IDmission Web SDK

Storybook: https://websdk2test.idmission.com

Getting Started

Before using the IDmission WebSDK, you should make sure you can fetch a token. New customers receive their token generation credentials via email. If you haven't received them, reach out to support@idmission.com.

To test that your credentials are valid:

curl --location --request POST 'https://auth.idmission.com/auth/realms/identity/protocol/openid-connect/token' \
    --header 'Content-Type: application/x-www-form-urlencoded' \
    --data-urlencode 'grant_type=password' \
    --data-urlencode 'client_id=' \
    --data-urlencode 'client_secret=' \
    --data-urlencode 'username=' \
    --data-urlencode 'password=' \
    --data-urlencode 'scope=api_access'

Prior to initializing the WebSDK on the client, you should generate a token on your server using these credentials. Be careful not to leak them on the client side! The generated token is safe to pass to the client, but the secrets used to generate them are not. If you have inadvertently leaked your client secret, react out to support@idmission.com to rotate your credentials.

If you are using NodeJS, check out our auth client for server-side JavaScript.

Basic Usage in Typescript/React

npm i idmission-web-sdk

import React from 'react'
import { render } from 'react-dom'
import { IdValidation } from 'idmission-web-sdk'

render(<IdValidation submissionToken={YOUR_TOKEN} />, document.getElementById('root'))

Basic Usage in HTML

Add the following script tag to your page's <head>:

<script type="module" src="https://websdk-cdn-dev.idmission.com/websdk/prod/loader.js"></script>

You may subscribe to the idmission-web-sdk.ready event to be notified when loading has completed.

<script type="module">
    document.addEventListener('idmission-web-sdk.ready', () => {
      // this code fires when the sdk has finished loading.
    })
</script>

Then you may call any render method below, for example renderIdValidation, like so:

<script type="module">
    IDmissionSDK.renderIdValidation('#target-element', { submissionToken: 'my-idmission-token' });
</script>

Other Functionality

Detecting the current version of the IDmission Web SDK

If you're ever wondering which version you have loaded, you can access it as a property of the global WebSDK bundle via window.IDmissionSDK.version.

You can also capture this information from the event fired at load time via e.detail.webSdkVersion like so:

<script type="module">
    document.addEventListener('idmission-web-sdk.ready', (e) => {
      console.log('web sdk version:', e.detail.webSdkVersion)
    })
</script>

Preloading the models

If you would like to programmatically issue a command to begin downloading and preparing the models on the client's browser before they enter a customer flow, the following method is available:

<script type="module">
    document.addEventListener('idmission-web-sdk.ready', (e) => {
      IDmissionSDK.preloadModels()
    })
</script>

You may specify which models should be loaded and which should be skipped by supplying an object argument, like so:

IDmissionSDK.preloadModels({
  documentDetectionModel: true,
  focusModel: true,
  faceDetectionModel: false,
})

This can be useful if, for example, you know you won't need any flows that depend on face detection.

Intercepting (and modifying) API calls to IDmission's backend with `onBeforeSubmit`

Each customer flow documented above includes an optional onBeforeSubmit prop, which bears the type signature (request: SubmissionRequest) => Promise<SubmissionRequest>. This can be useful if you would like to include some custom functionality that interrupts the WebSDK's outgoing request to IDmission's servers, allowing you a chance to modify the request before it is dispatched.

To delay the submission until some async condition has been met by your application:

onBeforeSubmit: () => new Promise((resolve) => {
  // do whatever you want in here, websdk will delay submission until you call:
  resolve()
})

Calling resolve() without an argument as shown above will result in no modification being made to the request that will be sent to IDmission's servers.

To alter the submission request before it goes out:

onBeforeSubmit: (req) => new Promise((resolve) => {
  req.myRandomExtraThing = '123'
  resolve(req)
})

Note that you will receive the request as a parameter to onBeforeSubmit, and must resolve with the altered version in order for your changes to be committed.

If the promise is rejected or an error is thrown, that rejection value or error will be printed to the logs and the request will be not be sent. The onRequestFailure hook will be fired with the error that came from your code.

Providing multi-language verbiage overrides

Each customer flow documented above includes an optional verbiage prop, bearing the type signature { [key: string]: CustomerSuppliedVerbiage }. The CustomerSuppliedVerbiage can be a string (which overrides all locales), or a { [key: string]: string } containing verbiage overrides in multiple i18n locales.

The level of specificity in locale codes can be controlled by supplying or omitting suffixes, for example, en-UK would target only systems configured for British English, which en would target all English-speaking locales. Specifying both would show your en-UK translation for British users and your en translation for everyone else.

For example, if we want to override the header text on the loading overlay of the FaceValidation flow:

verbiage: {
  loadingOverlay: {
    headerText: {
      'en-US': 'Use your device camera to capture your American face',
      'en-UK': 'Use your device camera to capture your British face',
      'en': 'Use your device camera to capture your generally English-speaking face'
    }
  }
}

Leaving a locale out of your translation object will result in the default text being shown for that locale, with the rest of your provided translations being honored. This functionality can be leveraged to define translations for languages that the IDmission Web SDK does not yet support. If you end up creating full translations for new languages, feel free to send your translations our way at https://www.idmission.com/company/contact-us/, and we will try to get them added to the main SDK translation set!
