# Notion API Production Deployment Checklist

## Overview

Structured 12-section checklist for deploying Notion API integrations to production. Covers authentication security, capability scoping, page sharing, rate limit compliance, pagination correctness, error handling, API versioning, retry logic, monitoring, graceful degradation, data validation, and OAuth token lifecycle. Each section maps to a specific failure mode observed in production Notion integrations.

This skill produces a verified pass/fail report. Every item is actionable and testable — no aspirational guidance. Full code examples for each section are in [references/code-examples.md](references/code-examples.md).

## Prerequisites

- **Node.js 18+** with `@notionhq/client` v2.x installed
- Working Notion integration tested in a development workspace
- Production Notion API token (internal) or OAuth credentials (public integration)
- Target databases and pages identified by ID
- Deployment platform configured (Vercel, Railway, AWS, etc.)

Verify SDK is installed:

```bash
node -e "const { Client } = require('@notionhq/client'); console.log('SDK loaded')" 2>/dev/null \
  || echo "MISSING: npm install @notionhq/client"
```

## Instructions

Work through each section sequentially. Mark items pass or fail. A single fail in sections 1-6 is a deployment blocker.

---

### Section 1: Token Stored in Environment Variables (Never Hardcoded)

Production tokens must never appear in source code, config files committed to git, or client-side bundles.

- [ ] `NOTION_TOKEN` loaded from environment variable or secret manager (AWS Secrets Manager, GCP Secret Manager, Vault, Vercel env vars)
- [ ] No tokens in source code — verify: `grep -rn "ntn_\|secret_\|NOTION.*=.*ntn" --include="*.ts" --include="*.js" --include="*.env" .`
- [ ] No tokens in git history: `git log -p --all -S "ntn_" -- "*.ts" "*.js" "*.env"`
- [ ] `.env` and `.env.*` files are in `.gitignore`
- [ ] Token rotation procedure documented — who rotates, how to deploy new token without downtime

```typescript
// CORRECT: Token from environment
const notion = new Client({ auth: process.env.NOTION_TOKEN });

// WRONG: Hardcoded token — immediate security incident
const notion = new Client({ auth: 'ntn_R8dkf92jfKLsd9f2...' });
```

**Fail criteria:** Any token found in source, git history, or client bundle.

---

### Section 2: Integration Has Minimum Required Capabilities

Notion integrations request capability scopes at creation time. Production integrations must follow least-privilege.

- [ ] Integration capabilities reviewed at https://www.notion.so/my-integrations
- [ ] Only required capabilities enabled (no "Read user information" unless explicitly needed)
- [ ] "Insert content" vs "Update content" scoped appropriately
- [ ] No "Internal Integration Token" used for public-facing apps (use OAuth instead)

| Capability | Enable if |
|---|---|
| Read content | Reading pages or databases |
| Update content | Modifying existing pages/blocks |
| Insert content | Creating new pages or appending blocks |
| Read comments | Reading page comments |
| Create comments | Adding comments to pages |
| Read user info | Resolving user names/emails (rarely needed) |

**Fail criteria:** Integration has capabilities it does not use in production code paths.

---

### Section 3: All Target Pages/Databases Shared with Integration

The most common production issue: the integration works in dev but fails in prod because pages are not shared.

- [ ] Every database queried via `databases.query()` is shared with the integration
- [ ] Every page retrieved via `pages.retrieve()` is shared with the integration
- [ ] Parent pages for `pages.create()` are shared with the integration
- [ ] Sharing verified programmatically at deploy time (see [access verification script](references/code-examples.md))
- [ ] Sharing verification runs as part of deployment health check (not just once manually)
- [ ] Documented procedure for sharing new pages/databases post-deploy

**Fail criteria:** Any target page or database returns 404 (object_not_found) when accessed by the integration.

---

### Section 4: Rate Limit Handling (3 req/sec, Exponential Backoff)

Notion enforces a hard limit of 3 requests per second per integration. Exceeding this returns HTTP 429.

- [ ] Request rate limited to 3 req/sec maximum using a queue or semaphore
- [ ] Bulk operations use a concurrency limiter (e.g., `p-queue` with `intervalCap: 3, interval: 1000`)
- [ ] No unbounded `Promise.all()` over arrays of API calls
- [ ] Exponential backoff implemented for 429 responses (SDK handles this by default)
- [ ] Backoff caps at a reasonable maximum (e.g., 30 seconds) to avoid infinite waits
- [ ] SDK `@notionhq/client` built-in retry is enabled (default behavior, not explicitly disabled)
- [ ] Monitoring tracks 429 frequency to detect capacity issues

See [rate-limited queue setup](references/code-examples.md) for `p-queue` implementation pattern.

