Bahsedilen bağlantıya ek olarak, yazdığım bir modülün web servislerini kullanan bazı kodları. "Yapı" altında hizmet etkinleştirilmeli ve bir uç nokta tanımlanmalıdır. Burada izin verilen dönüş türlerini de ayarlayabilirsiniz.
Dolayısıyla, 'api' yi bitiş noktası olarak tanımlar ve bir json dizisi istiyorsanız, siteniz.com/api/servicename/arg1/arg2.json gibi bir istekte bulunursunuz. Hizmet adını hook_services_resources içinde tanımlarsınız.
