# Idempotency

> How idempotency will be documented.

<Note>
  The External Integration API is not generally available. Nothing on this page
  is a production endpoint, credential, or response schema.
</Note>

If the approved API supports idempotent writes, the OpenAPI contract will name the header or field and the operations that require it. This page will explain retry behavior for those operations.

No idempotency header is published today. Retrying an unpublished operation is not supported.
