Post Sentry Issue Blast-Radius From Linked Intercom Reports

What it does

When a Sentry issue spikes, it pulls all Intercom conversations whose error fingerprint maps to that issue, builds a blast-radius picture (how many customers, which accounts, first and latest report), and drops a single Slack message so engineering and support share one view of who is impacted.

When to use it

Use it during incidents or noisy regressions when leadership keeps asking "how many customers does this actually affect?" and the answer is scattered across Intercom threads and Sentry counts.

How it works

  1. 1A Sentry alert fires when an issue's event rate crosses your threshold.
  2. 2Intercom is queried for open conversations matching the issue's fingerprint.
  3. 3A logic step aggregates affected customers, account tiers, and report timestamps.
  4. 4An OpenAI step writes a concise blast-radius summary.
  5. 5The summary is posted to a Slack incident channel with deep links to Sentry and the Intercom threads.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect SentryErrors, performance, releases.
  2. 2
    Connect IntercomConversations, contacts, articles.
  3. 3
    Connect OpenAIModels, embeddings, files.
  4. 4
    Connect SlackChannels, DMs, threads, mentions.
  5. 5
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  6. 6
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  7. 7
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
