Data Extraction
Note: Please ensure that you have completed the Get Started section before diving into and attempting to make use of any of the below features.
The web SDK provides two different ways of integrating identity data extraction functionality into your project.
You can either use our pre-built components which can be configured and styled for your needs, or you can completely build the UI yourself and make use of our JavaScript API to integrate with our data extraction functionality.
Components
The following components are available:
It is recommended that you use the wizard component, which encapsulates and orchestrates the other components in a flow. It can be set up using configuration options relevant to your use case. You may also use each component separately if you choose.
Country Select Component
This component can be found under the Sybrin.Identity
namespace and is called CountrySelectComponent
.
Full name: Sybrin.Identity.CountrySelectComponent
.
It is a component that provides basic country selection functionality in the form of a simple UI. The Web SDK requires a country code for data extraction and it's recommended that you use this component to obtain said country code.
With default styling, the country select component appears as follows:
Upon selecting a country, the onCountrySelected
event will fire, passing the selected country code as a string parameter.
Initialization
The country select component can be initialized using the following code:
The Sybrin Web SDK provides the option to either pass down the ID of the element you wish to use for component initialization, or to pass the element directly.
Please note that 'country-select' is just an example in this context and the ID may be changed as desired as long as it matches the value passed down during component initialization in JavaScript.
During initialization, the country select component allows for a number of configuration options that may be passed down using an object literal. The parameters that may be used on the object include the following:
Required:
id (string)
: ID of the element you wish to use for component initialization. Not required ifelement
is passed.element (HTMLElement)
: Element you wish to use for component initialization. Not required ifid
is passed.
Optional:
documentTypeName (string)
: The document type name to filter country selection by. If a document type name is passed down, only countries that support the specified document type will be shown. Please see document type overrides & filtering for a list of accepted values.countries (Sybrin.Identity.Country[])
: Explicit country filter. Please see country overrides & filtering for details.
For altering component text or implementing localization if required:
headingText (string)
: Text to display in the heading. Default "Country select"subtitleText (string)
: Text to display in the subtitle. Default "Select your country"companyText (string)
: Company text to display at the foot of the component. Default "Sybrin"
Warning: Initialization will fail if the intended host element does not exist yet.
Always ensure that the initialize function is only called after the DOM is loaded.
Country Overrides & Filtering
When creating an instance of the country select component, the SDK allows for a documentTypeName
string parameter, which will be used to filter countries based on the document type. Additionally, the SDK allows for a countries
parameter which can be used for more specific override options. The countries
parameter is a collection of Sybrin.Identity.Country
where each instance has the properties code
, name
and enabled
.
code (string)
: The unique identifier used to target a country to override.name (string)
: Can be used to override the display name of the targeted country.enabled (boolean)
: Can be used to filter out the targeted country (if set to false)
Supported country codes are:
Ghana:
'GHA'
Kenya:
'KEN'
Malawi:
'MWI'
Mozambique:
'MOZ'
South Africa:
'ZAF'
Uganda:
'UGA'
Zimbabwe:
'ZWE'
Advanced filtering and override example:
By specifying documentTypeName
as 'idcard'
, it will only show countries that support the ID Card document type. The first country instance in the countries collection overrides 'ZAF'
, which is South Africa, to display as Southern Africa instead. The second instance filters 'UGA'
, which is Uganda, out so that it doesn't appear as part of the list even though the Ugandan ID Card document type is supported.
Destruction
The country select component may be removed from the UI by calling the destroy()
function on it.
Example:
Events
The country select component offers one event for reacting to country selection. To hook onto the event, simply assign a function to it.
The following option is available:
onCountrySelected(countryCode: string)
On Country Selected
This function is called when a country is selected. To hook onto the event, you may use the following code:
The countryCode parameter is of type string
.
Styling
The country select component is structured a follows:
The classes and elements specified above may be used to freely style the country select component as desired. To do so, simply create a stylesheet and include it in the project, then style according to the above classes and elements.
The element with the sybrin-identity-card
class repeats for every country option.

Document Select Component
This component can be found under the Sybrin.Identity
namespace and is called DocumentSelectComponent
.
