RESTful API courses can help you learn how to design, implement, and consume APIs, as well as understand HTTP methods, status codes, and data formats like JSON and XML. You can build skills in authentication techniques, error handling, and versioning strategies to ensure robust API functionality. Many courses introduce tools such as Postman for testing APIs and Swagger for documentation, that support streamlining the development process and enhancing collaboration among teams.
