**Good to know:** Using the 'Page Link' block lets you link directly to a page. If this page's name, URL or parent location changes, the reference will be kept up to date. You can also mention a page – like [items](https://developer.salescamp.app/reference/api-reference/items "mention") – if you don't want a block-level link.
