The use of APIs has become increasingly popular with the rise of [[microservices-architecture|microservices architecture]] and [[cloud-computing|cloud computing]], allowing for greater flexibility and scalability in software development. APIs can be used to retrieve data from [[databases|databases]], send notifications through [[sms-gateway|SMS gateways]], or even interact with [[internet-of-things|Internet of Things]] devices.
