When building APIs, ๐‘๐„๐’๐“ and ๐ ๐‘๐๐‚ are two popular options, each with its strengths and weaknesses. Hereโ€™s a quick breakdown to help you decide when to use each one.

๐—ฅ๐—˜๐—ฆ๐—ง is a widely-used API protocol based on ๐—›๐—ง๐—ง๐—ฃ/๐Ÿญ.๐Ÿญ. Itโ€™s suitable for web applications that prioritize ๐—ฒ๐—ฎ๐˜€๐—ฒ ๐—ผ๐—ณ ๐˜‚๐˜€๐—ฒ, ๐—ต๐˜‚๐—บ๐—ฎ๐—ป ๐—ฟ๐—ฒ๐—ฎ๐—ฑ๐—ฎ๐—ฏ๐—ถ๐—น๐—ถ๐˜๐˜†, ๐—ฎ๐—ป๐—ฑ ๐—ฏ๐—ฟ๐—ผ๐—ฎ๐—ฑ ๐—ฐ๐—น๐—ถ๐—ฒ๐—ป๐˜ ๐—ฐ๐—ผ๐—บ๐—ฝ๐—ฎ๐˜๐—ถ๐—ฏ๐—ถ๐—น๐—ถ๐˜๐˜†.

โ€ข ๐—ฃ๐—ฟ๐—ผ๐˜€: Easy to understand, browser-friendly, supported across multiple platforms.
โ€ข ๐—–๐—ผ๐—ป๐˜€: Higher latency, less efficient for high-throughput requirements, limited to JSON and XML payloads.

Use ๐—ฅ๐—˜๐—ฆ๐—ง for simplicity and ๐—ด๐—ฅ๐—ฃ๐—– for performance-sensitive applications. Each serves different needs, so pick the protocol that best fits your applicationโ€™s requirements!
