🔧 HTTP Methods Reference

Nine HTTP methods, each with a different intent. Some are safe (no side effects), some are idempotent (calling twice = calling once), some create resources, some delete. This reference covers all of them with examples and gotchas.

Frequently asked questions

PUT vs PATCH?

PUT replaces the entire resource. PATCH updates specific fields. PUT is idempotent. PATCH may or may not be — depends on what you patch.
