Introduction to APIs | Bondar Academy

Lesson Summary

In this lesson, we begin a new section on Interacting with APIs using Playwright, which offers robust support for working with APIs. Key functionalities include: Intercepting browser API calls Performing API calls and asserting or processing responses API testing capabilities Introduction to APIs API stands for Application Programming Interface , which allows interaction with a system through defined endpoints. For example, a weather API may have endpoints like getCityWeather and getCityForecast . Types of API Requests The most common types of API requests include: GET : Retrieve specific data POST : Create new data PUT : Update existing data DELETE : Remove data API Request Components A typical API request consists of: API URL : The endpoint to which the request is sent Headers : Includes content type and authorization tokens Body : A JSON object for POST or PUT requests Status Codes API responses include status codes to indicate the result: 200 : Success 300 : Redirection 400 : Client error (e.g., 404 for not found) 500 : Server error Playwright and API Interaction In Playwright, you can: Mock APIs to improve test speed and stability Intercept and modify API responses Make direct API calls for headless authorization This lesson provides a foundational understanding of APIs and how to interact with them using Playwright. See you in the next lesson!
