• Setup wizard + settings integration: HubSpot step in onboarding flow and connections management in settings
• 146 new tests across 10 test files (783 total tests passing)

Architecture

User-Facing Routes (7)          Agent API Routes (11)         Cron
-- oauth/authorize              -- search                     -- hubspot-sync (*/15 * * * *)

-- lists                        -- sync (GET/POST)
-- mappings (GET/PUT)           -- connections
-- sample-data

Database (Migration 026)

• hubspot_connections - Multi-instance, workspace-scoped, OAuth + PAT fields
• hubspot_sync_state - Per-connection per-object-type sync tracking
• hubspot_records - JSONB property cache with GIN index
• hubspot_associations - Association cache

Key Design Decisions

• Dedicated hubspot_connections table over reusing data_sources - HubSpot needs OAuth-specific fields (refresh_token, expires_at)
• Token bucket rate limiter - 50% of HubSpot capacity, priority queue, dynamic adjustment via X-HubSpot-RateLimit-* headers
• Auto-select primary connection - Agent API picks first active connection when connection_id is omitted
• Incremental polling - lastmodifieddate > last_sync_at filter, 90-day backfill on first sync

Files Changed

• 72 new/modified files (+13,290 lines)
• Core library: src/lib/integrations/hubspot/ (8 modules)
• API routes: 18 user-facing + 11 agent endpoints + 1 cron
• UI components: 6 new components
• MCP tools: 14 new tools in packages/mcp-server/
• Signal detectors: 5 new in src/lib/heuristics/signals/detectors/

Test Plan

• Build passes (npm run build)
• 783/783 tests pass (make test)
• 24 curl endpoint tests - all routes correctly reject unauthorized requests with 401
• User-facing routes: 7/7 return 401 without session cookie
• Agent routes: 11/11 return 401 with valid secret but invalid session
• Agent auth: returns 401 with wrong/missing x-agent-secret header
• Cron route: returns 401 without/with-wrong CRON_SECRET
• OAuth flow: requires HubSpot developer app credentials
• Private App token validation: requires live HubSpot portal
• Entity creation chain: requires active HubSpot connection
• Polling sync: requires connected portal with CRM data

• Retry: 3 attempts, 1000ms base exponential backoff

---

Known Limitations

1. No webhook support — Uses polling (every 15 minutes), not real-time webhooks
2. Custom objects read-only — Sync supported but no custom object creation via entity chain
3. OAuth requires HubSpot Developer App — Must register app at developers.hubspot.com
4. Search API limits — HubSpot caps search at 5 req/s and 10,000 results per query
5. Batch size caps — Records: 100 per batch, Associations: 2,000 per batch
6. Sequential sync — Object types sync one-at-a-time per connection (not parallel)
7. No field mapping sync — Mapping config stored but not yet wired into polling engine

Phase 1: Authentication Flow (Browser)

T1.1 — OAuth Flow

• Navigate to /setup → HubSpot step should appear
• Click "Connect with OAuth" → redirects to HubSpot authorization page
• Authorize the app → redirected back to /setup with success state
• Verify connection appears in setup wizard preview (portal name, auth badge)
• Navigate to /settings → HubSpot Connections section shows new connection

T1.2 — Private App Token Flow

• Navigate to /setup → select "Private App" auth method
• Enter a valid Private App token (pat-na1-xxxxx)
• Click validate → connection created with "connected" status
• Verify in settings page

T1.3 — Connection Management

• In /settings → HubSpot section, click "Test Connection" → green success
• Delete a connection → confirmation dialog → connection removed
• Create a second connection (different portal or same with different name)
• Verify primary connection badge assignment

---

Phase 6: Custom Properties (API)

T6.1 — Create Beton Properties

curl -X POST http://localhost:3000/api/agent/hubspot/properties \
  -H "Content-Type: application/json" \
  -H "x-agent-secret: $AGENT_SECRET" \

    "type": "number",
    "field_type": "number",
    "group_name": "beton_scores",
    "description": "Test score from Beton Inspector"
  }'

• Property created in HubSpot
• Verify via properties list endpoint

---

Phase 7: UI Verification (Browser)

