Technically speaking, idempotency as defined by RFC7231 only requires f(x) = f(f(x)).
- jholman 8y agoYes, and nullipotency requires x = f(x) = f(f(x)), and four of the methods defined in RFC7231 are expected to be nullipotent, otherwise known as "safe". The point of mentioning that is to highlight the relationship between idempotence and nullipotence.