Full name: Sybrin.Identity.DocumentSelectComponent
.
It is a component that provides basic document selection functionality in the form of a simple UI. The Web SDK requires a document type for data extraction and it's recommended that you use this component to obtain said document type.
With default styling, the document select component appears as follows:
Upon selecting a document, the onDocumentSelected
event will fire, passing the selected document type as a string parameter.
Initialization
The document select component can be initialized using the following code:
The Sybrin Web SDK provides the option to either pass down the ID of the element you wish to use for component initialization, or to pass the element directly.
Please note that 'document-select' is just an example in this context and the ID may be changed as desired as long as it matches the value passed down during component initialization in JavaScript.
During initialization, the document select component allows for a number of configuration options that may be passed down using an object literal. The parameters that may be used on the object include the following:
Required:
id (string)
: ID of the element you wish to use for component initialization. Not required ifelement
is passed.element (HTMLElement)
: Element you wish to use for component initialization. Not required ifid
is passed.
Optional:
countryCode (string)
: The Alpha-3 standard country code to filter document selection by. If a country code is passed down, only documents supported by the specified country will be shown. Please see country overrides & filtering for a list of accepted values.documentTypes (Sybrin.Identity.DocumentType[])
: Explicit document type filter. Please see document type overrides & filtering for details.
For altering component text or implementing localization if required:
headingText (string)
: Text to display in the heading. Default "Country select"subtitleText (string)
: Text to display in the subtitle. Default "Select your country"companyText (string)
: Company text to display at the foot of the component. Default "Sybrin"
Document Type Overrides & Filtering
When creating an instance of the document select component, the SDK allows for an Alpha-3 standard countryCode
parameter, which will be used to filter document types based on the country. Additionally, the SDK allows for a documentTypes
parameter which can be used for more specific override options. The parameter is a collection of objects where each instance has the properties name
, title
, subtitle
and enabled
.
id (string)
: The unique identifier (document type ID) used to target a document type to override.title (string)
: Can be used to override the display title of the targeted document type.subtitle (string)
: Can be used to override the display subtitle of the targeted document typeenabled (boolean)
: Can be used to filter out the targeted document type (if set to false)frontThreshold (number)
: The confidence threshold value to use when running document detection on the front image. A lower value modifies detection to be more sensitive. A higher level makes it less sensitive, up to a maximum of 100.backThreshold (number)
: The confidence threshold value to use when running document detection on the back image if applicable. A lower value modifies detection to be more sensitive. A higher level makes it less sensitive, up to a maximum of 100.

JavaScript API
If you wish to use the functionality provided by the Sybrin Identity Web SDK but create your own UI entirely, you may achieve this by simply creating an instance of the JavaScript API and using the functions exposed by it.
Initialization
The JavaScript API may be initialized as follows:
The options object may be used to configure the API as desired.
Configuration Options
The following properties are exposed as configuration options:

Functionality
The Sybrin Identity Javascript API provides multiple ways of running data extraction on identity documents and other functions to control the Web SDK.
These include:
Extract Data Using Camera
Extract Data Using File Upload
Cancel
Additionally, the API provides:
Version Information Retrieval
Client Information Retrieval
Extract Data Using Camera
To use the camera for data extraction, you may make use of the openScanDocument
function exposed by the JavaScript API.
An argument, passed as an object literal, is required for this function call. The object literal must have these required properties:
documentTypeId (string)
: The ID that points to a unique document type for a specific country. Not required ifcountryCode
anddocumentTypeName
are specified.countryCode (string)
: The country that data extraction should run for. Not required ifdocumentTypeId
is specified.documentTypeName (string)
: The document type that data extraction should run for. Not required ifdocumentTypeId
is specified.
Optionally you may also specify the following properties:
id (string)
: The ID of the element to create the video feed in. Theelement
property takes precedence over theid
property.element (HTMLElement)
: The element to create the video feed in. Takes precedence over theid
property.correlationId (string)
: Value that is used to associate the result with a specific case.
If no id or element property is passed on the argument, the Web SDK will temporarily inject a full screen element to display the video feed.
