An API, to use technical language, is the key to this expanding interconnectedness. A programming interface for applications enables sharing of data streams and functionality between various platforms. Developers can integrate software components without interacting with source code by using APIs as control panels. You can link third-party GDS/Wholesaler inventory/feeds with your website's booking engine using an API. As a result, when a customer uses your website to look for a flight or hotel, you will get apositive response in terms of payment instead of redirecting them to another website.Banks and other payment processors offer APIs for using their services, just like suppliers do to access their feeds. Travelers could use their credit card or debit card to make secure online payments by connecting a payment gateway API.
