VCard click handler

This feature requires you to register your app as a service first.

In SMS messages, user can receive vcard (contact) file with MMS. We allow third party to handle the vard attachment download event. For example, when user click vcard file download button, your service will receive the vcard URI, and save the contact into your service.

First, register service with vcardHandlerPath:

document.querySelector("#rc-widget-adapter-frame").contentWindow.postMessage({
  type: 'rc-adapter-register-third-party-service',
  service: {
    name: 'TestService',
    vcardHandlerPath: '/vcardHandler',
  }
}, '*');

Add a message event to listen vcard click event:

window.addEventListener('message', function (e) {
  var data = e.data;
  if (data && data.type === 'rc-post-message-request') {
    if (data.path === '/vcardHandler') {
      // add your codes here to handle the vcard file download event
      console.log(data.body.vcardUri);
      // response to widget
      document.querySelector("#rc-widget-adapter-frame").contentWindow.postMessage({
        type: 'rc-post-message-response',
        responseId: data.requestId,
        response: { data: 'ok' },
      }, '*');
    }
  }
});
