Evolution API v2.3

Complete WhatsApp automation via Evolution API v2.3. Send messages, manage groups, integrate chatbots (Typebot, OpenAI, Dify, Flowise, N8N, Evo AI), configure webhooks, and connect with Chatwoot.

Quick Start

1. Set Environment Variables

{
  env: {
    EVO_API_URL: "http://localhost:8080",       // Your API URL
    EVO_GLOBAL_KEY: "your-global-admin-key",    // Admin key (instance mgmt)
    EVO_INSTANCE: "my-bot",                     // Instance name
    EVO_API_KEY: "your-instance-token"          // Instance token (messaging)
  }
}

2. Create Instance & Connect

# Create instance (supports Baileys, Business, or Evolution integration)
curl -X POST "$EVO_API_URL/instance/create" \
  -H "apikey: $EVO_GLOBAL_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "instanceName": "my-bot",
    "qrcode": true,
    "integration": "WHATSAPP-BAILEYS"
  }'

# Connect & get QR code
curl -X GET "$EVO_API_URL/instance/connect/$EVO_INSTANCE" \
  -H "apikey: $EVO_API_KEY"

Scan the QR code returned in base64 field. Alternately pass ?number=5511999999999 for pairing code.

3. Send First Message

curl -X POST "$EVO_API_URL/message/sendText/$EVO_INSTANCE" \
  -H "apikey: $EVO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "number": "5511999999999",
    "text": "Hello from Evolution API v2! 🚀"
  }'

Rate Limits & Best Practices

Delays

Always add delays between messages:

{ "delay": 1200 }

Recommended:

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

Error Handling

Common Issues

Troubleshooting

Instance Won't Connect

# 1. Check instances
GET /instance/fetchInstances

# 2. Restart instance
POST /instance/restart/{instance}

# 3. Reconnect
GET /instance/connect/{instance}

Chatbot Not Responding

1. Check bot is enabled: GET /{botType}/find/{instance}
2. Check trigger matches incoming message
3. Check session status: GET /{botType}/fetchSessions/{botId}/{instance}
4. Reset session: POST /{botType}/changeStatus/{instance} with status: "closed"

Messages Not Being Delivered

1. Verify connection: GET /instance/connectionState/{instance}
2. Check phone format (no +, no spaces)
3. Verify recipient has WhatsApp: POST /chat/whatsappNumbers/{instance}
4. Check webhook for delivery status events

v2 vs v3 (Evolution Go) Differences

Resources

• Evolution API: https://github.com/EvolutionAPI/evolution-api
• Documentation: https://doc.evolution-api.com
• Chatwoot: https://www.chatwoot.com
• Typebot: https://typebot.io
• WhatsApp Business API: https://developers.facebook.com/docs/whatsapp

Tips

1. Always check connection before operations
2. Use delays to avoid rate limits (1.2s+ between messages)
3. Store keys in environment variables, never hardcode
4. Handle disconnects with webhook CONNECTION_UPDATE event
5. Validate numbers with whatsappNumbers before bulk sends
6. Use debounceTime in chatbots to group fast messages
7. Set ignoreJids: ["@g.us"] in chatbots to ignore group messages
8. Test triggers with triggerType: "keyword" before switching to "all"
9. Monitor sessions - expired sessions stop chatbot responses
10. Use Chatwoot for human handoff from chatbot flows
