Zoom REST API

Expert guidance for building server-side integrations with the Zoom REST API. This API provides 600+ endpoints for managing meetings, users, webinars, recordings, reports, and all Zoom platform resources programmatically.

Quick Links

New to Zoom REST API? Follow this path:

1. API Architecture - Base URLs, regional URLs, me keyword, ID vs UUID, time formats
2. Authentication Flows - OAuth setup (S2S, User, PKCE, Device Code)
3. Meeting URLs vs Meeting SDK - Stop mixing join_url with Meeting SDK
4. Meeting Lifecycle - Create → Update → Start → End → Delete with webhooks
5. Rate Limiting Strategy - Plan tiers, per-user limits, retry patterns

Reference:

• Meetings - Meeting CRUD, types, settings
• Users - User provisioning and management
• Recordings - Cloud recording access and download
• AI Services - Scribe endpoint inventory and current AI Services path surface
• GraphQL Queries - Alternative query API (beta)
• Integrated Index - see the section below in this file

Most domain files under references/ are aligned to the official API Hub endpoints.json inventories. Treat those files as the local source of truth for method/path discovery.

Having issues?

• Start with preflight checks → 5-Minute Runbook
• 401 Unauthorized → Authentication Flows (check token expiry, scopes)
• 429 Too Many Requests → Rate Limiting Strategy
• Error codes → Common Errors
• Pagination confusion → Common Issues
• Webhooks not arriving → Webhook Server
• Forum-derived FAQs → Forum Top Questions
• Token/scope failures → Token + Scope Playbook

Building event-driven integrations?

• Webhook Server - Express.js server with CRC validation
• Recording Pipeline - Auto-download via webhook events

Quick Start

Get an Access Token (Server-to-Server OAuth)

curl -X POST "https://zoom.us/oauth/token" \
  -H "Authorization: Basic $(echo -n 'CLIENT_ID:CLIENT_SECRET' | base64)" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "grant_type=account_credentials&account_id=ACCOUNT_ID"

Response:

{
  "access_token": "eyJhbGciOiJIUzI1NiJ9...",
  "token_type": "bearer",
  "expires_in": 3600,
  "scope": "meeting:read meeting:write user:read"
}

Create a Meeting

curl -X POST "https://api.zoom.us/v2/users/HOST_USER_ID/meetings" \
  -H "Authorization: Bearer ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "topic": "Team Standup",
    "type": 2,
    "start_time": "2025-03-15T10:00:00Z",
    "duration": 30,
    "settings": {
      "join_before_host": false,
      "waiting_room": true
    }
  }'

For S2S OAuth, use an explicit host user ID or email in the path. Do not use me.

List Users with Pagination

curl "https://api.zoom.us/v2/users?page_size=300&status=active" \
  -H "Authorization: Bearer ACCESS_TOKEN"

Base URL

https://api.zoom.us/v2

Regional Base URLs

The api_url field in OAuth token responses indicates the user's region. Use regional URLs for data residency compliance:

Note: You can always use the global URL https://api.zoom.us regardless of the api_url value.

Key Features

Prerequisites

• Zoom account (Free tier has API access with lower rate limits)
• App registered on Zoom App Marketplace
• OAuth credentials (Server-to-Server OAuth or User OAuth)
• Appropriate scopes for target endpoints

Critical Gotchas and Best Practices

⚠️ JWT App Type is Deprecated

The JWT app type is deprecated. Migrate to Server-to-Server OAuth. This does NOT affect JWT token signatures used in Video SDK — only the Marketplace "JWT" app type for REST API access.

// OLD (JWT app type - DEPRECATED)
const token = jwt.sign({ iss: apiKey, exp: expiry }, apiSecret);

// NEW (Server-to-Server OAuth)
const token = await getServerToServerToken(accountId, clientId, clientSecret);

⚠️ The me Keyword Rules

• User-level OAuth apps: MUST use me instead of userId (otherwise: invalid token error)
• Server-to-Server OAuth apps: MUST NOT use me — provide the actual userId or email
• Account-level OAuth apps: Can use either me or userId

⚠️ Meeting ID vs UUID — Double Encoding

UUIDs that begin with / or contain // must be double URL-encoded:

// UUID: /abc==
// Single encode: %2Fabc%3D%3D
// Double encode: %252Fabc%253D%253D  ← USE THIS

const uuid = '/abc==';
const encoded = encodeURIComponent(encodeURIComponent(uuid));
const url = `https://api.zoom.us/v2/meetings/${encoded}`;

⚠️ Time Formats

• yyyy-MM-ddTHH:mm:ssZ — UTC time (note the Z suffix)
• yyyy-MM-ddTHH:mm:ss — Local time (no Z, uses timezone field)
• Some report APIs only accept UTC. Check the API reference for each endpoint.

