Prerequisites

Zoom app created in Marketplace
Client ID and Client Secret
For S2S OAuth: Account ID

Four Authorization Use Cases

Use Case	App Type	Grant Type	Industry Name
Account Authorization	Server-to-Server	`account_credentials`	Client Credentials Grant, M2M, Two-legged OAuth
User Authorization	General	`authorization_code`	Authorization Code Grant, Three-legged OAuth
Device Authorization	General	`urn:ietf:params:oauth:grant-type:device_code`	Device Authorization Grant (RFC 8628)
Client Authorization	General	`client_credentials`	Client Credentials Grant (chatbot-scoped)

Industry Terminology

Term	Meaning
Two-legged OAuth	No user involved (client ↔ server)
Three-legged OAuth	User involved (user ↔ client ↔ server)
M2M	Machine-to-Machine (backend services)
Public client	Can't keep secrets (mobile, SPA) → use PKCE
Confidential client	Can keep secrets (backend servers)
PKCE	Proof Key for Code Exchange (RFC 7636), pronounced "pixy"

Account Authorization (Server-to-Server OAuth)

For backend automation without user interaction.

Request Access Token

bash

POST https://zoom.us/oauth/token?grant_type=account_credentials&account_id={ACCOUNT_ID}

Headers:
Authorization: Basic {Base64(ClientID:ClientSecret)}

Response

json

{
  "access_token": "eyJ...",
  "token_type": "bearer",
  "expires_in": 3600,
  "scope": "user:read:user:admin",
  "api_url": "https://api.zoom.us"
}

Refresh

Access tokens expire after 1 hour. No separate refresh flow - just request a new token.

User Authorization (Authorization Code Flow)

For apps that act on behalf of users.

Step 1: Redirect User to Authorize

https://zoom.us/oauth/authorize?response_type=code&client_id={CLIENT_ID}&redirect_uri={REDIRECT_URI}

Use

https://zoom.us/oauth/authorize

for consent, but

https://zoom.us/oauth/token

for token exchange.

Optional Parameters:

Parameter	Description
`state`	CSRF protection, maintains state through flow
`code_challenge`	For PKCE (see below)
`code_challenge_method`	`S256` or `plain` (default: plain)

Step 2: User Authorizes

User signs in and grants permission

Redirects to

redirect_uri

with authorization code:

https://example.com/?code={AUTHORIZATION_CODE}

Step 3: Exchange Code for Token

bash

POST https://zoom.us/oauth/token?grant_type=authorization_code&code={CODE}&redirect_uri={REDIRECT_URI}

Headers:
Authorization: Basic {Base64(ClientID:ClientSecret)}

With PKCE: Add

code_verifier

parameter.

Response

json

{
  "access_token": "eyJ...",
  "token_type": "bearer",
  "refresh_token": "eyJ...",
  "expires_in": 3600,
  "scope": "user:read:user",
  "api_url": "https://api.zoom.us"
}

Refresh Token

bash

POST https://zoom.us/oauth/token?grant_type=refresh_token&refresh_token={REFRESH_TOKEN}

Headers:
Authorization: Basic {Base64(ClientID:ClientSecret)}

Access tokens expire after 1 hour
Refresh token lifetime can vary; ~90 days is common for some user-based flows. Treat it as configuration/behavior that can change and rely on runtime errors + re-auth fallback.
Always use the latest refresh token for the next request
If refresh token expires, redirect user to authorization URL to restart flow

User-Level vs Account-Level Apps

Type	Who Can Authorize	Scope Access
User-level	Any individual user	Scoped to themselves
Account-level	User with admin permissions	Account-wide access (admin scopes)

Device Authorization (Device Flow)

For devices without browsers (e.g., Meeting SDK apps).

Prerequisites

Enable "Use App on Device" in: Features > Embed > Enable Meeting SDK

Step 1: Request Device Code

bash

POST https://zoom.us/oauth/devicecode?client_id={CLIENT_ID}

Headers:
Authorization: Basic {Base64(ClientID:ClientSecret)}

Response

json

{
  "device_code": "DEVICE_CODE",
  "user_code": "abcd1234",
  "verification_uri": "https://zoom.us/oauth_device",
  "verification_uri_complete": "https://zoom.us/oauth/device/complete/{CODE}",
  "expires_in": 900,
  "interval": 5
}

Step 2: User Authorization

Direct user to:

```
verification_uri
```
and display
```
user_code
```
for manual entry, OR
```
verification_uri_complete
```
(user code prefilled)

User signs in and allows the app.

