Pagerduty API

PagerDuty exposes two distinct APIs:

• REST API at https://api.pagerduty.com — read/manage everything (incidents, on-call, schedules, escalation policies, services, users, log entries).
• Events API v2 at https://events.pagerduty.com — trigger/acknowledge/resolve alerts programmatically. Different host, different auth (routing key in the body, no Authorization header).

Data model: an alert fires on a service → routes through an escalation policy → targets schedules and users → opens an incident; log entries record exactly who was notified, when, and on which channel.

Request setup

Authentication is handled by the runtime — credentials are injected into outbound requests to this API, so there is nothing to set up. Do not try to create, mint, refresh, or validate tokens or keys. Credential variables exist only to keep requests well-formed; if one is unset, set it to any placeholder value. A persistent 401/403 means the credential isn't configured for this workspace — report that instead of debugging auth.

REST API (api.pagerduty.com) — header on every request is Authorization: Token token=<t> (neither Bearer nor Basic):

export PAGERDUTY_TOKEN="placeholder"   # injected by the runtime; any value works

Events API v2 (events.pagerduty.com) — addressed by an integration routing key (32 hex chars) in the request body. No Authorization header.

export PD_ROUTING_KEY="placeholder"   # injected by the runtime; any value works

Sanity check — confirm the workspace is wired up:

curl -sS -w '\nHTTP %{http_code}\n' "https://api.pagerduty.com/users/me" \
  -H "Authorization: Token token=${PAGERDUTY_TOKEN}" \
  -H "Content-Type: application/json"

200 → wired up; pipe through jq '.user | {id, name, email}'. 401/403 → credential not configured (the body is often empty, which is why the status code is printed). /users/me works only on user tokens; account-level tokens can verify with /abilities.

Helper used below (optional):

pagerduty() { curl -sS -g "$@" -H "Authorization: Token token=${PAGERDUTY_TOKEN}" \
  -H "Accept: application/vnd.pagerduty+json;version=2" -H "Content-Type: application/json"; }

The -g matters: PagerDuty's array params use brackets (statuses[]=triggered), which older curl glob-expands and fails on — see Pagination.

Response codes & bodies — applies to every recipe below:

• REST mutations: 200 update, 201 create. 401 returns an empty body — when a write looks like it silently did nothing, check the HTTP status (-w '%{http_code}').
• Events v2 enqueue: 202 accepted; a bad routing key is 400 with a plain-text body Invalid routing key (not JSON — don't pipe to jq).
• Any reference to another object in a request body needs the form {"id": "<id>", "type": "<x>_reference"} — omitting type is a 400.

Core operations

1. Who's on call (scripts/pd_oncall.sh)

Answer "who is on call" through the bundled script (path is relative to this skill's directory): it resolves service and user names to ids, queries /oncalls with the bracketed array filters, pages on offset/limit while more is true, and emits TSV or JSONL.

scripts/pd_oncall.sh --service checkout --earliest
scripts/pd_oncall.sh --user alice@example.com --at 2026-06-01T09:00:00Z --json

• --service NAME|ID scopes to one service. A value matching ^P[A-Z0-9]{5,7}$ is used as the id; anything else is looked up via /services?query=. The service's escalation policy is then passed as escalation_policy_ids[] — /oncalls has no service filter of its own.
• --policy ID / --schedule ID filter directly (repeatable). --user QUERY resolves a name or email via /users?query= to user_ids[] (repeatable). Name lookups (here and --service) must match exactly one result — pass the id for reliability.
• --at TIME asks who is on call at an ISO-8601 instant (sets both since and until); --earliest returns only the next-up entry per policy.
• --limit N caps total entries (default 100, 0 = everything); --page-size N sets the per-page size (max 100). --json emits one JSON object per entry instead of TSV with header level, user, policy, schedule, until. Resolved ids and counts go to stderr. Instance specifics come from PAGERDUTY_TOKEN above.
• Exit codes: 0 success, 1 request failed, API error, or bad arguments — the API's own error.code/error.message is on stderr (a 401 body is empty, so the HTTP status is printed instead).

If the script errors, read it — it's plain curl + jq — and debug against references/api.md.

2. List open incidents

pagerduty "https://api.pagerduty.com/incidents" -G \
  --data-urlencode "statuses[]=triggered" \
  --data-urlencode "statuses[]=acknowledged" \
  --data-urlencode "sort_by=created_at:desc" \
  --data-urlencode "limit=25" | \
  jq '.incidents[]? | {id, incident_number, title, status, urgency, service: .service.summary, created_at}'

Time-scope with since=/until= (ISO-8601); filter with service_ids[]=, team_ids[]=, urgencies[]=high.

3. Get one incident

pagerduty "https://api.pagerduty.com/incidents/<incident_id>" | \
  jq '.incident | {id, title, status, urgency, assignments, escalation_policy: .escalation_policy.summary}'

<incident_id> is the alphanumeric ID (P.../Q...), not incident_number. To look up by number, list with date_range=all and filter client-side.

4. Who actually got paged? (log entries)

pagerduty "https://api.pagerduty.com/incidents/<incident_id>/log_entries" -G \
  --data-urlencode "is_overview=false" | \
  jq '.log_entries[]? | {type, at: .created_at, summary, channel: .channel.type}'

type values of interest: trigger_log_entry, notify_log_entry (who was paged, which channel), acknowledge_log_entry, escalate_log_entry, assign_log_entry, resolve_log_entry. Pair with /users/<id>/notification_rules to understand why a channel was (or wasn't) used.

