This article is about the Proxi admin app at app.proxi.co.
Some places don't accept pasted code at all. Your Proxi link still works everywhere, and a few of these will frame it for you. Copy the link from the Link tab of the Share dialog.
Canva Websites
Add an Embed element and paste the link. Canva displays the page inside your site. There's no way to paste code on any Canva plan, so the link is the route.
Notion
Type /embed on the page, paste the link, and choose Embed link. Drag the frame taller so a map has room.
Facebook, Instagram, Linktree, and Other Link Pages
These take links only. Post the link, or add it as a button on your link page. Set a Preview image and Page title in your map editor's Sharing section so the link card looks good, and consider the QR Code tab for printed pieces.
Email Newsletters
Email can't run embeds. Use a button or an image linking to your map; a screenshot of the map with a "Open the map" button underneath works well.
