external services

APIs play a crucial role in web application development by allowing different software systems to communicate and share data. They act as a bridge between web applications and external services, enabling developers to leverage functionalities provided by third-party services. By integrating external services through APIs, web applications can access a wide range of features like payment processing, mapping, social media integration, and more. The integration process involves obtaining API keys or credentials, making API requests, and handling responses. APIs ensure seamless communication between web applications and external services, enhancing application functionality, scalability, and speed.
