Intercom Upgrade & Migration
Overview
Upgrade the intercom-client npm package and handle Intercom API version
changes without breaking production traffic. The v6 TypeScript rewrite changed
the API surface — most notably unifying users/leads into a single contacts
API — so this skill drives a branch-based, type-checked upgrade that surfaces
every breaking change through the compiler and test suite before merge.
Deep material lives in references/ so this file stays scannable:
- Full v5 → v6 migration guide — every changed operation with before/after code, API-version pinning, the upgrade procedure, type-import changes, and the method cheat sheet.
- Worked examples — three end-to-end runs from version detection through a committed upgrade branch.
Prerequisites
- A project with
intercom-clientalready installed (npm list intercom-clientshows the current version). - Git available for branch-based upgrades and reviewable diffs.
- A working test suite, ideally including an integration suite that can run against a dev Intercom workspace.
- TypeScript (
tsc) configured if migrating to v6+, since the compiler is the primary breaking-change detector.
Authentication
Intercom API calls authenticate with a workspace access token passed as a Bearer
token. Read it from the INTERCOM_ACCESS_TOKEN environment variable — never
hardcode it. Version-detection curls and the integration test step both consume
this variable:
export INTERCOM_ACCESS_TOKEN="<workspace-access-token>" # from Intercom > Developer Hub
Use a separate dev-workspace token ($DEV_TOKEN) for the integration test step
so the upgrade is validated without touching production data.
Instructions
Follow the workflow at a high level here; drill into the migration guide for the exact code diffs.
Step 1: Check current versions
Read (with the Read tool or npm list) the installed version, the latest
published version, and the live API version to size the upgrade:
npm list intercom-client # installed SDK version
npm view intercom-client version # latest available
curl -s -D - -o /dev/null \
-H "Authorization: Bearer $INTERCOM_ACCESS_TOKEN" \
https://api.intercom.io/me 2>/dev/null | grep -i intercom-version
If the installed major is < 6 and the target is ≥ 6, expect the TypeScript-rewrite breaking changes.
Step 2: Migrate the code (v5 → v6)
For a major crossing, apply the breaking-change diffs with the Edit/Write
tools: swap new Intercom.Client() for new IntercomClient(), move
users/leads calls to the unified contacts API, rename positional params
(id → contactId/conversationId), and update error handling to the
IntercomError instance check. The full before/after set and a one-line-per-method
cheat sheet are in the migration guide.
Step 3: Pin the API version if needed
The SDK sends a compatible Intercom-Version header automatically. Pin it
explicitly only when using raw fetch requests or when a response shape must be
frozen — see the API-version-pinning section of the migration guide.
Step 4: Run the type-checked upgrade on a branch
Do the whole upgrade on a dedicated branch so TypeScript and the tests gate it:
git checkout -b upgrade/intercom-client-v6
npm install intercom-client@latest
npx tsc --noEmit 2>&1 | grep "intercom" # surfaces every breaking change
npm test
Fix each error the compiler reports, re-run until clean, then validate against a dev workspace and commit. The complete procedure is in the migration guide.
Output
Running this skill produces:
- A dedicated upgrade branch (e.g.
upgrade/intercom-client-v6) withintercom-clientbumped inpackage.json/ lockfile. - Source edits that migrate every v5 call site to the v6 API surface.
- A clean
npx tsc --noEmitrun (no remainingintercom-clienttype errors) and a greennpm test/ integration run against a dev workspace. - A commit ready for PR, e.g.
chore: upgrade intercom-client to v6.
Error Handling
| Issue | Detection | Solution |
|-------|-----------|----------|
| Cannot find module 'intercom-client' | Import fails | npm install intercom-client |
| Property 'users' does not exist | TypeScript error | Migrate users/leads to contacts |
| Property 'id' does not exist | Changed param names | Use contactId, conversationId |
| Response shape changed | Runtime errors | Check API version headers, pin Intercom-Version |
| 401 Unauthorized | curl/test fails | Verify INTERCOM_ACCESS_TOKEN is set and valid |
Examples
Quick skeleton — detect, then migrate one call:
npm list intercom-client # e.g. 5.4.0
npm view intercom-client version # e.g. 6.4.0 → major upgrade
// v5 → migrate to → v6
// await client.users.create({ email });
await client.contacts.create({ role: "user", email });
Three full end-to-end runs — version detection, a single-call migration, and a complete branch upgrade — are in references/examples.md.

Next Steps
After the upgrade branch is green, wire the version bump into CI so future
regressions are caught automatically — see the intercom-ci-integration skill
for the pipeline configuration.
