Intercom Webhooks Events

What it does

When your agent uses it

• Setting up webhook endpoints
• Processing Intercom notifications
• Submitting custom data events for contact activity tracking
• With phrases like intercom webhook

Example prompts

• “intercom webhook”
• “intercom events”
• “intercom webhook signature”
• “/intercom-webhooks-events”

Requirements

• A credential in INTERCOM_WEBHOOK_SECRET
• A credential in INTERCOM_ACCESS_TOKEN
• Compatibility (from SKILL.md): Designed for Claude Code
• Pre-approved tools (allowed-tools): Read, Write, Edit, Bash(curl:*)

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Build the signed endpoint. Create an Express route that captures the raw body (express.raw), verifies the X-Hub-Signature HMAC-SHA1 digest…
2. 2Model the payload. Every delivery is a notification_event envelope carrying topic, id, and data.item (the changed resource). Type it so…
3. 3Route by topic. Dispatch on notification.topic through a handler map; log and no-op unknown topics rather than throwing. Pick topics from…
4. 4Add idempotency. Intercom retries a failed delivery once after ~1 minute. Guard each notification.id with a Redis SET NX lock so retries…
5. 5Track outbound events. Submit custom activity with client.dataEvents.create using a past-tense verb-noun eventName, a Unix createdAt, the…
6. 6Submit in bulk when needed. There is no batch events endpoint — throttle individual dataEvents.create calls (e.g. a short delay every 50)…

What it can do on your machine

Read from SKILL.md and the folder at commit 80f86df. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Read
  • Write
  • Edit
  • Bash(curl:*)

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Links to these hosts (documentation or services it may open):

  • developers.intercom.com

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names these keys or tokens, usually read from environment variables:

  • INTERCOM_WEBHOOK_SECRET
  • INTERCOM_ACCESS_TOKEN

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

• Compatibility

  Designed for Claude Code

  From compatibility in the SKILL.md frontmatter.

Context cost

Intercom Webhooks Events loads about 1.6k tokens when it runs, and up to ~3.6k if it reads all its reference files. Until then it costs about 98 tokens; SKILL.md has 583 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~98

When it runs · the whole SKILL.md, loaded when a task matches

~1.6k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~3.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