T7.1 — Setup Wizard Flow

• Navigate to /setup
• HubSpot step visible at correct position (display_order: 25)
• Can select OAuth or Private App
• Object type checkboxes work (contacts, companies, deals, tickets)
• Skip button works
• Connection preview renders after auth

T7.2 — Settings Page

• /settings shows HubSpot integration card
• HubSpot Connections section lists all connections
• Each connection shows: name, auth type icon (shield/key), portal ID, status badge
• Primary connection has badge indicator
• Test Connection button validates credentials
• Delete button shows confirmation dialog

T7.3 — Field Mapping (if wired)

• Field mapping step renders Beton→HubSpot property mappings
• Auto-create toggle for missing HubSpot properties
• Sample data preview loads from /api/integrations/hubspot/sample-data

---

Phase 8: Signal Detection (After Sync)

T8.1 — Verify Signal Detectors Fire

After syncing data, run signal detection:

curl -X POST http://localhost:3000/api/cron/signal-detection \
  -H "Authorization: Bearer $CRON_SECRET"

• hubspot_new_deal fires for deals created within 7 days
• hubspot_deal_stage_change fires for recently updated deals
• hubspot_ticket_created fires for new tickets
• hubspot_lifecycle_change fires for lifecycle stage changes
• hubspot_meeting_booked fires for meeting engagements
• Signals appear in /signals page
• Account scores updated (health, expansion, churn risk)

---

Phase 9: Error Handling

T9.1 — Invalid Token

• Submit expired/invalid Private App token → clear error message
• Revoke OAuth token in HubSpot → next sync fails gracefully, connection status = 'error'

T9.2 — Rate Limiting

• Rapid-fire 100+ search requests → rate limiter queues, no 429 errors leak to client
• Check rate limiter stats show expected token bucket behavior

T9.3 — Network Errors

• Disconnect HubSpot (invalid URL) → retry logic fires 3x, then error
• Sync lock timeout → auto-releases after 10 minutes

---

Cleanup

After testing, clean up test data:

# Delete test records from HubSpot via API or HubSpot UI
# Remove test connections from Beton settings
# Clear hubspot_records and hubspot_sync_state for test connections

---

Critical

C1. Association arguments swapped in batchCreateChain() (src/lib/integrations/hubspot/entities.ts:441,450)

createAssociation(client, fromType, fromId, toType, toId) is called with swapped IDs:

// Line 441: intends deal->company, but passes deals/{companyId} -> companies/{dealId}
await createAssociation(client, 'deals', companyId, 'companies', dealResult.recordId)
// Line 450: same issue for deal->contact
await createAssociation(client, 'deals', contactId, 'contacts', dealResult.recordId)

Fix:

await createAssociation(client, 'deals', dealResult.recordId, 'companies', companyId)
await createAssociation(client, 'deals', dealResult.recordId, 'contacts', contactId)

This is a data integrity bug -- will create wrong associations in production HubSpot accounts.

Important

I2. PR description says "PKCE" but implementation uses standard code+secret.
Not a code bug -- HubSpot server-side OAuth does not support PKCE. But the PR description should be corrected to avoid confusion.

I3. Signal detectors do not filter by account (all 5 detectors in src/lib/heuristics/signals/detectors/hubspot-*.ts)

All detectors query hubspot_records filtered only by workspace_id and object_type, never joining against the accountId being evaluated. The domain is fetched but never used to filter deals. Result: Every account in a workspace gets identical signals for any deal change. This produces mass false positives.

Fix: Join HubSpot records to accounts via domain/email/company associations, or filter by an account-specific identifier.

I4. meeting_booked detector queries object_type = 'meetings' but meetings are not in STANDARD_OBJECT_TYPES (contacts, companies, deals, tickets). Unless manually added to enabled_objects, this detector will never fire.

I5. Sync lock race condition (polling.ts:66-128)
TOCTOU in acquireSyncLock(): separate select + update allows two processes to both read an expired lock and both take it. Fix: Single atomic UPDATE ... WHERE sync_lock_expires_at < NOW() RETURNING sync_lock_id.

I6. Agent API routes use manual validation instead of Zod
All 11 agent routes do if (!field) checks while MCP tools use Zod schemas. Inconsistent validation means direct agent API calls accept any shape.

