Breaking Changes

• v6
  • For REST mode, you need to run <binary> rest instead of <binary>
    • for example: ./whatsapp rest instead of ./whatsapp
  • For MCP mode, you need to run <binary> mcp
    • for example: ./whatsapp mcp
• v7
  • Starting version 7.x we are using goreleaser to build the binary, so you can download the binary from release
• v8

  • Multi-device support: You can now connect and manage multiple WhatsApp accounts simultaneously in a single server instance

  • New Device Management API: New endpoints under /devices for managing multiple devices

  • Device scoping required: All device-scoped REST API calls now require either:

    • X-Device-Id header, or
    • device_id query parameter
    • If only one device is registered, it will be used as the default

  • WebSocket device scoping: Connect to /ws?device_id=<id> to scope WebSocket to a specific device

  • Webhook payload changes: All webhook payloads now include a top-level device_id field identifying which device received the event:

    ```json
    {
      "event": "message",
      "device_id": "628123456789@s.whatsapp.net",
      "payload": { ... }
    }
    ```
    

Feature

• Send WhatsApp message via http API, docs/openapi.yml for more details

• MCP (Model Context Protocol) Server Support - Integrate with AI agents and tools using standardized protocol

• Mention someone

  • @phoneNumber
  • example: Hello @628974812XXXX, @628974812XXXX

• Ghost Mentions (Mention All) - Mention group participants without showing @phone in message text

  • Pass phone numbers in mentions field to mention users without visible @ in message
  • Use special keyword @everyone to automatically mention ALL group participants
  • UI checkbox available in Send Message modal for groups

• Post Whatsapp Status

• Send Stickers - Automatically converts images to WebP sticker format

  • Supports JPG, JPEG, PNG, WebP, and GIF formats
  • Automatic resizing to 512x512 pixels
  • Preserves transparency for PNG images
  • Animated WebP stickers are supported but must meet WhatsApp requirements:
    • Must be exactly 512x512 pixels
    • Must be under 500KB file size
    • Maximum 10 seconds duration
    • If your animated sticker doesn't meet these requirements, please resize it before uploading using tools like ezgif.com

• Compress image before send

• Compress video before send

• Change OS name become your app (it's the device name when connect via mobile)

  • --os=Chrome or --os=MyApplication

• Basic Auth (able to add multi credentials)

  • --basic-auth=kemal:secret,toni:password,userName:secretPassword, or you can simplify
  • -b=kemal:secret,toni:password,userName:secretPassword

• Subpath deployment support

  • --base-path="/gowa" (allows deployment under a specific path like /gowa/sub/path)

• Customizable port and debug mode

• Configurable presence on connect

  • --presence-on-connect=unavailable or WHATSAPP_PRESENCE_ON_CONNECT=unavailable
  • available — mark as online (suppresses phone notifications)
  • unavailable — register pushname without going online (default, preserves phone notifications)
  • none — skip presence entirely (pushname won't be registered, contacts may see "-" as name)

• Webhook for received message

  • --webhook="http://yourwebhook.site/handler", or you can simplify
  • -w="http://yourwebhook.site/handler"
  • for more detail, see Webhook Payload Documentation

• Webhook Secret Our webhook will be sent to you with an HMAC header and a sha256 default key secret.

  You may modify this by using the option below:

  • --webhook-secret="secret"

• Webhook Payload Documentation For detailed webhook payload schemas, security implementation, and integration examples, see Webhook Payload Documentation

• Webhook Event Filtering You can filter which events are forwarded to your webhook using:

  • --webhook-events="message,message.ack" (comma-separated list)
  • Or environment variable: WHATSAPP_WEBHOOK_EVENTS=message,message.ack

  Available Webhook Events:

  Event	Description
  message	Text, media, contact, location messages
  message.reaction	Emoji reactions to messages
  message.revoked	Deleted/revoked messages
  message.edited	Edited messages
  message.ack	Delivery and read receipts
  message.deleted	Messages deleted for the user
  group.participants	Group member join/leave/promote/demote events
  group.joined	You were added to a group
  newsletter.joined	You subscribed to a newsletter/channel
  newsletter.left	You unsubscribed from a newsletter
  newsletter.message	New message(s) posted in a newsletter
  newsletter.mute	Newsletter mute setting changed
  call.offer	Incoming call received

  If not configured (empty), all events will be forwarded.

• Webhook TLS Configuration

  If you encounter TLS certificate verification errors when using webhooks (e.g., with Cloudflare tunnels or self-signed certificates):

  tls: failed to verify certificate: x509: certificate signed by unknown authority
  

  You can disable TLS certificate verification using:

  • --webhook-insecure-skip-verify=true
  • Or environment variable: WHATSAPP_WEBHOOK_INSECURE_SKIP_VERIFY=true

  Security Warning: This option disables TLS certificate verification and should only be used in:

  • Development/testing environments
  • Cloudflare tunnels (which provide their own security layer)
  • Internal networks with self-signed certificates

  For production environments, it's strongly recommended to use proper SSL certificates (e.g., Let's Encrypt) instead of disabling verification.

Configuration

You can configure the application using either command-line flags (shown above) or environment variables. Configuration can be set in three ways (in order of priority):

1. Command-line flags (highest priority)
2. Environment variables
3. .env file (lowest priority)

Environment Variables

You can configure the application using environment variables. Configuration can be set in three ways (in order of priority):

1. Command-line flags (highest priority)
2. Environment variables
3. .env file (lowest priority)

To use environment variables:

1. Copy .env.example to .env in your project root (cp src/.env.example src/.env)
2. Modify the values in .env according to your needs
3. Or set the same variables as system environment variables

Available Environment Variables

Documentation:

• For detailed webhook payload schemas, security implementation, and integration examples, see Webhook Payload Documentation
• For comprehensive Chatwoot integration guide, see Chatwoot Integration Documentation

Note: Command-line flags will override any values set in environment variables or .env file.

• For more command ./whatsapp --help

Requirements

System Requirements

• Go 1.24.0 or higher (for building from source)
• FFmpeg (for media processing)

Platform Support

• Linux (x86_64, ARM64)
• macOS (Intel, Apple Silicon)
• Windows (x86_64) - WSL recommended

Dependencies (without docker)

• Mac OS:
  • brew install ffmpeg webp
  • export CGO_CFLAGS_ALLOW="-Xpreprocessor"
• Linux:
  • sudo apt update
  • sudo apt install ffmpeg webp
• Windows (not recommended, prefer using WSL):
  • Install ffmpeg: download here
