JID Formats
WhatsApp uses JIDs (Jabber IDs) internally:
| Type | Format | Example |
|---|---|---|
| Individual | <number>@s.whatsapp.net |
34612345678@s.whatsapp.net |
| Group | <id>@g.us |
123456789012345678@g.us |
When using to= with phone numbers, OpenClaw auto-converts to JID format.
Tips
Voice Notes
Always use OGG/Opus format:
ffmpeg -i input.wav -c:a libopus -b:a 64k output.ogg
Stickers
Convert images to WebP stickers:
ffmpeg -i input.png -vf "scale=512:512:force_original_aspect_ratio=decrease,pad=512:512:(ow-iw)/2:(oh-ih)/2:color=0x00000000" output.webp
Acknowledgment Messages (ackMessage)
Send an instant text message when an inbound message is received — fires at gateway level before model inference:
{
"channels": {
"whatsapp": {
"ackMessage": {
"text": "⚡",
"direct": true,
"group": "never"
}
}
}
}
| Field | Type | Default | Description |
|---|---|---|---|
text |
string | "" |
Message to send (empty = disabled) |
direct |
boolean | true |
Send in direct chats |
group |
"always" / "mentions" / "never" |
"never" |
Group behavior |
This is different from ackReaction (which sends an emoji reaction). ackMessage sends a standalone message bubble — visible in WhatsApp Web even when reaction flips aren't.
Rate Limits
WhatsApp has anti-spam measures. Avoid:
- Bulk messaging to many contacts
- Rapid-fire messages
- Messages to contacts who haven't messaged you first
Message IDs
To react/edit/unsend, you need the message ID. Incoming messages include this in the event payload. For your own sent messages, the send response includes the ID.

3.5.0
- Added:
ackMessage— gateway-level instant message acknowledgment. Sends a configurable text message (e.g. ⚡) the moment an inbound message arrives, before any model inference. Fires at the same speed asackReaction(emoji flip). Useful as a visual cue to distinguish your messages from bot replies in WhatsApp Web where reaction flips aren't visible.
3.4.0
- Fixed: Chat search now resolves LID/JID aliases — searching by chat name finds messages across both
@lidand@s.whatsapp.netJID formats - Added:
resolveChatJids()cross-references chats, contacts, and messages tables to discover all JID aliases for a given chat filter - Improved: Search falls back to original LIKE behaviour if no JIDs resolve, so no regressions
