Rescan, superseding an import session

posthttps://api.nsin.ir/domains/{domain}/records/import-sessions/{sessionId}/rescan

Auth: Authorization: Bearer nsin_… or X-Api-Key: nsin_… — see API keys.

Marks this session superseded and starts a fresh one against the same nameservers the original scan read. Requires records.edit.

Reusing the stored nameservers is the whole point: once the domain is delegated to NSIN, resolving its nameservers again finds ours, and a rescan would transfer our own still-empty zone and report that the old provider had nothing.

The old session is kept rather than rewritten, so a rescan can never race a commit already in flight, and the record of what was originally found survives.

Path parameters

  • domainstringrequiredpath

    The domain name (for example example.com) — not a numeric id.

  • sessionIdintegerrequiredpath

    Numeric id of the record import session. Sessions are resolved within the domain, so an id from another domain reads as not found.

Responses

200An open session already existed and is returned unchanged.

Content type: application/json

  • idinteger
  • domain_idinteger
  • statusstring

    scanning — the sweep is running. ready — waiting for a commit or a discard. committing — a commit is in flight and holds the claim. auto_committed — nobody answered before auto_commit_at and the records were written anyway, rather than leaving the zone empty. superseded — replaced by a rescan.

    One of: "scanning" "ready" "committing" "committed" "auto_committed" "discarded" "superseded" "failed"
  • sourcestring
    One of: "manual_scan" "domain_create" "zone_file"
  • clientstring

    What started the session. An API key has nowhere to show a review screen, so adding a domain with a key still imports automatically; staged review is the panel path.

    One of: "panel" "api"
  • methodstring

    Which branch found the records — a full zone transfer, or a resolver sweep of common names. The first support question about a bad import is where the records came from.

    One of: "axfr" "scan"
  • source_nsarray of string

    The nameservers this scan read. Stored because a rescan has to reuse them: once the domain is delegated to NSIN, resolving it again finds our own — still empty — zone.

  • errorstring

    Why the scan, or the last commit attempt, failed.

  • started_atstring (date-time)
  • finished_atstring (date-time)

    When the scan finished and the session turned ready.

  • committed_atstring (date-time)
  • auto_commit_atstring (date-time)

    When an unanswered ready session commits itself. Cleared by a commit, a discard or a rescan.

  • countsImportSessionCounts

    The header line of a review screen.

    Fields
    • totalinteger
    • preselectedinteger

      Rows a mode "all" commit would write.

    • proxiedinteger
    • warningsinteger

      Rows carrying at least one warning.

  • recordsarray of ImportSessionRecord

    Empty while status is scanning.

    Item fields
    • idinteger

      Staging row id. It is not a record id — it exists only until the session is committed or discarded.

    • namestring
    • typestring
      One of: "A" "AAAA" "CNAME" "ANAME" "NS" "TXT" "MX" "SRV" "PTR" "CAA" "TLSA" "SSHFP" "URI"
    • destinationstring
    • ttlinteger
    • mx_priorityinteger
    • proxiedboolean

      Whether this row would be proxied — and, because a mode: "all" commit (the unattended auto_commit_at one included) writes exactly this flag, what happens to the row if nobody answers.

      It is true for the rows the edge can carry: a proxyable type on a routable origin. It is false wherever proxying would take a service away rather than accelerate it — a mail host, the target of an in-zone MX, an underscored name (_acme-challenge, selector1._domainkey), or a label that names something that does not speak HTTP (ssh, vpn, mysql, ns1, …). Those rows carry a mail_host or non_web_service warning saying so.

      An overwrite row mirrors the record it would replace: an import refreshes content and TTL and never changes an existing record's proxy setting.

    • statusstring

      overwrite means the domain already holds a record with this name and type and it would be replaced. TXT is never overwrite: many TXT records share one name.

      One of: "new" "overwrite" "unsupported"
    • existing_idinteger

      The record that would be replaced. Set when status is overwrite.

    • proxy_eligibleboolean

      Whether this row could be proxied if you switched it on — a proxyable type pointing at an address the edge will accept.

    • preselectedboolean

      Whether the row is included when you commit with mode: "all". Rows carrying an error warning arrive unticked.

    • warningsarray of ImportWarning
      Item fields
      • codestring
        One of: "unsupported" "not_proxyable_type" "private_address" "points_at_nsin" "proxy_ineligible_origin" "mail_host" "non_web_service" "overwrite" "wildcard"
      • severitystring

        Only error rows arrive unticked (preselected: false) — they are the ones NSIN cannot import at all.

        One of: "info" "warning" "error"
      • messagestring
    • reasonstring

      The first warning's message, kept for clients written against the flat scan preview.
