Pre Filled Data

This is an optional feature that saves users the effort of re-entering their business information during the embedded signup process.

The setup parameter of the extras object in your Facebook Login setup can be used to pass data for pre filling forms in the embedded signup flow. You can pass all of the data fields or a subset to be filled in the forms. For example, if you only have the business’s name, email and phone number, you can pass that information alone.

Example

<script>
  window.fbAsyncInit = function () {
    // JavaScript SDK configuration and setup
    FB.init({
      appId:    'meta-app-id', // Meta App ID
      cookie:   true, // enable cookies
      xfbml:    true, // parse social plugins on this page
      version:  'v19.0' //Graph API version
    });
  };

  // Load the JavaScript SDK asynchronously
  (function (d, s, id) {
    var js, fjs = d.getElementsByTagName(s)[0];
    if (d.getElementById(id)) return;
    js = d.createElement(s); js.id = id;
    js.src = "https://connect.facebook.net/en_US/sdk.js";
    fjs.parentNode.insertBefore(js, fjs);
  }(document, 'script', 'facebook-jssdk'));

  // Facebook Login with JavaScript SDK
  function launchWhatsAppSignup() {
    // Conversion tracking code
    fbq && fbq('trackCustom', 'WhatsAppOnboardingStart', {appId: 'your-facebook-app-id', feature: 'whatsapp_embedded_signup'});
    
    // Launch Facebook login
    
  
  FB.login(function (response) {
      if (response.authResponse) {
        const code = response.authResponse.code;
        // The returned code must be transmitted to your backend
        // there must then perform a server-to-server call to our servers for an access token
      } else {
        console.log('User cancelled login or did not fully authorize.');
      }
    },  
    {	
      config_id: <CONFIG_ID>, // configuration ID goes here
      response_type: 'code',    // must be set to 'code' for System User access token
      override_default_response_type: true, // when true, any response types passed in the "response_type" will take precedence over the default types
      extras: {
        setup: {
          business: {
            name: 'Acme Inc.',
            email: 'johndoe@acme.com',
            phone: {
              code: 1,
              number: '6505551234'
            },
            website: 'https://www.acme.com',
            address: {
              streetAddress1: '1 Acme Way',
              city: 'Acme Town',
              state: 'CA',
              zipPostal: '94000',
              country: 'US'
            },
            timezone: 'UTC-08:00'
          },
          phone: {
            displayName: 'Acme Inc',
            category: 'ENTERTAIN',
            description: 'Acme Inc. is a leading entertainment company.',
          }
        }
      }
