Request IDs
Noryo-Request-Id identifies one HTTP attempt: its shape, why it changes on every retry, where to find it, and how to use it with support.
Noryo-Request-Id identifies one HTTP attempt. Noryo creates it for every request received, and it is the only handle support needs to find out what happened.
noryo-request-id: req_01a07868-6443-79fa-a4c8-221f1745244fHTTPIts properties
| Property | Value |
|---|---|
| Shape | req_ followed by a version 7 UUID |
| Ordering | Time-ordered: sorting by identifier means sorting by arrival time |
| Where | The Noryo-Request-Id header of every response, success or error; the request_id field of every error body |
| Uniqueness | One attempt, one identifier: the same in the header, the body and Noryo's logs, including on a 500 |
| Who chooses it | Noryo only. A Noryo-Request-Id sent by the client is ignored and replaced. |
New on every attempt
A retry is a new attempt, hence a new identifier, even when it returns a memorised response:
| Attempt | Idempotency-Key | Noryo-Request-Id | Noryo-Idempotency-Replayed |
|---|---|---|---|
| 1 | demo-001 | req_01a07868-… | false |
| 2 (retry) | demo-001 | req_01a0786b-… | true |
The Idempotency-Key links the attempts of one operation; the Noryo-Request-Id tells each of them apart. Log both.
In a replayed body, the content is that of the first response; the identifier of the current attempt is the one in the header.
Where to find it later
- In your logs, if you write it there: that is the recommendation.
- On the Usage page of Platform, under recent calls: every call that produced a result appears with its
request_id, its date, itsenrichment_id, its result and its units, engine failures included. Replays (byIdempotency-Keyor byexternal_transaction_id) and attempts refused before computation (a401, a validation400, a429) do not appear there.
With support
Quote the Noryo-Request-Id of the attempt concerned. It is enough to find the exact attempt in Noryo's logs: the route, the status returned, the error code, the time spent per step. You do not need to pass on your key, the descriptor or the external_transaction_id: never send them to support.
What to log on your side
const res = await fetch(url, init);
logger.info({
noryo_request_id: res.headers.get("noryo-request-id"),
idempotency_key: idempotencyKey,
status: res.status,
replayed: res.headers.get("noryo-idempotency-replayed"),
});TypeScriptNever log the Authorization header.
