API courses can help you learn how to design, build, and test application programming interfaces, as well as understand RESTful services and authentication methods. You can build skills in data exchange formats like JSON and XML, error handling, and API documentation practices. Many courses introduce tools such as Postman for testing APIs, Swagger for documentation, and various programming languages like Python or JavaScript to implement API calls, allowing you to effectively integrate and manage data across different systems.
