Summary

Add, remove, promote, or demote participants in an existing WhatsApp group. The account must be connected and an admin of the group; the operation requires SocialMate Pro.

Inputs

  • Account Name or ID — Account to use. If left empty, the node selects the account automatically when the API key is bound to one account; otherwise, choose an account.
  • Group Name or ID (required) — Existing group ID/JID ending in @g.us. Select one from the list or provide an ID by expression.
  • Participants (required) — Comma-separated phone numbers in full international format or WhatsApp JIDs. The node converts phone numbers to participant JIDs; the UI specifies 1–256 recipients.
  • Action — Action to apply to the listed participants: Add (default), Remove, Promote to admin, or Demote.

Output shape

A single result object per input item.

The API result is returned as JSON, typically {success: true}; it includes no per-participant outcome. WhatsApp may silently refuse to add someone due to their privacy settings, so use Group: Get afterward to check the actual participant list. Adding participants immediately puts the group on their phones.
