What is an API
APIs define the ways in which others use the features and functions of a system, the way the requests are made and what the users get in return.
Why do APIs matter
One of the use cases of Messaging APIs is to provide bulk text messaging services for marketing team, such as sending promotional texts directly to customers’ phones. APIs are also used for sending notifications via text message. For example, tracking updates, shipping notices, order confirmations, etc.
In short, Messaging APIs define how to send, receive and manage text messages on a client’s mobile device. By using an API, app developers help improve navigation through their platforms, mobile apps and websites.
