What communication format does API testing often use?

• A. HTML
• B. CSV
• C. XML or JSON
• D. SQL

Answer: (C)

API testing primarily utilizes communication formats such as XML and JSON because these formats are widely accepted standards for data interchange in web services. Both XML (eXtensible Markup Language) and JSON (JavaScript Object Notation) are structured, making it easy to represent complex data hierarchies and arrays. They allow for efficient data serialization, which is crucial in API interactions where data is sent to and received from web services. XML is known for its verbosity and strict syntax rules, making it suitable for applications requiring detailed data descriptions and validation through schemas. On the other hand, JSON is lighter and easier to read, which often translates into faster parsing speeds in web applications, particularly in JavaScript-based environments. As a result, many modern APIs prefer JSON due to its efficiency and simplicity. In contrast, HTML is designed for web page rendering and is not structured for data interchange in API contexts. CSV, while useful for tabular data, lacks the ability to represent nested structures that XML and JSON can easily manage. SQL is primarily a query language for databases and not a format used for API requests or responses. Therefore, XML and JSON remain the leading formats in API testing for their adaptability and ease of use in web service interactions.
