Description: The link header is a type of HTTP header used to define relationships between resources in the context of HTTP APIs. This header allows developers to specify how different resources are related, facilitating navigation and interaction between them. For example, it can indicate that one resource is related to another or that a resource is a representation of another. Link headers are particularly useful in web applications where resources may be interdependent, as they provide a standardized way to describe these relationships. By using this header, the semantics of HTTP interactions are enhanced, allowing clients to better understand how to access and manipulate available resources. Additionally, it promotes interoperability between different systems and services by providing a common framework for describing relationships between resources. In summary, the link header is a key tool in the design of HTTP APIs, as it helps structure and clarify relationships between resources, thereby improving the experience for both developers and end users.