**Fail criteria:** Any code path that can issue more than 3 concurrent requests without queuing.

---

### Section 5: Pagination for All List Endpoints

All Notion list endpoints return paginated results (max 100 items per page). Failing to paginate silently drops data.

- [ ] Every `databases.query()` call handles pagination
- [ ] Every `blocks.children.list()` call handles pagination
- [ ] Every `search()` call handles pagination
- [ ] Every `users.list()` call handles pagination
- [ ] `page_size` explicitly set (default is 100, max is 100)
- [ ] No assumption that results fit in a single page
- [ ] Pagination tested with a database containing >100 items
- [ ] `start_cursor` passed correctly from `next_cursor` (not from offset arithmetic)

See [generic paginator](references/code-examples.md) for a reusable pagination helper.

**Fail criteria:** Any list endpoint that does not loop on `has_more === true`.

---

### Section 6: Error Handling with `isNotionClientError`

The Notion SDK provides `isNotionClientError` for typed error discrimination. Using generic catch blocks loses error context.

- [ ] All Notion API calls use try/catch with `isNotionClientError` for typed handling
- [ ] Error codes handled specifically: `object_not_found`, `validation_error`, `rate_limited`, `unauthorized`, `restricted_resource`, `conflict_error`
- [ ] Errors logged with: error code, request ID (for Notion support), and timestamp
- [ ] User-facing errors do not leak internal IDs or tokens
- [ ] 401 errors trigger immediate alerts (token revoked or expired)
- [ ] 400 validation errors include the full error body in logs
- [ ] Network errors (ECONNREFUSED, ETIMEDOUT) handled separately from API errors

See [typed error handler](references/code-examples.md) for discriminated error handling with `APIErrorCode`.

**Fail criteria:** Any API call with a bare `catch (e) { console.log(e) }` that loses error context.

---

### Section 7: Notion-Version Header Set (2022-06-28)

Notion API responses change between versions. Pinning the version prevents unexpected breaking changes.

- [ ] `notionVersion` explicitly set in Client constructor
- [ ] Version matches the one used during development and testing
- [ ] Current stable version: `2022-06-28`
- [ ] Team aware of Notion API changelog: https://developers.notion.com/changelog

```typescript
const notion = new Client({
  auth: process.env.NOTION_TOKEN,
  notionVersion: '2022-06-28',  // Pin to tested version — do not omit
});
```

- [ ] If using raw HTTP calls, `Notion-Version` header is set explicitly
- [ ] API version upgrade plan documented (test in staging first, then update)

**Fail criteria:** Client created without explicit `notionVersion`, relying on SDK default that may change.

---

### Section 8: Retry Logic for 429/500/503 Responses

The `@notionhq/client` SDK retries automatically, but custom HTTP clients and edge cases need explicit retry logic.

- [ ] SDK default retry behavior verified (not disabled via constructor options)
- [ ] Custom HTTP calls (if any) implement retry for: 429, 500, 502, 503
- [ ] Retry uses exponential backoff: 1s, 2s, 4s, 8s (max 3-5 attempts)
- [ ] `Retry-After` header respected when present on 429 responses
- [ ] Non-retryable errors (400, 401, 403, 404) are NOT retried
- [ ] Circuit breaker considered for sustained 500/503 errors
- [ ] Total retry duration bounded (e.g., max 30s total wait)

See [retry with exponential backoff](references/code-examples.md) for implementation pattern.

**Fail criteria:** Retrying 400/401/404 errors, or no retry on 429/5xx.

---

### Section 9: Monitoring for API Failures

Production Notion integrations must have observability. Silent failures erode data integrity.

