If you are using a different site builder than WordPress, Wix, Squarespace, or Shopify, we recommend using the general embed code. Only in case the general embed is not supported on your site, use the iframe (will add link here) option.
After your item is published, click on the Share tab, choose the General Embed section, and copy the embed code:
In your site builder, edit the page you want to add your item to and find the embed element, often called "html editor" or signaled with a code icon. Paste the embed code, placing the element where you want to add the item, and save the changes.