The function returns a promise, so you may choose to use either the asynchronous await pattern or to subscribe to the result using .then()
, .catch()
and .finally()
.
Example:
Extract Data Using File Upload
To use a file upload for data extraction, you may make use of the uploadDocument
function exposed by the JavaScript API.
An argument, passed as an object literal, is required for this function call. The object literal must have these required properties:
documentTypeId (string)
: The ID that points to a unique document type for a specific country. Not required ifcountryCode
anddocumentTypeName
are specified.countryCode (string)
: The country that data extraction should run for. Not required ifdocumentTypeId
is specified.documentTypeName (string)
: The document type that data extraction should run for. Not required ifdocumentTypeId
is specified.
Optionally you may also specify the following properties:
frontFile (File)
: The front image file to run data extraction on.backFile (File)
: The back image file to run data extraction on.frontBase64 (string)
: A base64 string of the front image to run data extraction on.backBase64 (string)
: A base64 string of the back image to run data extraction on.correlationId (string)
: Value that is used to associate the result with a specific case.loaderContainer (HTMLElement)
: The HTML element to display a loader inside while processing.
The frontFile
, backFile
, frontBase64
and backBase64
properties offer an opportunity to implement your own method of obtaining files for upload. If none of these are passed, the Web SDK will invoke the default file explorer window provided by the browser to allow for front (as well as back, if required for the document type) file selection.
If you wish to provide the front file, only one parameter between frontFile
and frontBase64
is required.
If you wish to provide the back file where applicable, only one parameter between backFile
and backBase64
is required.
The function returns a promise, so you may choose to use either the asynchronous await pattern or to subscribe to the result using .then()
, .catch()
and .finally()
.
Example:
Cancel
A function to cancel any action that the identity Web SDK is currently executing. This is useful if you wish to add a cancel button to the UI so that the user may stop data extraction while it's in progress.
Example:
Version Information Retrieval
To get all version info regarding the Web SDK and its components, the API exposes a function called getVersionInfo
.
Usage example:
The result has the following properties:
webSdkVersion (string)
: The semantic version number of the JavaScript web SDK that is currently in use.
Client Information Retrieval
To get all version info regarding the client environment in which the application is currently running, the API exposes a function called getClientInfo
.
Usage example:
The result is of type ClientInfo
and has the following properties:
isMobile (boolean)
: Whether or not the client environment is mobile (tablet or phone).isMobileAndroid (boolean)
: Whether or not the client environment is running Android.isMobileBlackberry (boolean)
: Whether or not the client environment is running Blackberry.isIphone (boolean)
: Whether or not the client environment is running on an iPhone.isIpad (boolean)
: Whether or not the client environment is running on an iPad.isIpadPro (boolean)
: Whether or not the client environment is running on an iPad Pro.isIpod (boolean)
: Whether or not the client environment is running on iPod.isMobileIos (boolean)
: Whether or not the client environment is running iOS.isMobileOpera (boolean)
: Whether or not the client environment is mobile Opera.isMobileWindows (boolean)
: Whether or not the client environment is Windows Mobile.isMac (boolean)
: Whether or not the client environment is running on Mac.
Debug Information Download
Before using this function, please ensure that the recordDebugInfo
configuration option has been set.
This is for debug and diagnostic purposes only and can only be used once debug functionality has been configured. It can be used after a liveness scan to download an HTML file containing information relating to the scan attempt.
Usage example:
Debug Information Upload
Before using this function, please ensure that the recordDebugInfo
configuration option has been set.
This is for debug and diagnostic purposes only and can only be used once debug functionality has been configured. It can be used after a liveness scan to upload an HTML file containing information relating to the scan attempt. The file is uploaded to the endpoint configured in the debugInfoEndpoint
configuration option.
This function sends a POST message to the configured endpoint and the payload is a string on the form body, called debugInfo
.
IMPORTANT: The HTML file includes the selfie taken during the scan attempt. Please keep the POPI act in mind when making use of this feature. Sybrin accepts no responsibility for any breach of the POPI act should this function be used to upload data to your own custom hosted service.
