Why is Resource Modeling important in REST API design?

A resource can be a singleton or a collection.
What is difference between REST API and Domain Driven Design?
It is very important to distinguish between resources in REST API and domain entities in a domain driven design. Domain driven design applies to the implementation side of things (including API implementation) while resources in REST API drive the API design and contract.
