API Nedir?<\/h2>\n

API, \u0130ngilizce a\u00e7\u0131l\u0131m\u0131yla Application Programming Interface<\/strong>, T\u00fcrk\u00e7esiyle Uygulama Programlama Aray\u00fcz\u00fc<\/strong> anlam\u0131na gelir. API, bir yaz\u0131l\u0131m\u0131n ba\u015fka bir yaz\u0131l\u0131mla belirli kurallar \u00e7er\u00e7evesinde ileti\u015fim kurmas\u0131na olanak tan\u0131yan bir aray\u00fczd\u00fcr. Basit bir \u00f6rnekle anlatmak gerekirse: API, bir garson gibidir. M\u00fc\u015fteri (uygulama) ile mutfak (sunucu) aras\u0131nda sipari\u015fi ileten ve sonucu geri getiren arac\u0131 bir yap\u0131 olarak g\u00f6rev yapar.<\/p>\n

API\u2019ler, farkl\u0131 yaz\u0131l\u0131mlar\u0131n veya servislerin birbirleriyle veri al\u0131\u015fveri\u015fi yapabilmesini sa\u011flar. \u00d6rne\u011fin bir hava durumu uygulamas\u0131, ba\u015fka bir servisin sa\u011flad\u0131\u011f\u0131 API \u00fczerinden g\u00fcncel verileri alarak size g\u00f6sterir. Bu sayede yaz\u0131l\u0131m geli\u015ftiriciler her \u015feyi s\u0131f\u0131rdan kodlamak yerine var olan verileri veya i\u015flevleri kolayca kullanabilir.<\/p>\n
