Intercom Incident Runbook

Overview

Rapid incident response procedures for Intercom integration failures. The runbook takes you from alert to resolution in four phases — triage, decision, mitigation, and postmortem — with HTTP-status-code-driven branching so you always know whether the fault is yours or Intercom's. High-level workflow lives here; the full copy-paste scripts and templates live in references/.

Prerequisites

• INTERCOM_ACCESS_TOKEN exported in your shell (a workspace admin token).
• curl and jq installed for API + status-page probing.
• kubectl access to the deployment running your Intercom integration (for restarts).
• Access to your secret manager (e.g. AWS Secrets Manager) to rotate a compromised token.
• Developer Hub access for the Intercom app, or a path to escalate to a workspace admin.

Severity Levels

Level	Definition	Response Time	Example
P1	All Intercom API calls failing	< 15 min	401 auth failures, API unreachable
P2	Degraded service	< 1 hour	High latency, rate limited (429)
P3	Partial impact	< 4 hours	Webhook delays, search timeouts
P4	No user impact	Next business day	Monitoring gaps, stale cache

Instructions

Work the phases in order. Each phase links to the full reference when you need depth.

1. Assign severity. Match the symptom to the table above; this sets your clock and who you page.

2. Triage — is it you or Intercom? Run the first probe to confirm reachability:

   curl -s -o /dev/null -w "%{http_code}" \
     -H "Authorization: Bearer $INTERCOM_ACCESS_TOKEN" \
     https://api.intercom.io/me
   

   Then check status.intercom.com for a platform incident and read the rate-limit headers. The full 5-step diagnostic script and the branch-by-branch decision tree are in references/triage.md.

3. Decide. If Intercom reports an incident, it is their problem — enable graceful degradation and monitor. If not, it is your integration; branch on the status code: 401 → rotate token, 403 → add OAuth scope, 429 → queue/backoff, 5xx → retry with backoff.

4. Mitigate by error type. Apply the matching remediation — token rotation for 401, volume reduction for 429, cached-data fallback for 5xx. Full commands (including the aws secretsmanager rotation and the kubectl rollout restart) plus the TypeScript graceful-degradation pattern are in references/mitigation.md.

5. Communicate. Post the internal Slack status update on a fixed cadence using the template in references/templates.md.

6. Write the postmortem. After resolution, fill in the postmortem template (timeline, root cause, impact counts, action items) from references/templates.md. Always record Intercom request_ids captured during the incident — Intercom support needs them.

Output

Working through the runbook produces:

• A severity classification (P1–P4) with a bounded response clock.
• A fault verdict — Intercom-side platform incident vs. your integration — backed by the triage script's HTTP codes, status-page state, and rate-limit headers.
• A mitigation applied for the specific error class (rotated token, paused sync jobs, enabled cache fallback, or retry/backoff).
• A communication trail — timestamped Slack updates on cadence.
• A completed postmortem with timeline, root cause, impact counts, captured Intercom request_ids, and owned action items.

Examples

Fast triage during a suspected outage — confirm reachability, then check the platform:

curl -s -o /dev/null -w "API=%{http_code}\n" \
  -H "Authorization: Bearer $INTERCOM_ACCESS_TOKEN" https://api.intercom.io/me
curl -s https://status.intercom.com/api/v2/status.json | jq -r '.status.description'

A 401 with a green status page means your token, not Intercom — jump to the 401 mitigation. The full 5-step diagnostic, the decision tree, per-status mitigation commands, and the Slack/postmortem templates are all in references/:

• references/triage.md — full triage script + decision tree
• references/mitigation.md — 401 / 429 / 5xx remediation + graceful degradation
• references/templates.md — Slack update + postmortem templates

Error Handling

Issue	Cause	Solution
Triage script fails	Token not set	Export INTERCOM_ACCESS_TOKEN
Status page unreachable	DNS/network	Try mobile network or VPN
Can't rotate token	No Developer Hub access	Escalate to workspace admin
Cache empty during outage	No pre-warming	Implement cache warming job
