NOWEB

Overview

NOWEB engine does not require a browser to work with WhatsApp Web, it does so directly using a WebSocket. Not running Chromium saves you CPU and Memory, so you can run more instances on a single server!

Run NOWEB

# Core
docker run -it -e "WHATSAPP_DEFAULT_ENGINE=NOWEB" devlikeapro/waha

# Plus
docker run -v `pwd`/.sessions:/app/.sessions -e "WHATSAPP_DEFAULT_ENGINE=NOWEB" devlikeapro/waha-plus

Store

By default, NOWEB doesn’t store any contacts, chats, or messages, so it’s your application’s responsibility to store them. It’s fine for CRM cases like “appointment reminders” or “order notifications” where you don’t need to store the chat history.

These endpoints doesn’t work by default in NOWEB engine.

Here’s how you can enable the store feature:

Enable store

If you want to get the contacts, chats or messages you need to enable it explicitly by settings additional fields in config at POST /api/sessions/start body.

👉 Do not change the values after you scanned QR, it can lead to the loss of the chat history.

{
  "name": "default",
  "config": {
    "noweb": {
      "store": {
        "enabled": true,
        "fullSync": false
      }
    }
  }
}
  • config.noweb.enabled.store=true - to enable the store feature (false by default)
  • config.noweb.enabled.fullSync=true - emulate a desktop connection (and receive more message history).
    • fullSync=false you’ll get about 3 months of message history.
    • fullSync=true you’ll get about 1 year of message history (max 100K messages per chat).

Or enable it on WAHA Dashboard when starting a new session:

Get messages

When you enabled store - you can Get messages from chat, it’s the store with some additional fields in _data:

  • reactions - reactions to the message
  • pollUpdates - encrypted votes to the polls (not decrypted yet, please create an issue if you wish to get the summary of polls in the response.
  • userReceipt - broadcast and group messages - the user receipt of the message (aka ACK flag, green checkmarks) for

Get chats and contacts

When you enabled store - you can Get all chats and Get all contacts.

Here’s some ids you can meet there:

  • 123123123@c.us Phone numbers accounts - international phone number without + at the start and add @c.us at the end. For phone number 12132132131 the chatId is 12132132131@c.us (@s.whatsapp.net can also appear in internal data, simply convert it to @g.us).
  • 12312312123133@g.us - Groups uses random number with @g.us at the end.
  • 123123123@lid - is a hidden user ID, each user has a regular ID along with a hidden one. WhatsApp added that type of ID along with communities functionality.
  • 123123123@newsletter - for 📰 WhatsApp Channels.

Store under the hood

Under the hood, the NOWEB stores the session data in database based on 🗄️ Storage you choose - either in files or in MongoDB.

  • For File local storage it creates sqlite3 database at .sessions/noweb/{sessionName}/store.sqlite3 store with chats, contacts, messages tables with proper indexes.
    • 👉 We don’t recommend opening it manually when the session is running, even for reading, it can lead to the loss of the chat history.
  • For MongoDB in waha_{engine}_{sessionName} it creates chats, contacts, messages collections with proper indexes.
    • 👉 You can safely READ from the database, but DO NOT WRITE to it manually, it can lead to the loss of the chat history.
