Σύντομη απάντηση
A query language for APIs that lets the client request exactly the data it needs, in a single call.
Βασικά συμπεράσματα
- REST - fixed endpoints, predefined response
- GraphQL - one flexible query, response exact to the request
What GraphQL is
GraphQL is a query language for APIs: the client specifies exactly which fields it wants, and the server returns precisely that data, in one request. An alternative to REST for interconnected-data cases.
Why it matters
It reduces the over-fetching (too much data) and under-fetching (too many calls) typical of REST. Useful for rich interfaces (portals, commerce apps) displaying data from many entities.
GraphQL vs REST
- REST - fixed endpoints, predefined response
- GraphQL - one flexible query, response exact to the request
How CRMconnect helps
CRMconnect exposes operational data (stock, orders, statuses) through modern APIs, including GraphQL patterns where consumers need flexible queries, e.g. the B2B portal and commerce integrations.
Πραγματικό παράδειγμα
A B2B portal showed the customer profile, history and stock in 4 separate REST calls. With a single query on the CRMconnect layer, the page loaded faster and with fewer requests.

Συχνές ερωτήσεις
Does GraphQL replace REST?+
Not necessarily. They coexist: REST is simple and robust for clear operations; GraphQL shines when the client needs flexible, interconnected data.
When is GraphQL worth it?+
When you have rich interfaces combining many entities and want to avoid many calls or redundant data.
