Overview

This SDK provides a set of components for JavaScript applications to allow capturing of identity documents (by file upload or capture by camera) for the purpose of identity verification. The SDK offers a number of benefits to help you create the best onboarding / identity verification experience for your customers:

- Configurable UI to help you to set SDK looks according your current app theme
- Carefully designed UI to guide your customers through the entire photo-capturing process
- Direct image upload to the DataFornix service, to simplify integration*

Note: the SDK is only responsible for capturing photos. You still need to access the DataFornix API to manage applicants and checks.

Users will be prompted to upload a file containing an image of their document. On handheld devices they can also use the native camera to take a photo of their document.

Getting started

$3

In order to start integration, you will need the SDK token.

$3

#### 2.1 HTML Script Tag Include

Include it as a regular script tag on your page:

``html

`

#### 2.2 NPM style import

You can also import it as a module into your own JS build system (tested with Webpack).


`sh
$ npm install --save data-fornix-web-dc
`

`js
// ES6 module import
import DataFornixDC from 'data-fornix-web-dc'

// commonjs style require
var DataFornixDC = require('data-fornix-web-dc')
`

#### Notice

The library is Browser only, it does not support the Node Context.

$3

There is only one element required in your HTML, an empty element for the modal interface to mount itself on:

`html




`

$3

You are now ready to initialise the SDK:

`js
// Create instance of DataFornix Document Capture SDK
// and store it in dataFornixWeb for future use
const dataFornixWeb = new DataFornixDC({
// the SDK token
token: 'YOUR_SDK_TOKEN',
// id of the element you want to mount the component on
containerId: 'data-fornix',
onComplete: function (data) {
// onComplete function that return you uploaded documents
// you can get uploaded documents in data.frontFile
// and data.backFile if capturing document back
}
});
`

Congratulations! You have successfully started the flow. Carry on reading the next sections to learn how to:

- Handle callbacks
- Remove SDK previous state (if using single page application)
- Customise the SDK UI and use other usefull configuration

Handling callbacks

- onComplete {Function}

onComplete callback that fires when the document successfully been uploaded.
At this point you can use DataFornix API SDK to capture data from documents. DataFornix API SDK.
The onComplete returns uploaded documents object. The data will be formatted as follow:
{frontFile: FILE_OBJECT, backFile: FILE_OBJECT}.

Here is an onComplete example:

`js
const dataFornixWeb = new DataFornixDC({
token: 'YOUR_SDK_TOKEN',
containerId: 'data-fornix',
onComplete: documentCaptureCallback
});

function documentCaptureCallback(data) {
const capturedDocument = {
'front_image': data.frontFile,
'back_image': data.backFile
};
}
`

Removing SDK

If you are embedding the SDK inside a single page app, you can call the clearState function to remove the SDK complelety from the current webpage. It will reset state and you can safely re-initialise the SDK inside the same webpage later on.

`javascript
const dataFornixWeb = new DataFornixDC({...})
...
dataFornixWeb.clearState()
`

Customising SDK

A number of options are available to allow you to customise the SDK UI:

- token {String} required

A SDK Token is required in order to authorise. If one isn’t present, an exception will be thrown.

- containerId {String} optional

A string of the ID of the container element that the UI will mount to. This needs to be an empty element. The default ID is root.

- documentBackCapture {Boolean} optional

Provide option to upload document both side (front and back) upload. The default ID is false.

- baseUrl {String} optional

Server baseUrl which is use by sdk from internal api call. If not pass then sdk will use default url that set in sdk config.

- uiOptions {Object} optional
You can updated UI of SDK according your current app theme. It has following options:-

Name | Type | Default | Description |
--- | --- | --- | --- |
isDraggabel | Boolean | true | Show file drag/drop option |
dragAreaWidth | Number | 160 | Set drag area width
dragAreaHight | Number | 125 | Set drag area hight
documentPreview | Boolean | true | Show document preview in drag area
useCamera | Boolean | true | Show option for capture image using native camera
firstInputTitle | String | Front of Document | Set title of first input
firstInputPlaceholder | String | Drag file here.. | Set placehoder for first input
secondInputTitle | String | Back of Document | Set title of second input
secondInputPlaceholder | String | Drag file here.. | Set placehoder for second input
borderColor | String | #949494 | Set border color |
fontSize | String | inherit | Set font size |
fontFamily | String | inherit | Set font family |
fontColor | String | inherit | Set font color |
backgroundColor | String | transparent | Set background color |

Example to use uiOptions
`javascript
const dataFornixWeb = new DataFornixDC({
token: 'YOUR_SDK_TOKEN',
containerId: 'data-fornix',
onComplete: documentCaptureCallback,
uiOptions: {
// drag options
isDraggabel: true,
dragAreaHight: 125,
dragAreaWidth: 250,
documentPreview: true,

//input options
firstInputTitle: 'Front of Licence',
firstInputPlaceholder: 'Drag front of licence..',
secondInputTitle: 'Back of Licence',
secondInputPlaceholder: 'Drag back of licence..',

//UI options
borderColor: '#ccc',
fontSize: 14,
fontFamily: 'Raleway',
buttonPrimaryColor: '#4CAF50',
fontColor: '#333'
}
});
