Add internal note
Add a note only people in your organization can see.
MCP tool kustomer_write → add_note
write Confirm
Adds an internal note to the conversation, visible only to users in your organization and never sent to the customer. A note holds at most 10,240 characters. Mention a user or team with @ and the name: each mention is notified, up to 20 per note, which is why this call asks first. A note can be edited or deleted in Kustomer afterwards. By default you confirm each call; you can switch that off for this tool.
Parameters
| Name | Type | Description |
|---|---|---|
| conversation_id string required | string | Conversation ID from search_conversations. |
| body string required | string | Note text, visible inside your organization only. |