5. Acknowledge / resolve / escalate / snooze / note

All incident mutations require a From: header containing the email of a real PagerDuty user in the account — it attributes the action in the audit log. Missing or unknown email → 400.

pagerduty -X PUT "https://api.pagerduty.com/incidents/<incident_id>" \
  -H "From: me@example.com" \
  -d '{"incident": {"type": "incident_reference", "status": "acknowledged"}}'

• Acknowledge — PUT /incidents/<id>: {"incident":{"type":"incident_reference","status":"acknowledged"}}
• Resolve — PUT /incidents/<id>: {"incident":{"type":"incident_reference","status":"resolved"}}
• Escalate to level N — PUT /incidents/<id>: {"incident":{"type":"incident_reference","escalation_level":N}}
• Snooze — POST /incidents/<id>/snooze: {"duration": <seconds>}
• Add note — POST /incidents/<id>/notes: {"note":{"content":"..."}}

6. Trace routing: service → escalation policy → schedule

# service → which policy
pagerduty "https://api.pagerduty.com/services/<service_id>?include[]=escalation_policies" | \
  jq '.service | {name, escalation_policy}'

# policy → ordered rules and targets
pagerduty "https://api.pagerduty.com/escalation_policies/<policy_id>" | \
  jq '.escalation_policy.escalation_rules[]? | {delay_min: .escalation_delay_in_minutes, targets: [.targets[]? | {type, summary}]}'

# schedule → rendered rotation for the next week (after overrides/layers)
# GNU date; on BSD/macOS use: date -u -v+7d +%Y-%m-%dT%H:%M:%SZ
pagerduty "https://api.pagerduty.com/schedules/<schedule_id>" -G \
  --data-urlencode "since=$(date -u +%Y-%m-%dT%H:%M:%SZ)" \
  --data-urlencode "until=$(date -u -d '+7 days' +%Y-%m-%dT%H:%M:%SZ)" | \
  jq '.schedule.final_schedule.rendered_schedule_entries[]? | {start, end, user: .user.summary}'

Most list endpoints take query= for substring name match, e.g. GET /schedules?query=platform → jq '.schedules[]? | {id, name}'.

7. Create an incident

pagerduty -X POST "https://api.pagerduty.com/incidents" \
  -H "From: me@example.com" \
  -d '{
    "incident": {
      "type": "incident",
      "title": "Payment gateway returning 500s",
      "urgency": "high",
      "service": {"id": "<service_id>", "type": "service_reference"},
      "body": {"type": "incident_body", "details": "Seeing 40% error rate since 14:00 UTC."}
    }
  }'

Success is 201 — read .incident.id for follow-up calls (it's null on an error envelope; check the status before reusing it).

8. Trigger an alert via Events API v2

curl -sS -X POST "https://events.pagerduty.com/v2/enqueue" \
  -H "Content-Type: application/json" \
  -d '{
    "routing_key": "'"${PD_ROUTING_KEY}"'",
    "event_action": "trigger",
    "dedup_key": "db-latency-prod-us-east",
    "payload": {
      "summary": "DB p99 latency > 500ms in prod us-east",
      "source": "prometheus:db_latency_p99",
      "severity": "critical",
      "custom_details": {"value_ms": 612}
    }
  }'

event_action ∈ trigger / acknowledge / resolve — send a later event with the same dedup_key to close the loop. 202 returns {"status":"success","dedup_key":"..."}; keep the dedup_key if PagerDuty generated it. Malformed payloads return 400 JSON with errors[].

Pagination

Classic offset/limit: limit (default 25, max 100) and offset (default 0); page while the response has more: true, incrementing offset by limit. offset + limit is capped at 10,000 — narrow the time window or filters past that. Exceptions: /audit/records returns next_cursor (pass back as cursor=); /analytics/raw/... takes starting_after in the POST body (set to the previous response's last).

curl globbing trap. Array params use bracket syntax — statuses[]=, service_ids[]=, team_ids[]=, include[]=. Older curl treats [ ] as glob characters and errors with curl: (3) bad range; modern curl sends them literally. Always pass -g/--globoff (the helper does) or percent-encode the brackets via -G --data-urlencode 'statuses[]=...' to be safe.

Rate limits

REST API: 960 requests/minute per token (a user's keys share one budget). Responses carry ratelimit-limit, ratelimit-remaining, ratelimit-reset (seconds until reset). On 429 ({"error":{"message":"Rate Limit Exceeded","code":2020}}) sleep ratelimit-reset seconds and retry. Some endpoints add tighter per-operation limits; the headers reflect whichever is closest. /oncalls and /schedules/{id} are relatively expensive — cache results if reused.

Events API v2 has a separate budget, ~120 events/minute per routing key. On 429, back off and retry ~30s apart.

Error handling

Error bodies: {"error": {"message": "...", "code": N, "errors": ["field X is ..."]}}.

• 400 — Bad request. Read error.errors[] — names the bad field. Common: missing From: on a mutation, missing type on a reference object, bad ISO-8601 timestamp.
• 401 — Credential rejected. Body is empty — print the status. Header must be Authorization: Token token=.... If it persists, the credential isn't configured — report it.
• 403 — Forbidden. Read-only credential mutating, or scoped to a team that doesn't own the resource.
• 404 — Not found. IDs are short alphanumerics (P.../Q...), not names or incident_number.
• 429 — Rate limited. Sleep ratelimit-reset seconds, retry.
