References across spaces is a feature by Contentful that allows you to link content across spaces (resource links). Using references, you can improve content reusability and enhance consistency within your organisation.

We improved the Content Delivery API (CDA) so you can retrieve resource links from different spaces in a single delivery API call.

Developers can now use references across spaces without having to make multiple API calls in parallel upon delivery. This new functionality will help you simplify your workflows, and reduce the complexity associated with your content delivery, resulting in increased efficiency and ease of use..

For more information, see the Resource Links section on the Content Delivery API page and the FAQs.
