Feature Request

Problem

The message tool currently only accepts E.164 phone numbers and group JIDs as targets for WhatsApp. WhatsApp Channels (Newsletters) use a different JID format (xxxxx@newsletter) which is rejected by the target validation with:

Error: Delivering to WhatsApp requires target <E.164|group JID> or channels.whatsapp.allowFrom[0]

Background

WhatsApp Channels (launched 2023) are one-way broadcast channels similar to Telegram Channels. They use the @newsletter JID suffix in Baileys. The underlying Baileys library already supports newsletter operations:

• newsletterMetadata()
• newsletterFollow() / newsletterUnfollow()
• newsletterReactMessage()
• sendMessage() to @newsletter JIDs (for channel admins/owners)

Proposed Solution

1. Extend the WhatsApp target validation in the message tool to accept @newsletter JIDs
2. Route sendMessage() calls with @newsletter targets through Baileys' existing socket
3. Optionally: add newsletter-specific actions (e.g. newsletterMetadata, newsletterReactMessage)

Use Case

We run a satirical news site (schwerinistgeil.de) and want to automatically post top articles to our WhatsApp Channel. Currently we have to manually copy-paste content since the message tool rejects the newsletter JID.

Environment

• OpenClaw version: 2026.2.6-3
• Baileys version: bundled with OpenClaw (WhiskeySockets/Baileys)
• WhatsApp Channel invite: https://whatsapp.com/channel/0029VbCivBO47Xe2vxN6oH16
