预先填充数据

这是一项可选功能，可让用户无需在嵌入式注册流程中重复输入公司信息。

Facebook 登录设置中 extras 对象的 setup 参数可以用来在嵌入式注册流程中为预填充表单传递数据。您可以传递所有数据字段或一个子集，以将其填充至表单中。举例来说，如果您只知道公司名称、邮箱和电话号码，那么您可以只传递这些信息。

示例

<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,

              country: 'US'
            },
            timezone: 'UTC-08:00'
          },
          phone: {
            displayName: 'Acme Inc',
            category: 'ENTERTAIN',
            description: 'Acme Inc. is a leading entertainment company.',
          }
        }
