# Close a conversation

POST https://api-chat.parstechai.com/v1/conversations/{conversation_id}/close

Ends the conversation. The next conversation with the same customer starts with no prior context.

Nothing is deleted: the transcript remains and stays readable. Closing only stops the earlier history being replayed to the AI. A `chat` webhook event follows with `status: closed` and `context_reset: true`.

Reference: https://docs-parschat.parstechai.com/api-reference/conversations/close-conversation

## Authentication

- `Authorization` header (bearer token, required) — Your API key, issued by ParsChat sales. One key per account, spanning every robot you own. Send it as `Authorization: Bearer pk_live_…`.

## Request

### Path parameters

- `conversation_id` (string, required) — The conversation's id, as it arrives on every webhook event.

## Response

### 200

The conversation is closed.

- `id` (string, optional) — ParsChat identifier for the conversation.
- `robot_id` (string, optional) — The robot that owns it.
- `channel_id` (string, optional) — The channel it arrived on.
- `status` (enum, optional) — Current state. The same vocabulary as the `chat` webhook event.
  - Allowed values: `answered`, `operator_attention`, `not_answered`, `closed`, `pending`
- `client` (ConversationClient, optional) — The end customer.
- `last_message_at` (datetime, optional) — When the most recent message arrived.
- `unread_count` (integer, optional) — Customer messages since the last reply from an operator, the AI or an agent: what is still waiting for an answer. System notices do not count as replies.
- `created_at` (datetime, optional) — When the conversation started.

## Errors

### 400 Bad Request Error

The request itself is malformed: a parameter is missing, unparseable, or out of range. Unlike 422, the request never reached validation of its contents.

- `error` (ErrorError, optional)

### 401 Unauthorized Error

The key is missing, wrong, revoked, or past its expiry date. All four answer `invalid_key`: telling an expired key from an unknown one would confirm to whoever holds a leaked key that it was once real.

- `error` (ErrorError, optional)

### 403 Forbidden Error

The call is understood but not permitted: a missing role, a lapsed plan, or exhausted capacity.

- `error` (ErrorError, optional)

### 404 Not Found Error

No such resource, or it belongs to another partner. We return 404 rather than 403 here, because a 403 would confirm the id exists.

- `error` (ErrorError, optional)

### 429 Too Many Requests Error

You are calling the API too fast. `details` names the limit you are held to. This never means an automated reply to an end customer was discarded: those are queued, not dropped.

- `error` (ErrorError, optional)

### 500 Internal Server Error

Something failed on our side. Retry with backoff, and quote `request_id` if it persists.

- `error` (ErrorError, optional)

### 503 Service Unavailable Error

A service we depend on (a channel provider, or our AI service) is unavailable. Retry with backoff.

- `error` (ErrorError, optional)

## Types

### ConversationClient

The end customer.

- `id` (string, optional) — Their id on the channel.
- `username` (string, optional) — Their handle, when the channel exposes one.

### ErrorError

- `code` (string, optional) — Stable machine-readable code. Branch on this, not on the message.
- `message` (string, optional) — Human-readable explanation. Wording may change.
- `request_id` (string, optional) — Log this. It is what lets support find your exact request.
- `details` (map from string to any, optional) — Machine-readable context for the code. On `capacity_exhausted` it carries `occupied`, `requested` and `capacity`; on `rate_limited`, `limit_per_minute` and `window_seconds`.