I7. GET /api/agent/hubspot/lists is a stub -- returns { message: 'HubSpot lists endpoint active' } instead of actual data.

Minor

• stripNulls utility duplicated in search/route.ts and records/route.ts
• ~25 eslint-disable comments for @typescript-eslint/no-explicit-any (expected until types regenerated)
• is_primary: true set unconditionally in OAuth callback without clearing previous primary
• Rate limiter uses in-memory state -- not shared across Vercel serverless instances (mitigated by 50% capacity)

Positive

• Excellent migration 026 -- all 4 tables have RLS, GIN index on hubspot_records.properties, proper CASCADE deletes, no collision with migration 025
• Strong security -- OAuth tokens encrypted at rest (AES-256-GCM), refresh tokens excluded from API responses, all 11 agent routes validate x-agent-secret, CRON_SECRET verified, OAuth state parameter validated for CSRF prevention
• Thoughtful rate limiter -- token bucket at 50% capacity, priority-based allocation (60/30/10), per-connection state, graceful 429 recovery, Retry-After parsing
• Correct token refresh -- isTokenExpired() uses 5-minute buffer, refreshes BEFORE expiry
• Solid sync engine -- incremental via lastmodifieddate watermark, last_sync_at updated only AFTER success, errors do not advance cursor
• Excellent test coverage -- 14 test files with mock isolation, 146 test cases
• MCP tools are proper thin proxies -- all 14 delegate to agent API, no direct HubSpot calls

Security Checklist

• OAuth tokens encrypted at rest (AES-256-GCM)
• Refresh tokens not in logs or API responses
• All 11 agent routes require x-agent-secret
• No HubSpot API keys in client-side code
• Rate limiter prevents API abuse
• Cron authenticates via CRON_SECRET
• OAuth state parameter validated (CSRF protection)

Verdict

Fix two issues before merge:

1. Swap association arguments in entities.ts:441,450 (2-line fix)
2. Add account-level filtering to all 5 signal detectors (functional correctness)

Then resolve merge conflicts with staging and rename 026_hubspot_integration.sql to 027_hubspot_integration.sql (since PR #66 migration will take the 026 slot).

After those fixes, this is a high-quality PR ready for staging.

Test Report: PR #69 -- HubSpot Integration

Tested by: Claude Code (automated E2E)
Branch: feature/BETON-hubspot-foundation
Preview: beton-inspector-rh3qq9dlg-getbeton.vercel.app

---

Phase 1: Build & Unit Tests

• npm run build -- passes (all pages compile, no TS errors)
• make test -- 783 passing (146 HubSpot-specific)
• make lint + make typecheck -- clean

Phase 2: Bug Fixes

C1: Association arguments swapped -- FIXED

entities.ts:441,450 -- createAssociation had fromId/toId swapped for deal-company and deal-contact associations. Fixed in commit 158fe68.

I3: Signal detectors dont filter by account -- CONFIRMED, NOT FIXED

All 5 hubspot-*.ts detectors query hubspot_records by workspace_id + object_type only. The account domain is fetched but never used as a filter. Every account in a workspace gets signals for ANY deal/meeting change. Recommend fixing before merge -- this will generate false positives at scale.

I4: meeting_booked queries object_type = meetings -- CONFIRMED

hubspot-meeting-booked.ts:42 queries object_type: 'meetings' but the sync only pulls contacts, companies, deals, tickets. Meetings are never synced, so this detector will never fire. Low risk -- it fails silently (returns null).

I7: GET /api/agent/hubspot/lists is a stub -- CONFIRMED

POST works (creates lists, adds contacts). GET returns placeholder message. Functional for agent use (POST is the primary flow), GET can be implemented later.

Phase 3a: Curl Smoke Tests (localhost)

24/24 routes pass -- all return correct auth rejection codes:

• 11 user-facing routes: 401 (no session) or 405 (POST-only on GET)
• 11 agent routes: 401 (no x-agent-secret)
• 1 cron route: 401 (no CRON_SECRET)
• 1 OAuth authorize: 401 (needs session)

No 500s. All route files load and execute without import errors.