⚠️ Rate Limits Are Per-Account, Not Per-App

All apps on the same Zoom account share rate limits. One heavy app can impact others. Monitor X-RateLimit-Remaining headers proactively.

⚠️ Per-User Daily Limits

Meeting/Webinar create/update operations are limited to 100 per day per user (resets at 00:00 UTC). Distribute operations across different host users when doing bulk operations.

⚠️ Download URLs Require Auth and Follow Redirects

Recording download_url values require Bearer token authentication and may redirect. Always follow redirects:

curl -L -H "Authorization: Bearer ACCESS_TOKEN" "https://zoom.us/rec/download/..."

Use Webhooks Instead of Polling

// DON'T: Poll every minute (wastes API quota)
setInterval(() => getMeetings(), 60000);

// DO: Receive webhook events in real-time
app.post('/webhook', (req, res) => {
  if (req.body.event === 'meeting.started') {
    handleMeetingStarted(req.body.payload);
  }
  res.status(200).send();
});

Most Critical Documents

1. API Architecture (FOUNDATION)

concepts/api-architecture.md

Essential knowledge before making any API call:

• Base URLs and regional endpoints
• The me keyword rules (different per app type!)
• Meeting ID vs UUID double-encoding
• ISO 8601 time formats (UTC vs local)
• Download URL authentication

2. Rate Limiting Strategy (MOST COMMON PRODUCTION ISSUE)

concepts/rate-limiting-strategy.md

Rate limits are per-account, shared across all apps:

• Free: 4/sec Light, 2/sec Medium, 1/sec Heavy
• Pro: 30/sec Light, 20/sec Medium, 10/sec Heavy
• Business+: 80/sec Light, 60/sec Medium, 40/sec Heavy
• Per-user: 100 meeting create/update per day

3. Meeting Lifecycle (MOST COMMON TASK)

examples/meeting-lifecycle.md

Complete CRUD with webhook integration — the pattern most developers need first.

Key Learnings

Critical Discoveries:

1. JWT app type is deprecated — use Server-to-Server OAuth

   • The JWT app type on Marketplace is deprecated, NOT JWT token signatures
   • See: Authentication Flows

2. me keyword behaves differently by app type

   • User OAuth: MUST use me
   • S2S OAuth: MUST NOT use me
   • See: API Architecture

3. Rate limiting is nuanced (don’t assume a single global rule)

   • Limits can vary by endpoint and may be enforced at account/app/user levels
   • Treat quotas as potentially shared across your account and implement backoff
   • Monitor rate limit response headers (for example X-RateLimit-Remaining)
   • See: Rate Limiting Strategy

4. 100 meeting creates per user per day

   • This is a hard per-user limit, not related to rate limits
   • Distribute across host users for bulk operations
   • See: Rate Limiting Strategy

5. UUID double-encoding is required for certain UUIDs

   • UUIDs starting with / or containing // must be double-encoded
   • See: API Architecture

6. Pagination: use next_page_token, not page_number

   • page_number is legacy and being phased out
   • next_page_token is the recommended approach
   • See: Common Issues

7. GraphQL is at /v3/graphql, not /v2/

   • Single endpoint, cursor-based pagination
   • Rate limits apply per-field (each field = one REST equivalent)
   • See: GraphQL Queries

Quick Reference

"401 Unauthorized"

→ Authentication Flows - Token expired or wrong scopes

"429 Too Many Requests"

→ Rate Limiting Strategy - Check headers for reset time

"Invalid token" when using userId

→ API Architecture - User OAuth apps must use me

"How do I paginate results?"

→ Common Issues - Use next_page_token

"Webhooks not arriving"

→ Webhook Server - CRC validation required

"Recording download fails"

→ Recording Pipeline - Bearer auth + follow redirects

"How do I create a meeting?"

→ Meeting Lifecycle - Full working examples