Step 3: Poll for Token

Poll at the

interval

(5 seconds) until user authorizes:

bash

POST https://zoom.us/oauth/token?grant_type=urn:ietf:params:oauth:grant-type:device_code&device_code={DEVICE_CODE}

Headers:
Authorization: Basic {Base64(ClientID:ClientSecret)}

Response

json

{
  "access_token": "eyJ...",
  "token_type": "bearer",
  "refresh_token": "eyJ...",
  "expires_in": 3599,
  "scope": "user:read:user user:read:token",
  "api_url": "https://api.zoom.us"
}

Polling Responses

Response	Meaning	Action
Token returned	User authorized	Store tokens, done
`error: authorization_pending`	User hasn't authorized yet	Keep polling at interval
`error: slow_down`	Polling too fast	Increase interval by 5 seconds
`error: expired_token`	Device code expired (15 min)	Restart flow from Step 1
`error: access_denied`	User denied authorization	Handle denial, don't retry

Polling Implementation

javascript

async function pollForToken(deviceCode, interval) {
  while (true) {
    await sleep(interval * 1000);
    
    try {
      const response = await axios.post(
        `https://zoom.us/oauth/token?grant_type=urn:ietf:params:oauth:grant-type:device_code&device_code=${deviceCode}`,
        null,
        { headers: { 'Authorization': `Basic ${credentials}` } }
      );
      return response.data; // Success - got tokens
    } catch (error) {
      const err = error.response?.data?.error;
      if (err === 'authorization_pending') continue;
      if (err === 'slow_down') { interval += 5; continue; }
      throw error; // expired_token or access_denied
    }
  }
}

Refresh

Same as User Authorization. If refresh token expires, restart device flow from Step 1.

Client Authorization (Chatbot)

For chatbot message operations only.

Request Token

bash

POST https://zoom.us/oauth/token?grant_type=client_credentials

Headers:
Authorization: Basic {Base64(ClientID:ClientSecret)}

Response

json

{
  "access_token": "eyJ...",
  "token_type": "bearer",
  "expires_in": 3600,
  "scope": "imchat:bot",
  "api_url": "https://api.zoom.us"
}

Refresh

Tokens expire after 1 hour. No refresh flow - just request a new token.

Using Access Tokens

Call API

bash

GET https://api.zoom.us/v2/users/me

Headers:
Authorization: Bearer {ACCESS_TOKEN}

Me Context

Replace

userID

with

me

to target the token's associated user:

Endpoint	Methods
`/v2/users/me`	GET, PATCH
`/v2/users/me/token`	GET
`/v2/users/me/meetings`	GET, POST

Revoke Access Token

Works for all authorization types.

bash

POST https://zoom.us/oauth/revoke?token={ACCESS_TOKEN}

Headers:
Authorization: Basic {Base64(ClientID:ClientSecret)}

Response

json

{
  "status": "success"
}

PKCE (Proof Key for Code Exchange)

For public clients that can't securely store secrets (mobile apps, SPAs, desktop apps).

When to Use PKCE

Client Type	Use PKCE?	Why
Mobile app	Yes	Can't securely store client secret
Single Page App (SPA)	Yes	JavaScript is visible to users
Desktop app	Yes	Binary can be decompiled
Meeting SDK (client-side)	Yes	Runs on user's device
Backend server	Optional	Can keep secrets, but PKCE adds security

How PKCE Works

Implementation (Node.js)

javascript

const crypto = require('crypto');

function generatePKCE() {
  const verifier = crypto.randomBytes(32).toString('base64url');
  const challenge = crypto.createHash('sha256').update(verifier).digest('base64url');
  return { verifier, challenge };
}

const pkce = generatePKCE();

const authUrl = `https://zoom.us/oauth/authorize?` +
  `response_type=code&` +
  `client_id=${CLIENT_ID}&` +
  `redirect_uri=${REDIRECT_URI}&` +
  `code_challenge=${pkce.challenge}&` +
  `code_challenge_method=S256`;

// Store pkce.verifier in session for callback

Token Exchange with PKCE

bash

POST https://zoom.us/oauth/token?grant_type=authorization_code&code={CODE}&redirect_uri={REDIRECT_URI}&code_verifier={VERIFIER}

Headers:
Authorization: Basic {Base64(ClientID:ClientSecret)}

Deauthorization

When a user removes your app, Zoom sends a webhook to your Deauthorization Notification Endpoint URL.

Webhook Event

json

{
  "event": "app_deauthorized",
  "event_ts": 1740439732278,
  "payload": {
    "account_id": "ACCOUNT_ID",
    "user_id": "USER_ID",
    "signature": "SIGNATURE",
    "deauthorization_time": "2019-06-17T13:52:28.632Z",
    "client_id": "CLIENT_ID"
  }
}

Requirements

Delete all associated user data after receiving this event
Verify webhook signature (use secret token, verification token deprecated Oct 2023)
Only public apps receive deauthorization webhooks (not private/dev apps)

Pre-Approval Flow

Some Zoom accounts require Marketplace admin pre-approval before users can authorize apps.

