Mentioning Contacts

Getting mentioned Contacts

You can get all Contacts that have been mentioned in a message by using getMentions(). This will conveniently return a list of Contacts (opens new window).

client.on('message', async (msg) => {
    const mentions = await msg.getMentions();
    
    for(let contact of mentions) {
        console.log(`${contact.pushname} was mentioned`);
    }
});

This is just a helper function for parsing the mentionedIds array available on messages. This just contains a list of user ids, so you can use this instead if you don't intend to do anything like getting their name or accessing any properties on their Contact.

Sending messages with mentions

You can mention other contacts by using the mentions option when sending a message. Note that the message text needs to also reference mentioned contacts by using the format @[number].

// Mention contacts that send you a message

client.on('message', async (msg) => {
    const chat = await msg.getChat();
    const contact = await msg.getContact();
    
    await chat.sendMessage(`Hello @${contact.id.user}`, {
        mentions: [contact]
    });
});

Example: Mention all group members

The following is a simple command that mentions all contacts in a group if someone sends a !everyone message:

// Mention everyone
client.on('message', async (msg) => {
    if(msg.body === '!everyone') {
        const chat = await msg.getChat();
        
        let text = "";
        let mentions = [];

        for(let participant of chat.participants) {
            mentions.push(`${participant.id.user}@c.us`);
            text += `@${participant.id.user} `;
        }

        await chat.sendMessage(text, { mentions });
    }
});
