You can improve the functionality of your app by using one of a thousand ready-made APIs provided by various services. When you don’t have a huge investment but want to give a visitor an unforgettable experience with features like navigation, social login, and a menu database, the use of a third-party API is always a good idea. Many firms, such as Google Maps, Twitter, Facebook, and PayPal, provide third-party integration, allowing developers to access their data or services.