Users can request pre-approval from their admin
Account-level apps (admin scopes) require appropriate role permissions

Active Apps Notifier (AAN)

In-meeting feature showing apps with real-time access to content.

Displays icon + tooltip with app info, content type being accessed, approving account
Supported: Zoom client 5.6.7+, Meeting SDK 5.9.0+

OAuth Scopes

Scope Types

Type	Description	For
Classic scopes	Legacy scopes (user, admin, master levels)	Existing apps
Granular scopes	New fine-grained scopes with optional support	New apps

Classic Scopes

For previously-created apps. Three levels:

User-level: Access to individual user's data
Admin-level: Account-wide access, requires admin role
Master-level: For master-sub account setups, requires account owner

Full list: https://developers.zoom.us/docs/integrations/oauth-scopes/

Granular Scopes

For new apps. Format:

<service>:<action>:<data_claim>:<access>

Component	Values
service	`meeting` , `webinar` , `user` , `recording` , etc.
action	`read` , `write` , `update` , `delete`
data_claim	Data category (e.g., `participants` , `settings` )
access	empty (user), `admin` , `master`

Example:

meeting:read:list_meetings:admin

Full list: https://developers.zoom.us/docs/integrations/oauth-scopes-granular/

Optional Scopes

Granular scopes can be marked as optional - users choose whether to grant them.

Basic authorization (uses build flow defaults):

https://zoom.us/oauth/authorize?response_type=code&client_id={CLIENT_ID}&redirect_uri={REDIRECT_URI}

Advanced authorization (custom scopes per request):

https://zoom.us/oauth/authorize?client_id={CLIENT_ID}&response_type=code&redirect_uri={REDIRECT_URI}&scope={required_scopes}&optional_scope={optional_scopes}

Include previously granted scopes:

https://zoom.us/oauth/authorize?...&include_granted_scopes&scope={additional_scopes}

Migrating Classic to Granular

Manage > select app > edit
Scope page > Development tab > click Migrate
Review auto-assigned granular scopes, remove unnecessary, mark optional
Test
Production tab > click Migrate

Notes:

No review needed if only migrating or reducing scopes
Existing user tokens continue with classic scope values until re-authorization
New users get granular scopes after migration

Common Error Codes

Code	Message	Solution
4700	Token cannot be empty	Check Authorization header has valid token
4702/4704	Invalid client	Verify Client ID and Client Secret
4705	Grant type not supported	Use: `account_credentials` , `authorization_code` , `urn:ietf:params:oauth:grant-type:device_code` , or `client_credentials`
4706	Client ID or secret missing	Add credentials to header or request params
4709	Redirect URI mismatch	Ensure redirect_uri matches app configuration exactly (including trailing slash)
4711	Refresh token invalid	Token scopes don't match client scopes
4717	App has been disabled	Contact Zoom support
4733	Code is expired	Authorization codes expire in 5 minutes - restart flow
4734	Invalid authorization code	Regenerate authorization code
4735	Owner of token does not exist	User was removed from account - re-authorize
4741	Token has been revoked	Use the most recent token from latest authorization

See

references/oauth-errors.md

for complete error list.

Quick Reference

Flow	Grant Type	Token Expiry	Refresh
Account (S2S)	`account_credentials`	1 hour	Request new token
User	`authorization_code`	1 hour	Use refresh_token (90 day expiry)
Device	`urn:ietf:params:oauth:grant-type:device_code`	1 hour	Use refresh_token (90 day expiry)
Client (Chatbot)	`client_credentials`	1 hour	Request new token

Demo Guidance

If you build an OAuth demo app, document its runtime base URL in that demo project's own README or

.env.example

, not in this shared skill.

Quick Start Path

If you're new to Zoom OAuth, follow this order:

Run preflight checks first → RUNBOOK.md
Choose your OAuth flow → concepts/oauth-flows.md
- 4 flows: S2S (backend), User (SaaS), Device (no browser), Chatbot
- Decision matrix: Which flow fits your use case?
Understand token lifecycle → concepts/token-lifecycle.md
- CRITICAL: How tokens expire, refresh, and revoke
- Common pitfalls: refresh token rotation
Implement your flow → Jump to examples:
- Backend automation → examples/s2s-oauth-redis.md
- SaaS app → examples/user-oauth-mysql.md
- Mobile/SPA → examples/pkce-implementation.md
- Device (TV/kiosk) → examples/device-flow.md
Fix redirect URI issues → troubleshooting/redirect-uri-issues.md
- Most common OAuth error: Redirect URI mismatch
Implement token refresh → examples/token-refresh.md
- Automatic middleware pattern
- Handle refresh token rotation
Troubleshoot errors → troubleshooting/common-errors.md
- Error code tables (4700-4741 range)
- Quick diagnostic workflow

