API – Application Programming Interface

is a set of rules and protocols that allow different software applications to communicate and exchange data.

  • Bridges services, data, and features to other applications.
  • Creates new business opportunities by combining application features and data
  • The most commonly used API technologies are:
  • RESTful API: Based on REST principles. Uses HTTP methods (GET, POST, PUT, and DELETE)
  • GraphQL API: Uses a single endpoint to receive queries (HTTP, GraphQL).
  • SOAP API: Uses the SOAP protocol. Uses XML, and is more reliable and secure than REST API.
  • HTTP APIs are usually firewall friendly.
  • NOTE: There are also library APIs, but they can only bind to the same technology.
