StickerPack — AunuBaileys exclusive (v1.0.2+)

Send a complete sticker pack — a cover plus up to 60 stickers — in a single call, using the stickerPack content form:

await sock.sendMessage(jid, {
  stickerPack: {
    name: 'AunuCore Pack',
    publisher: 'AunuCore',
    cover: { url: 'https://example.com/cover.webp' },
    stickers: [
      { data: { url: 'https://example.com/s1.webp' }, emojis: ['🖤', '🔥'] },
      { data: { url: 'https://example.com/s2.webp' }, emojis: ['😂'] }
    ]
  }
})

A flat form is also accepted: { stickers: [...], cover, name, publisher, description } directly at the top level of the content.

Photo / video albums (v1.0.2+)

await sock.sendMessage(jid, {
  album: [
    { image: { url: 'https://example.com/1.jpg' }, caption: 'First' },
    { image: { url: 'https://example.com/2.jpg' } },
    { video: { url: 'https://example.com/3.mp4' } }
  ]
})

AI label (v1.0.2+)

Mark bot replies with the AI label — private chats only:

await sock.sendMessage(jid, { text: 'An AI-generated answer', ai: true })

Polls / quizzes

await sock.sendMessage(jid, {
  poll: {
    name: 'Next feature?',
    values: ['Music', 'Games', 'Tools'],
    selectableCount: 1
  }
})

Since v1.0.3 the codebase also carries quiz poll types for newsletters, poll result snapshots, and poll updates.

Newsletters / channels

Media sent to channels uses the dedicated newsletter upload paths (fixed in v1.0.2 — previously the root cause of failed channel media). Normalize a channel JID with the helper:

const handler = sock.aunuHandler // attached to every socket (v1.0.3+)
const channelJid = handler.newsletterId(jid)
