Send a reply in a Conversations thread with Send Reply.

Postscript API: https://cotlet.dev/docs/api/postscript.md

`POST https://cotlet.dev/api/v1/postscript/conversations/{conversation_id}/replies`

Access: write. Confirm: waits for the user's OK before it runs.

Sends one text message in the thread to the subscriber. It counts as usage, as a campaign would, and works for US and Canadian subscribers. It does not Resolve the thread or Opt Out the subscriber; both stay in the dashboard. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `conversation_id` | string | yes | Thread from list_conversations. |
| `body` | string | yes | Message text. |