- [ ] Structured logging for every Notion API call: method, endpoint, latency, status code, request ID
- [ ] Error rate tracked (target: <1% of requests)
- [ ] Latency percentiles tracked (P50, P95, P99)
- [ ] Alerts configured per severity table below
- [ ] Health check endpoint exposed (e.g., `GET /health/notion`)
- [ ] Monitoring dashboard shows Notion API metrics separately from app metrics
- [ ] On-call runbook references `notion-incident-runbook` skill for triage steps

| Alert | Condition | Severity |
|---|---|---|
| Auth failure | Any 401/403 response | P1 — token may be revoked |
| High error rate | >5% of requests failing in 5min window | P2 |
| Sustained rate limiting | >10 429s in 5min | P2 — review request patterns |
| High latency | P95 > 3000ms over 5min | P3 |
| Notion outage | `status.notion.com` incident or >50% 5xx | P2 — activate fallback |

**Fail criteria:** No alerting on auth failures or sustained errors.

---

### Section 10: Graceful Degradation When Notion Is Down

Notion experiences outages (check https://status.notion.com). The application must not crash when the API is unavailable.

- [ ] Read-heavy endpoints have a cache layer (Redis, in-memory, file-based)
- [ ] Cache TTL set appropriately (e.g., 5-15 minutes for dashboard data)
- [ ] Write operations queue for later retry when Notion is down (dead letter queue or local buffer)
- [ ] Users receive clear feedback: "Data may be stale — Notion is currently unavailable"
- [ ] Application remains functional in degraded mode (serves cached data, disables Notion-dependent features)
- [ ] Cache invalidation strategy documented (how stale can data get?)
- [ ] Feature flags available to disable Notion-dependent features during extended outages

See [cache with fallback](references/code-examples.md) for LRU cache implementation with source tracking.

**Fail criteria:** Application returns 500 to end users when Notion API is unreachable.

---

### Section 11: Data Validation for Property Types

Notion rejects malformed property values with 400 validation errors. Validate before sending.

- [ ] Page title property always provided for `pages.create()` (required by Notion)
- [ ] Select values match existing options in the database schema (Notion rejects unknown options for select, auto-creates for multi-select)
- [ ] Date properties use ISO 8601 format: `2026-04-01` or `2026-04-01T09:00:00.000-05:00`
- [ ] Rich text arrays are never empty — Notion rejects `rich_text: []`
- [ ] Number properties are actual numbers, not strings
- [ ] URL properties contain valid URLs; email properties contain valid email addresses
- [ ] Relation properties reference valid page IDs
- [ ] Property names match the production database schema exactly (case-sensitive)
- [ ] Block content respects Notion limits: 2000 chars per rich text block, 100 blocks per `blocks.children.append()`
- [ ] Input data sanitized before sending (strip control characters, validate UTF-8)

See [property validator](references/code-examples.md) for a validation function that catches common issues.

**Fail criteria:** 400 validation errors occurring in production due to unvalidated property data.

---

### Section 12: OAuth Token Refresh (For Public Integrations)

Public integrations using OAuth must handle token lifecycle. Internal integrations can skip this section.

- [ ] Access tokens stored securely per-workspace (encrypted at rest)
- [ ] Token exchange implemented: authorization code to access token via `POST /v1/oauth/token`
- [ ] `bot_id` and `workspace_id` stored alongside the access token for multi-tenant routing
- [ ] Token revocation handled: if Notion returns 401, prompt user to re-authorize
- [ ] User-initiated disconnect flow removes stored tokens
- [ ] Notion OAuth does NOT use refresh tokens — access tokens are long-lived but can be revoked
- [ ] Re-authorization flow tested: user clicks disconnect, then reconnects
- [ ] OAuth client secret stored in secret manager (not in code or env files)
- [ ] Redirect URI matches exactly what is registered in the Notion integration settings

See [OAuth token exchange](references/code-examples.md) for the authorization code exchange implementation.

**Fail criteria:** OAuth tokens stored in plaintext, or no handling for token revocation (401 responses).

```

## Error Handling

| Scenario | Detection | Response |
|---|---|---|
| Token not in env vars | `process.env.NOTION_TOKEN` is undefined | Abort deploy, log setup instructions |
| Page not shared | 404 `object_not_found` on retrieve | List unshared targets, block deploy |
| Rate limit exceeded | 429 response despite queueing | Reduce concurrency, check for competing integrations |
| Validation error (400) | `isNotionClientError` with `validation_error` | Log full error body, fix property data |
| Auth failure (401) | `isNotionClientError` with `unauthorized` | Alert ops, rotate token, re-deploy |
| Notion outage (5xx) | Multiple 500/502/503 in sequence | Activate cache/fallback mode |
| Property type mismatch | 400 on `pages.create` or `pages.update` | Run property validator, fix schema mapping |
| Pagination missed | Query returns exactly 100 results | Audit code for missing `has_more` loops |
