GitHub - oxidezap/whatsapp-rust: Whatsapp client written purely in Rust based on whatsmeow and baileys

A high-performance, async Rust library for the WhatsApp Web API. Inspired by whatsmeow (Go) and Baileys (TypeScript).

Documentation | llms.txt | llms-full.txt

Features

• Authentication — QR code pairing, pair code linking, persistent sessions
• Messaging — E2E encrypted (Signal Protocol), 1-on-1 and group chats, editing, reactions, quoting, receipts
• Media — Upload/download images, videos, documents, GIFs, audio with automatic encryption
• Groups & Communities — Create, manage, invite, membership approval, subgroup linking
• Newsletters — Create, join, send messages, reactions
• Status — Text, image, and video status posts with privacy controls
• Contacts — Phone number lookup, profile pictures, user info, business profiles
• Presence & Chat State — Online/offline, typing indicators, blocking
• Chat Actions — Archive, pin, mute, star messages
• Profile — Set push name, status text, profile picture
• Privacy — Fetch/set privacy settings, disappearing messages
• Modular — Pluggable storage, transport, HTTP client, and async runtime; SQLite, Tokio WebSocket, and ureq ship as the defaults, swap any of them with default-features = false
• Runtime agnostic — Bring your own async runtime via the Runtime trait (Tokio included by default)

For the full API reference and guides, see the documentation.

Quick Start

[dependencies]
whatsapp-rust = "0.6"
tokio = { version = "1", features = ["macros", "rt-multi-thread", "signal"] }

use whatsapp_rust::prelude::*;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let bot = Bot::builder()
        .with_backend(SqliteStore::new("whatsapp.db").await?)
        .on_qr_code(|code, _timeout| async move {
            println!("Scan to pair:\n{code}");
        })
        .on_message(|ctx| async move {
            if ctx.message.text_content() == Some("ping") {
                let _ = ctx.reply("pong").await;
            }
        })
        .build()
        .await?;

    // Runs until logout or shutdown; a single await.
    bot.run().await;
    Ok(())
}

The default cargo features wire up the Tokio WebSocket transport, the ureq HTTP client, the SQLite store, and the Tokio runtime; only the storage backend has to be chosen explicitly. Every piece is replaceable through the builder (with_transport_factory, with_http_client, with_runtime) for custom environments such as wasm or embedded targets.

One dependency is enough

whatsapp-rust re-exports the whole stack, so you never need to declare the sibling crates (wacore, wacore-binary, waproto, whatsapp-rust-tokio-transport, whatsapp-rust-ureq-http-client, whatsapp-rust-sqlite-storage) yourself, including when pinning a git revision:

[dependencies]
whatsapp-rust = { git = "https://github.com/oxidezap/whatsapp-rust", rev = "<commit>" }

• Protobuf types: whatsapp_rust::waproto::whatsapp (aliased as wa in the prelude)
• Core protocol/types: whatsapp_rust::wacore, whatsapp_rust::wacore_binary (Jid is also at the crate root)
• Bundled implementations: whatsapp_rust::transport::TokioWebSocketTransportFactory, whatsapp_rust::http::UreqHttpClient, whatsapp_rust::store::SqliteStore, each behind its default-on cargo feature (tokio-transport, ureq-client, sqlite-storage)

With default-features = false, pick only what you need (e.g. features = ["tokio-runtime", "tokio-transport", "ureq-client"] for a custom store while keeping the bundled networking).

To run the bot in the background instead of blocking, use spawn() and keep the handle:

use whatsapp_rust::prelude::*;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let bot = Bot::builder()
        .with_backend(SqliteStore::new("whatsapp.db").await?)
        .build()
        .await?;

    let handle = bot.spawn(); // full Client API stays available via handle.client()

    tokio::signal::ctrl_c().await?;
    handle.shutdown().await; // graceful: flushes pending state, then stops
    Ok(())
}

Run the included demo bot:

cargo run --example demo                              # QR code only
cargo run --example demo -- -p 15551234567            # Pair code + QR code
cargo run --example demo -- -p 15551234567 -c MYCODE  # Custom pair code
