Twilio Flex + ActiveCampaign Integration

We are looking to integrate our Twilio Flex Center with ActiveCampaign. I have started the development, but am running into some issues. Here is our ideal flow: 1.) Incoming Call → Task Clicked → GET request to ActiveCampaign (to retrieve contact by phone) 2.) If a contact was found via phone, send URL to iframe (i.e. [login to view URL]) 3.) Upon Task Completion → navigate back to base url ([login to view URL]) I have successfully added a plugin to display the ActiveCampaign iFrame in Flex, but have been receiving errors around the same-origin policy. The ActiveCampaign home page loads fine, but I cannot navigate outside of it without an uncaught DOM exception. I've looked into using postMessage(), but do not think it is possible without having direct access to ActiveCampaign's markup. I have also come across a skeleton framework that may be useful, and a better way to go about addressing this: [login to view URL] Ideally, you’ll be able to help address this issue ASAP. Then, if successful, I’d like to look to your expertise, and be able to consult with you on a regular basis as we look to add functionality to our flex application. Thanks,
