I can get all the way up to the whitelist. But i dont understand where to input the code
This setup tool might be helpful if you're not so familiar with code: https://developers.facebook.com/docs/messenger-platform/discovery/facebook-chat-plugin/#setup_tool.
Otherwise, you need to include the SDK in your HTML file and then include this code snippet in the HTML:
<div class="fb-customerchat"
page_id="<PAGE_ID>">
</div>
It's well documented here: https://developers.facebook.com/docs/messenger-platform/discovery/facebook-chat-plugin/#include
thank you for getting back to me! This may sound stupid but where is this HTML file??
