⚠️ Rate Limits & Best Practices

Delays

Always add delays between messages:

{"delay": 2000}  // 2 seconds

Recommended:

• 1-2 seconds between individual messages
• 3-5 seconds between mass sends
• Exponential backoff on errors

Error Handling

HTTP Status Codes:

• 200 - Success
• 400 - Bad request (check parameters)
• 401 - Unauthorized (check API key)
• 404 - Not found (instance/resource doesn't exist)
• 500 - Server error

Common Issues:

---

🔗 Webhooks

Configure webhooks to receive real-time events:

• Message received
• Message sent
• Connection status
• Group updates
• Calls received
• And more...

Use POST /webhook/set endpoint to configure webhook URL (see Postman collection for details).

---

🧪 Troubleshooting

Instance Won't Connect

# 1. Check if instance exists
GET /instance/all

# 2. Force reconnect
POST /instance/forcereconnect/{instance}

# 3. Check logs
GET /instance/logs/{instance}?level=error

Messages Not Sending

1. Verify connection: GET /instance/status
2. Check phone format (no + or spaces)
3. Ensure recipient has WhatsApp
4. Verify API key is correct

Group Operations Failing

1. Check you're admin (for admin operations)
2. Verify group JID format: xxxxx@g.us
3. Ensure participants use format: number@s.whatsapp.net

• WhatsApp Business API: https://developers.facebook.com/docs/whatsapp
• JID Format Guide: number@s.whatsapp.net for users, xxxxx@g.us for groups

---

🆕 Known Limitations

Not Working (v3.0):

• /send/button - Interactive buttons (deprecated by WhatsApp)
• /send/list - Interactive lists (deprecated by WhatsApp)

These endpoints exist but are non-functional due to WhatsApp API changes.

---

💡 Tips

1. Always check status before operations
2. Use delays to avoid rate limits (1-2s minimum)
3. Store tokens securely in environment variables
4. Handle disconnects with automatic reconnection
5. Validate numbers before sending
6. Use webhooks for real-time event handling
7. Monitor logs for troubleshooting
8. Test with small groups before mass operations
