Nyligen publicerade jag en artikel om PayPal Payment Gateway Integration i PHP<\/a>. I den artikeln fr\u00e5gade en av v\u00e5ra l\u00e4sare om att integrera PayPal-betalningsporten i Laravel. \u00c4ven om Laravel \u00e4r byggt med PHP har de sina egna standarder att f\u00f6lja. Du m\u00e5ste justera din vanliga PHP-kod enligt Laravel-fl\u00f6de. I den h\u00e4r artikeln visar jag dig hur du accepterar betalning p\u00e5 din Laravel-webbplats med PayPal Rest API.<\/p>\n

PayPal \u00e4r ett av de mest betrodda varum\u00e4rkena som accepterar onlinebetalning. PayPal erbjuder olika s\u00e4tt att integrera sitt betalningssystem i webbapplikationer. En av tj\u00e4nsterna \u00e4r PayPal Rest API som vi kommer att anv\u00e4nda f\u00f6r denna handledning. F\u00f6r att komma ig\u00e5ng m\u00e5ste du f\u00f6rst ta tag i ditt klient-id och klienthemlighet.<\/p>\n

G\u00e5 \u00f6ver till ditt PayPal-utvecklarkonto<\/a> och logga in p\u00e5 det. Klicka p\u00e5 menyn ’Mina appar och referenser’ i instrumentpanelen f\u00f6r utvecklare. Klicka sedan p\u00e5 knappen "Skapa app" under avsnittet REST API-appar.<\/p>\n

F\u00f6lj stegen enligt uppmaningen s\u00e5 f\u00e5r du din sandl\u00e5da och live-referenser. F\u00f6r nu, kopiera klient-id och klienthemlighet i sandbox-l\u00e4ge.<\/p>\n

PayPal Payment Gateway-integration i Laravel<\/h3>\n
Att integrera API f\u00f6r betalningsgateways i applikationen \u00e4r ganska komplicerat. Lyckligtvis gjorde Omnipay-biblioteket utvecklarnas liv l\u00e4tt. Omnipay<\/a> \u00e4r det mest popul\u00e4ra betalningshanteringsbiblioteket f\u00f6r PHP. Det ger en enkel och ren kod f\u00f6r att integrera olika betalningsportaler. Installera Omnipay-biblioteket med kommandot:<\/p>\n
