Technical Requirements

FlatPlan handles the display and distribution of your content. All we need from you is the content, delivered via an RSS/Atom feed. For most publishers, the ‘full’ feed that comes as standard with their CMS will be sufficient, but below we have listed our feed requirements. Please ensure your feed meets these standards.

We need your feed to be valid, well-structured and contain everything we need. By this, we mean:

• Valid: confirmed by W3C validator as ‘valid’
• Well-structured: following the guidance below
• Everything we need: features every story you wish to appear on Apple News in its entirety
