Zoom Team Chat offers two distinct APIs for different use cases. Choose the right one before you start building.
Pick one of these integration types before writing code:
/v2/chat/users/.../v2/im/chat/messagesMost implementation issues come from mixing user-type auth with bot-type endpoints (or the opposite).
| Use Case | API to Use | Messages Appear As |
|---|---|---|
| Send notifications from scripts/CI/CD | Team Chat API | Authenticated user |
| Automate messages as a user | Team Chat API | Authenticated user |
| Build an interactive chatbot | Chatbot API | Your bot |
| Respond to slash commands | Chatbot API | Your bot |
| Create messages with buttons/forms | Chatbot API | Your bot |
| Handle user interactions | Chatbot API | Your bot |
The Team Chat API allows your application to send messages as an authenticated user. Messages appear in Team Chat as if the user sent them manually.
✅ Use Team Chat API when:
| Aspect | Details |
|---|---|
| Authentication | User OAuth (authorization_code flow) |
| Endpoint | POST https://api.zoom.us/v2/chat/users/me/messages |
| Message Format | Plain text or markdown |
| Scopes | chat_message:write, chat_channel:read |
| User Experience | Messages appear from the authenticated user |
CI/CD Notifications
User: "Build #123 completed successfully"Automated Reporting
User: "Daily sales report: $10,000"Task Reminders
User: "Reminder: Team meeting in 15 minutes"The Chatbot API allows your application to send messages as a bot. Bots can send rich, interactive messages with buttons, forms, images, and handle user interactions via webhooks.
✅ Use Chatbot API when:
/weather)| Aspect | Details |
|---|---|
| Authentication | Client Credentials grant |
| Endpoint | POST https://api.zoom.us/v2/im/chat/messages |
| Message Format | Rich cards with components |
| Scopes | imchat:bot (auto-added) |
| User Experience | Messages appear from your bot |
| Interactivity | Buttons, forms, dropdowns, webhooks |

Flow: authorization_code
Requires: User login and consent
Token Scope: User’s data only
// Step 1: Redirect user to OAuth consent page
const authUrl = `https://zoom.us/oauth/authorize?response_type=code&client_id=${CLIENT_ID}&redirect_uri=${REDIRECT_URI}`;
// Step 2: Exchange auth code for access token
const tokens = await exchangeCodeForToken(code);
// Step 3: Use access token to send messages
fetch('https://api.zoom.us/v2/chat/users/me/messages', {
headers: { 'Authorization': `Bearer ${tokens.access_token}` }
});Flow: client_credentials
Requires: No user login
Token Scope: Bot actions only
// Step 1: Get bot token (no user interaction)
const credentials = Buffer.from(`${CLIENT_ID}:${CLIENT_SECRET}`).toString('base64');
const response = await fetch('https://zoom.us/oauth/token', {
method: 'POST',
headers: { 'Authorization': `Basic ${credentials}` },
body: 'grant_type=client_credentials'
});
const { access_token } = await response.json();
// Step 2: Use access token to send bot messages
fetch('https://api.zoom.us/v2/im/chat/messages', {
headers: { 'Authorization': `Bearer ${access_token}` }
});Yes! You can use both APIs in the same application.
Example: Task management app
Need rich interactive messages?
├─ Yes → Chatbot API
└─ No
└─ Need webhooks (slash commands, button clicks)?
├─ Yes → Chatbot API
└─ No
└─ Messages should appear as user?
├─ Yes → Team Chat API
└─ No → Chatbot APIReality: Chatbots require General App (OAuth), not Server-to-Server OAuth. S2S apps don’t support the Chatbot feature.
Reality: Only Chatbot API supports interactive components (buttons, forms, dropdowns).
Reality: Chatbot API uses client_credentials flow (no user login needed).
Reality: Use https://zoom.us/oauth/token for token exchange. Keep https://zoom.us/oauth/authorize for the user consent step.
Reality: You can use both APIs in the same application.
