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

json5

{
  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

bash

# 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

bash

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! 🚀"
  }'

Type	Header	Usage
Global API Key	`apikey: $EVO_GLOBAL_KEY`	Admin: create/delete instances, fetch all
Instance API Key	`apikey: $EVO_API_KEY`	Messaging, groups, chat, profile, labels

All instance endpoints use the path pattern: /{resource}/{action}/{instanceName}

Rate Limits & Best Practices

Delays

Always add delays between messages:

json

{ "delay": 1200 }

Recommended:

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

Error Handling

Status	Meaning
`200`	Success
`400`	Bad request (check body/params)
`401`	Unauthorized (check API key)
`404`	Not found (instance/resource)
`500`	Server error

Common Issues

Error	Solution
Instance not connected	Run `GET /instance/connect/{instance}`
Invalid phone format	Use country code without `+`: `5511999999999`
Message not sent	Check `GET /instance/connectionState/{instance}`
Group operation failed	Verify you're admin
Media extraction fails	Ensure MongoDB/file storage is enabled
Chatwoot not syncing	Check token and URL, verify `importMessages` is true

Troubleshooting

Instance Won't Connect

bash

# 1. Check instances
GET /instance/fetchInstances

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

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

Chatbot Not Responding

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

Messages Not Being Delivered

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

Lists/Buttons	Supported	Deprecated
PTV (Round Video)	Supported	Supported
Status/Stories	Supported	Supported
Templates	Business Cloud API	Business Cloud API

Tips

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