evoGo - Evolution API Go v3

Complete WhatsApp automation via Evolution API Go v3. Send messages, manage groups, automate conversations, and integrate webhooks.

🚀 Quick Start

1. Set Environment Variables

{
  env: {
    EVOGO_API_URL: "http://localhost:8080",        // Your API URL
    EVOGO_GLOBAL_KEY: "your-global-admin-key",     // Admin key (instance mgmt)
    EVOGO_INSTANCE: "my-bot",                      // Instance name
    EVOGO_API_KEY: "your-instance-token"           // Instance token (messaging)
  }
}

2. Create Instance & Connect

# Create instance
curl -X POST "$EVOGO_API_URL/instance/create" \
  -H "apikey: $EVOGO_GLOBAL_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "my-bot",
    "token": "my-secret-token",
    "qrcode": true
  }'

# Connect & get QR code
curl -X POST "$EVOGO_API_URL/instance/connect" \
  -H "apikey: $EVOGO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"number": ""}'

Scan the QR code returned in qrcode.base64.

3. Send First Message

curl -X POST "$EVOGO_API_URL/send/text" \
  -H "apikey: $EVOGO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "number": "5511999999999",
    "text": "Hello from evoGo! 🚀"
  }'

🔐 Authentication

Two authentication levels:

Type	Header	Usage
Global API Key	`apikey: xxx`	Admin: create/delete instances, logs
Instance Token	`apikey: xxx`	Messaging: send messages, groups, contacts

Set via environment or pass directly in headers.

📦 Core Concepts

Add delay (milliseconds) to avoid rate limits:

{

  "text": "Message with delay",
  "delay": 2000
}

⚠️ 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:

Error	Solution
Instance not connected	Run `POST /instance/connect`
Invalid phone format	Use international without `+`: `5511999999999`
Message not sent	Check `GET /instance/status`
Group operation failed	Verify you're admin (for admin operations)

🔗 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

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

Group Operations Failing

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

📚 Resources

Evolution API Go: https://github.com/EvolutionAPI/evolution-api
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

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