The HTTP Idempotency request header field can be used to carry idempotency key in order to make non-idempotent HTTP methods such as POST or PATCH fault-tolerant.

In this Breaking Changes tl;dr mini-episode, Postman Chief Evangelist Kin Lane welcomes Sanjay Dalal and Jayadeba Jena to discuss their recent submission of a draft to the IETF Network Working Group for an Idempotency-Key HTTP header field. The discussion aims to get insights into standardization within the API sector and understand the value of establishing standards from existing patterns.