Phase 3b: Chrome UI Test

• Settings page renders correctly with auth gate
• HubSpot section hidden when no connections exist (by design -- HubSpotConnectionsSection returns null when empty)
• Migration 026 seeds integration_definitions row for HubSpot -- needs DB migration to appear in category list

Phase 4: Database Migration

Migration 026_hubspot_integration.sql validated:

• 4 tables: hubspot_connections, hubspot_sync_state, hubspot_records, hubspot_associations
• RLS enabled on all 4 with workspace-scoped policies
• GIN index on hubspot_records.properties
• integration_definitions seed row included
• Proper cascading deletes

Phase 5: Vercel Preview

24/24 routes pass on deployed preview -- same results as localhost.

HubSpot Developer App

Created "Beton Inspector" app (ID: 36781241) with OAuth credentials. Env vars pushed to Vercel preview environment.

I7: GET /api/agent/hubspot/lists is a stub -- CONFIRMED
POST works (creates lists, adds contacts). GET returns placeholder. Acceptable for now.

Phase 3: Smoke Tests PASS

Curl -- 24/24 localhost, 24/24 Vercel preview (48 total):

• All user-facing routes: 401 (no session) or 405 (POST-only on GET)
• All agent routes: 401 (no x-agent-secret)
• Cron route: 401 (no CRON_SECRET)
• No 500s anywhere. All route files load without import errors.

Chrome UI -- PASS (with migration applied):

• Settings page renders HubSpot under CRM category with icon + description
• HubSpot card expands to show "Private App Token: Not set" + CONFIGURE button
• HubSpotConnectionsSection renders separately when connections exist (hidden when empty -- by design)
• No console errors, no crashes

Phase 4: Database Migration PASS

Migration 026_hubspot_integration.sql applied to staging and verified:

• 4 tables created: hubspot_connections, hubspot_sync_state, hubspot_records, hubspot_associations
• RLS enabled on all 4 tables with workspace-scoped policies
• GIN index on hubspot_records.properties for JSONB queries
• integration_definitions seed row for HubSpot confirmed (category: crm, display_order: 25)
• Cascading deletes from hubspot_connections working
• Also applied migration 019 (integration_definitions table) which was missing from staging

Phase 5: Vercel Preview PASS

All 24 routes return correct status codes on deployed preview. UI renders correctly with authenticated session after migration applied.

HubSpot Developer App

Created "Beton Inspector" app (ID: 36781241). Env vars (HUBSPOT_CLIENT_ID, HUBSPOT_CLIENT_SECRET, HUBSPOT_APP_ID) pushed to Vercel preview. Only crm.objects.contacts.read scope configured in HubSpot UI -- remaining 6 scopes needed before production OAuth testing.

OAuth E2E Flow -- NOT TESTED

Blocked on: HubSpot app needs remaining 6 OAuth scopes added, and a new Vercel preview deploy is needed to pick up the env vars. The Private App Token flow is testable via the CONFIGURE button now visible in the UI.

I3 Fix Applied: Signal Detector Account Filtering

Commit 85bc5af fixes the correctness issue where all 5 HubSpot signal detectors were firing for every account in a workspace.

What changed (6 files, +121/-11 lines):

• Added getHubSpotIdsForAccount() helper in signals/helpers.ts — bridges Beton accounts to HubSpot records via domain matching + association lookups
• Updated all 5 detectors (hubspot-deal-stage-change, hubspot-new-deal, hubspot-lifecycle-change, hubspot-ticket-created, hubspot-meeting-booked) to scope queries to the specific account

How it works:

1. Fetch account domain from accounts table
2. Find HubSpot company records where properties @> {"domain": "<account_domain>"} (uses GIN index)
3. Resolve associated records via hubspot_associations (checks both directions)
4. Filter hubspot_records query with .in('hubspot_id', matchedIds)

Build passes, 783/783 tests pass.

Closing as superseded by the E5 connector framework (#90) + HubSpot port (#91).

This branch (feature/BETON-hubspot-foundation) predates the field-mapping/DestinationAdapter framework — it's 124 commits behind staging, currently has 12 merge conflicts, and ships the dropped architecture (polling.ts + hubspot_connections/sync_state/records tables). Its 026_hubspot_integration.sql also collides with #91's integration_configs registry migration.

The capability here (incremental sync) will be rebuilt on the SourceAdapter framework rather than ported. See docs/prd-hubspot-pr3-usability.md (WS4).
