incidents/get_incidents/ answers with a summary and nothing else: 21 fields,
no hosts, no users, no MITRE, no tags, and not one of the alerts the incident
aggregates. Ingesting through it leaves an incident whose raw payload says
almost nothing about what happened — and the shipped mapper had been written
for a richer shape than the endpoint ever returns, mapping hosts[0], users[0]
and mitre_* that simply are not in that response.
incidents/get_multiple_incidents_extra_data/ returns the same incidents with
39 fields, every alert in full — 156 fields each — and the file and network
artifacts. It is what the reference client fetches through (demisto/content,
CortexXDRIR.get_multiple_incidents_extra_data), and full_alert_fields must be
set or the nested alerts come back trimmed to a handful of fields.
Records arrive as {incident, alerts, network_artifacts, file_artifacts} with
each nested block wrapped as {total_count, data}. The script flattens them, so
every expression written against get_incidents keeps working — the summary's
21 fields are a subset of these 39 — while the alerts and artifacts land beside
them as plain lists, and their total_count says when a list is a sample rather
than the whole set. incident_sources is lifted into a scalar for the same
reason severity was on the alerts side: the incident-field mapper reads dotted
paths and cannot index a list.
get_incidents stays, for cheap polling, and now says in its description what it
does and does not carry.
The mapper maps the aggregate first and the first alert last, so the alert
fills in whatever the aggregate leaves silent — including the detection anchor,
since an XDR incident's detection_time is usually null while its alerts carry
theirs. Verified against the vendor's recorded response
(test_data/get_multiple_incidents_extra_data.json): 33 of 52 entries resolve,
severity critical lands on 5, source reads "XDR Agent", and the anchor falls
through to the alert's detection timestamp.

get_alerts posted the incidents body, {filters, search_from, search_to, sort},
to alerts/get_alerts_by_filter_data/. That endpoint serves the alerts GRID and
speaks another dialect entirely, so every call — before this branch as much as
after it — came back a bare HTTP 500 with no hint as to why.
Shape taken from the reference client (demisto/content, Packs/ApiModules/
Scripts/CoreIRApiModule, get_alerts_by_filter_command):
request_data.filter_data = {
sort: [{FIELD, ORDER}], # a list, uppercase keys
paging: {from, to}, # not search_from/search_to
filter: {AND: [{SEARCH_FIELD, SEARCH_TYPE, SEARCH_VALUE}]},
}
Severity is an enum there (SEV_040_HIGH), and several severities are OR'd, not
passed as a list. The watermark is a RANGE, since the grid has no gte operator;
its upper bound carries five minutes of slack, because our clock and the
tenant's are not the same clock. A filterless query is bounded to the last
thirty days rather than sent empty — the reference client refuses one outright,
and the grid is not meant to be asked for a whole retention.
The response needed as much work as the request. Rows arrive wrapped as
{alert_fields, incident_fields}, and mapping through that wrapper would put an
alert_fields. prefix on every expression an operator writes, so each row is
unwrapped. Two of its fields cannot be mapped as they stand: severity is the
enum code, and status.progress carries a dot INSIDE the key, which no mapping
path can express. Both are derived into severity_name and status_progress.
The mapper follows the grid's own vocabulary — internal_id, alert_name,
agent_hostname, agent_ip_addresses — and dedup moves to internal_id, since
alert_id belongs to the other API. case_id is kept as the correlation UID: it
is the join back to the incident feed.
Verified end to end against the vendor's own recorded response
(test_data/get_alerts_by_filter_results.json): 33 of 54 OCSF entries resolve on
it, severity lands on 3, the detection anchor is set, and the paging walks
0-100, 100-200, 200-250 with the truncation flag raised only when the ceiling,
not the window, ended the fetch.

An XDR incident is an aggregate; the SOC works the detections under it. The
alerts endpoint was already exposed as a read command, but nothing could feed
an alert rule with it — no results path, no dedup key, no watermark, no mapper,
no incident type. All five are here now, so an alert rule can be pointed at
reply.alerts the same way it is pointed at reply.incidents.
get_alerts pages past the API's 100-results-per-call ceiling: an alert feed
carries far more than a hundred detections between two polls, and whatever a
single page leaves behind is never fetched again, because the next run's
watermark has already moved past it. On an incremental fetch it also sorts
oldest first, so a window larger than the limit drops its most recent alerts —
the only ones the next poll can still see — and says so via `truncated`.
Two fixes to the incident side while in the same files:
- The severity expression compared strings, which the mapping engine cannot do
(it reads numeric comparisons only). Every test read as false, so every
ingested incident silently took the alert rule's default severity. The bare
field works: Riposte maps critical/high/medium/low onto 1-5 itself.
- The incident mapper carried no `time`, so the detection anchor was missing
and MTTD stayed empty for the whole feed. creation_time fills it.

A tenant URL that is not the API host answers 200 with the console's HTML
shell, and the client turned that into "Expecting value: line 1 column 1
(char 0)" — a JSON parse error that names neither the URL nor the response.
The shared client now reports the status, content type and first bytes of any
non-JSON reply, and points at the API host the operator was meant to copy.
Around it, the URL is reduced to scheme + host so a pasted /public_api/v1 or
console path cannot double the API root, a missing key or key ID is refused
before the request, and 401/403 recalls the three usual causes (auth mode,
revoked key, clock skew).
Nonce and timestamp now ride along in standard mode too, matching the
reference client, and test_connection probes get_incidents — the read that
ingestion actually depends on — instead of the distribution versions.
Add three commands to the Cortex XDR integration (v1.2.0):
- update_incident: change status, severity, assignment and resolve
comment on an incident (closes the SOAR ingest→action loop).
- insert_parsed_alerts: push external parsed alerts into Cortex XDR.
- insert_cef_alerts: push external CEF-format alerts.
Scripts follow the existing self-contained standard/advanced auth pattern.

cortex-xdr, crowdstrike, harfanglab and splunk now ship an `ingestion` block
(fetch command + bundled mapper + default incident type) and a bundled default
incident type under incident-types/, so the instance Collect section is pre-filled
on first configuration and the default type is created on install.
