Connection
Locked to the current worker origin.
Message
Buttons and CTA links always send as native WhatsApp interactive messages through baileys_helpers.
Only used for global /api/send. Leave empty to use the first connected instance.
Comma-separated. Max 3 buttons, 20 characters each.
Reaction
React to an existing WhatsApp message using its message ID. Use an empty emoji to remove a reaction.
Copy from instance logs or webhook payload key.id.
Message status
Poll delivery/read status for an outbound message using the id from a send response (message_id or result.key.id).
Status updates while the instance stays connected.
