The outcome describes something that happened once and never changes, so the console keeps showing it — including the warning that a probe-based import may not have found everything. That warning is worth reading once and is noise afterwards, so this is how you put it away. Answers `204` whether or not there was an outcome to discard: the request asks for a state, and that state is reached either way. ## OpenAPI ````yaml /api-reference/specs/dns.yaml delete /v1/zones/{zone_id}/record-import openapi: 3.0.3 info: title: Basaltic DNS API version: 1.0.0 description: | Authoritative hosted zones and their records, signed with DNSSEC.

This is the recommended way to authenticate. Get one by exchanging a service account's access key pair at `POST /v1/oauth/token` with `grant_type=client_credentials`. It is the standard client-credentials grant, so any OAuth-aware library will obtain and refresh it for you. ``` curl -s -u "$KEY_ID:$SECRET" -d grant_type=client_credentials \ https://iam.basaltic.sh/v1/oauth/token ``` Tokens last an hour by default. The same access key pair is separately your AWS SigV4 credential for the S3-compatible object endpoint, which speaks nothing else. SignatureAuth: type: apiKey in: header name: Authorization description: > Request signing with an access key issued to a service account. An HMAC-SHA256 over a canonical form of the request, close to AWS SigV4. The `basaltic` CLI signs for you. Send `Authorization`, `X-Date` (UTC, `YYYYMMDDTHHMMSSZ`) and `X-Nonce` (random per request); add `X-Content-Sha256` to bind a body, and `X-Amz-Security-Token` when using temporary credentials. ``` Authorization: BASALTIC-HMAC-SHA256 Credential=///basaltic/basaltic_request, SignedHeaders=host;x-date;x-nonce, Signature= ``` `` is the region code you are calling, or `global` for the global services. A signature is valid for 5 minutes from `X-Date`, and mutating requests are replay-guarded on the nonce. **Full signing procedure, including a working implementation:** https://docs.basaltic.sh/authentication ## Rate limits There is no global request budget. A limit applies only where an operation documents a `429`, and that operation says what it counts. Those responses carry `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset` and, on a `429`, `Retry-After` — read them rather than hard-coding a number. Retrying before `Retry-After` is refused and extends the window. Everything else is bounded by quota, not by request rate. ````
