General

This document explains how to integrate the verification flow directly from your React application through our Javascript component to verify the identity of your users. This stage might be at the signup page of your application, or at a later point to enrich the profiles of your users. The guide assumes the preliminary steps have already been completed as explained in the initial setup section of the documentation.

We suggest you follow our best practice how to integrate Passbase in your wider system in the overview section.

You can either follow the integration guide below or also watch the video below that shows an integration. Please be aware that some property or function names might have slightly changed. Just compare to the latest code snippets here in the documentation.

​

1. Install the Package

Start by installing our component and its dependencies in your React project:

$ npm i --save @passbase/button@3.0.0

$ yarn add @passbase/button@v3

2. Render the Component

Import the React component from the newly installed npm package. The package supports UMD modules, the ES import method is presented below.

src/App.js
import VerifyButton from "@passbase/button/react";

In order for the button to render correctly, you'll need to pass your previously generated apiKey as argument to the rendering function. Optionally you can also pass in handler functions like onFinish, onStart and onError to control the states of the button flow.

src/App.js
function App() {
  return (
    <div className="App">
      <VerifyButton
        apiKey={"YOUR_API_KEY"}
        onFinish={(identityAccessKey) => {}}
        onError={(errorCode) => {}}
        onStart={() => {}}
      />;
    </div>
  );
}

The button should now render as shown here:

Speed Up the Verification Flow

During the verification flow, your users will be asked to provide some information which you might already have in your application e.g. the user's email. In this case, you can use the prefillAttributes object to skip the email step.

<VerifyButton
  apiKey={"YOUR_API_KEY"}
  onFinish={(identityAccessKey) => {}}
  prefillAttributes={{
    email: "user@email.de",
    country: "de"
  }}
/>

Reference Your Users

In order for your application to interoperate with Passbase, you need to add a reference to your users once the Verification is completed.

For that, you need to keep track of the identityAccessKey returned by the onFinish callback and associate it in your backend with your users' id. We recommend to either save this key after the onFinish method to your user's model, or listen for incoming webhooks and then link back the user via their email.

import React from 'react';
import VerifyButton from "@passbase/button/react";
​
function App() {
  const referenceUserWithKey = (key) => {
    console.log(key)
    // Make request to your backend/db and save the key to the user's profile
  }
​
  return (
    <div className="App">
      <VerifyButton
        apiKey={"YOUR_PUBLISHABLE_API_KEY"}
        onFinish={(identityAccessKey) => {
          referenceUserWithKey(identityAccessKey)
        }}
        onError={(errorCode) => {}}
        onStart={() => {}}
        prefillAttributes={{
          email: "hans.meier@corp.de"
        }}
      />
    </div>
  );
}
​
export default App;

3. UI Customizations

Appearance

Our component currently supports a set of customization options which will influence the appearance of the modal, once opened. The preferred way to customize this is via your developer dashboard's customization section.

Here you can choose amongst a variety of colors, fonts, accepted countries & much more.

The modal also supports a darkMode attribute, which supersedes the effects of any customization selected within the developer dashboard. This is especially useful if your App has a dark UI or you simply want to spare your users' eyes at night. You can activate the darkmode via the theme attribute.

<VerifyButton
  apiKey={"YOUR_API_KEY"}
  onFinish={(identityAccessKey) => {}}
  theme={{
      darkMode: true,
      systemDarkMode: true
  }}
/>;

Language

We support a variety of different languages for the verification flow. As of this writing more than 10 including (English, Spanish, German & many more). If one is missing and you want us to add support for it, please reach out to our customer support.

The Verification flow automatically detects the language of the user's browser settings. If we support the language, the verification flow will be set to it. Otherwise the default is English.
