# Rivr-Request-Id on every response from public-api

- Date: 2026-10-18
- Type: New
- Surface: /api/public
- What you need to do: Nothing.
- Address: https://developers.rivr.io/changelog/2026-10-18-rivr-request-id

Every response from public-api now carries the header Rivr-Request-Id: on /api/public for the calls that go through public-api (api.rivr.io is being moved over to it in steps, so not every /api/public call does yet). The value is a GUID that identifies the call at Rivr, and it is the same as `requestId` in an error body. Quote it when you contact Rivr and we can find the call in our logs. To use an id of your own, send exactly one Rivr-Request-Id header with a GUID; any other value is replaced by a new id, and the call is never refused because of it. In production since 2026-10-18 (public-api 0.12.0).
