GraphQL

With a classic REST API, every endpoint returns a fixed data structure. The client either gets too many fields (overfetching) or has to combine multiple endpoints (underfetching). GraphQL solves both: the client sends a query that describes exactly the desired fields, the server returns exactly those fields.

For complex data models like product information that is a clear advantage. A mobile frontend needs different attributes than a B2B portal, a list view different from a detail page. With GraphQL, every frontend builds its optimal query, without requiring additional backend endpoints.

Pimcore offers GraphQL natively as an equal alternative to the REST API. The schema is generated automatically from the PIM data model, including classes, attributes, relationships, and classification systems. Permissions are enforced at the field level, enabling secure fine-grained access for different consumers.
