrowAPIException(true);
// We need to set an identifier so that we know internally who is signing the document, this string will be returned in the callback. You can use your own user/customer id.
docupass.SetCustomID("123");
// Enable vault cloud storage to store signed document
docupass.EnableVault(true);
// Set a callback URL where signed document will be sent, you can use docupass_callback.php under this folder as a template to receive the result
docupass.SetCallbackURL("https://www.your-website.com/docupass_callback.php");
// We want to redirect user back to your website when they are done with document signing, there will be no fail URL unlike identity verification
docupass.SetRedirectionURL("https://www.your-website.com/verification_succeeded.php");
/*
docupass.SetReusable(true); // allow DocuPass URL/QR Code to be used by multiple users

// Create and get template ID under web portal
string template_id = "Your Template ID";
// Assuming in your contract template you have a dynamic field %{email} and you want to fill it with user email
Hashtable prefill = new Hashtable
{
["email"] = "user@example.com"
};
JObject result = await docupass.CreateSignature(template_id, "PDF", prefill);
Console.WriteLine("Scan the QR Code below to sign document:");
Console.WriteLine((string)result["qrcode"]);
Console.WriteLine("Or open your browser and navigate to: ");
Console.WriteLine((string)result["url"]);Once user has reviewed and signed the document, the signed document will be sent back to your server using callback under the contract.document_url field, the contract will also be saved to vault if you have enabled vault.
ID Analyzer provides free cloud database storage (Vault) for you to store data obtained through Core API and DocuPass. You can set whether you want to store your user data into Vault through enableVault while making an API request with PHP SDK. Data stored in Vault can be looked up through Web Portal or via Vault API.
If you have enabled Vault, Core API and DocuPass will both return a vault entry identifier string called vaultid, you can use the identifier to look up your user data:
try
{
Vault vault = new Vault(API_KEY, API_REGION);
// Throw exception if API returns error
vault.ThrowAPIException(true);
JObject result = await vault.Get("Vault ID");
Console.WriteLine(result.ToString());
}
catch (APIException e)
{
Console.WriteLine("Error Code: " + e.ErrorCode);
Console.WriteLine("Error Message: " + e.Message);
}
catch (ArgumentException e)
{
Console.WriteLine("Input Error: " + e.Message);
}
catch (Exception e)
{
Console.WriteLine("Unexpected Error: " + e.Message);
}You can also list the items in your vault, the following example list 5 items created on or after 2021/02/25, sorted by first name in ascending order, starting from first item:
string[] filter = { "createtime>=2021/02/25" };
JObject result = await vault.List(filter, "createtime", "ASC", 5, 0);Alternatively, you may have a DocuPass reference code which you want to search through vault to check whether user has completed identity verification:
string[] filter = { "docupass_reference=XXXXXXXXXXXX" };
JObject result = await vault.List(filter);Learn more about Vault API.
ID Analyzer provides Anti-Money Laundering AML database consolidated from worldwide authorities, AML API allows our subscribers to lookup the database using either a name or document number. It allows you to instantly check if a person or company is listed under any kind of sanction, criminal record or is a politically exposed person(PEP), as part of your AML compliance KYC. You may also use automated check built within Core API and DocuPass.
try
{
AMLAPI aml = new AMLAPI(API_KEY, API_REGION);
aml.ThrowAPIException(true);
JObject result = await aml.SearchByName("Joe Biden");
Console.WriteLine(result.ToString(Newtonsoft.Json.Formatting.Indented));
}

The API server may return error responses such as when document cannot be recognized. You can either manually inspect the response returned by API, or you may set ThrowAPIException(true); to raise an APIException when API error is encountered. You can then use try/catch block on functions that calls the API such as Scan, CreateMobile, CreateLiveMobile, CreateIframe, CreateRedirection, and all the functions for Vault to catch the errors. InvalidArgumentException is thrown when you pass incorrect arguments to any of the functions.