By Use Case

I want to automate Zoom tasks on my own account

OAuth Flows - S2S OAuth explained
S2S OAuth Redis - Production pattern with Redis caching
Token Lifecycle - 1hr token, no refresh

I want to build a SaaS app for other Zoom users

OAuth Flows - User OAuth explained
User OAuth MySQL - Production pattern with encryption
Token Refresh - Automatic refresh middleware
Redirect URI Issues - Fix most common error

I want to build a mobile or SPA app

PKCE - Why PKCE is required for public clients
PKCE Implementation - Complete code example
State Parameter - CSRF protection

I want to build an app for devices without browsers (TV, kiosk)

OAuth Flows - Device flow explained
Device Flow Example - Complete polling implementation
Common Errors - Device-specific errors

I'm building a Team Chat bot

OAuth Flows - Chatbot flow explained
S2S OAuth Basic - Similar pattern, different grant type
Scopes Architecture - Chatbot-specific scopes

I'm getting redirect URI errors (4709)

Redirect URI Issues - START HERE!
Common Errors - Error details
User OAuth Basic - See correct pattern

I'm getting token errors (4700-4741)

Token Issues - Diagnostic workflow
Token Lifecycle - Understand expiration
Token Refresh - Implement auto-refresh
Common Errors - Error code tables

I'm getting scope errors (4711)

Scope Issues - Mismatch causes
Scopes Architecture - Classic vs Granular
Classic Scopes - Complete scope reference
Granular Scopes - Granular scope reference

I need to refresh tokens

Token Lifecycle - When to refresh
Token Refresh - Middleware pattern

I need to secure my OAuth implementation

PKCE - Public client security
State Parameter - CSRF protection
User OAuth MySQL - Token encryption at rest

I want to migrate from JWT app to S2S OAuth

S2S OAuth Redis - Modern replacement
Token Lifecycle - Different token behavior

Note: JWT App Type was deprecated in June 2023. Migrate to S2S OAuth for server-to-server automation.

Most Critical Documents

1. OAuth Flows (DECISION DOCUMENT)

concepts/oauth-flows.md

Understand which of the 4 flows to use:

S2S OAuth: Backend automation (your account)
User OAuth: SaaS apps (users authorize you)
Device Flow: Devices without browsers
Chatbot: Team Chat bots only

2. Token Lifecycle (MOST COMMON ISSUE)

concepts/token-lifecycle.md

99% of OAuth issues stem from misunderstanding:

Token expiration (1 hour for all flows)
Refresh token rotation (must save new refresh token)
Revocation behavior (invalidates all tokens)

3. Redirect URI Issues (MOST COMMON ERROR)

troubleshooting/redirect-uri-issues.md

Error 4709 ("Redirect URI mismatch") is the #1 OAuth error. Must match EXACTLY (including trailing slash, http vs https).

Key Learnings

Critical Discoveries:

Refresh Token Rotation
- Each refresh returns a NEW refresh token
- Old refresh token becomes invalid
- Failure to save new token causes 4735 errors
- See: Token Refresh
S2S OAuth Uses Redis, User OAuth Uses Database
- S2S: Single token for entire account → Redis (ephemeral)
- User: Per-user tokens → Database (persistent)
- See: S2S OAuth Redis vs User OAuth MySQL
Redirect URI Must Match EXACTLY
- Trailing slash matters:
```
/callback
```
  ≠
```
/callback/
```
- Protocol matters:
```
http://
```
  ≠
```
https://
```
- Port matters:
```
:3000
```
  ≠
```
:3001
```
- See: Redirect URI Issues
PKCE Required for Public Clients
- Mobile apps CANNOT keep secrets
- SPAs CANNOT keep secrets
- PKCE prevents authorization code interception
- See: PKCE
State Parameter Prevents CSRF
- Generate random state before redirect
- Store in session
- Verify on callback
- See: State Parameter
Token Storage Must Be Encrypted
- NEVER store tokens in plain text
- Use AES-256 minimum
- See: User OAuth MySQL
JWT App Type is Deprecated (June 2023)
- No new JWT apps can be created
- Existing apps still work but will eventually be sunset
- Migrate to S2S OAuth or User OAuth
Scope Levels Determine Authorization Requirements
- No suffix (user-level): Any user can authorize
- ```
:admin
```
  : Requires admin role
- ```
:master
```
  : Requires account owner (multi-account)
- See: Scopes Architecture
Authorization Codes Expire in 5 Minutes
- Exchange code for token immediately
- Don't cache authorization codes
- See: Token Lifecycle
Device Flow Requires Polling
- Poll at interval returned by
```
/devicecode
```
  (usually 5s)
- Handle
```
authorization_pending
```
  ,
```
slow_down
```
  ,
```
expired_token
```
- See: Device Flow
