In GraphQL, the 'Schema' plays a critical role in API design by defining the data structure, types, and relationships within the API. It acts as a contract between the client and server, specifying what data can be queried and how it relates. The schema ensures consistency and clarity in communication between the client and server, making it a fundamental aspect of GraphQL API design.
