# Depot chat

Registers the technician's own routes: the socket, the availability toggle, and the queue.

This page is generated from the Depot route table. Every operation carries the permission it needs and the anchor an agent can link to.

### POST `/api/v1/chat/available` {#depot.chat.setAvailable}

**setAvailable is the explicit toggle.**

It is REST rather than a socket frame because it is a decision: a technician who says they are taking chats and then loses their connection has still said it, and the answer has to be a status code they can see.

#### Request body

Required, sent as `application/json`.

#### Responses

| Status | Body | Description |
| --- | --- | --- |
| `200` | `application/json`, object | Success. |
| `400` | `application/problem+json`, ProblemDetails | The request body is not valid JSON. |
| `401` | `application/problem+json`, ProblemDetails | Authentication is required. |
| `409` | `application/problem+json`, ProblemDetails | Open the chat console before marking yourself available. |
| `503` | `application/problem+json`, ProblemDetails | Live chat is not available on this server. |

### GET `/api/v1/chat/queue` {#depot.chat.queue}

**queue is the waiting list.**

With a tenant on the request it is that client's queue, which is every mode
but msp. Without one it is the msp fan-out: one request, one sort, and one
honest statement about which client databases could not be read.

#### Responses

| --- | --- | --- |
| `200` | `application/json`, ChatQueueResponse | Success. |
| `400` | `application/problem+json`, ProblemDetails | One or more validation errors occurred. |
| `403` | `application/problem+json`, ProblemDetails | Another technician is on this chat. |
| `404` | `application/problem+json`, ProblemDetails | No chat matches that id. |
| `409` | `application/problem+json`, ProblemDetails | Another technician is already on this chat. |
| `500` | `application/problem+json`, ProblemDetails | Could not list clients. |
| `503` | `application/problem+json`, ProblemDetails | Live chat is not available on this server. |

### GET `/api/v1/chat/sessions/{sessionID}/messages` {#depot.chat.transcript}

**transcript is the read this feature is most careful about.**

chat:read is the reviewer's permission, and a technician does not hold it. But
a technician may always re-read a conversation THEY personally handled: it is
their own work, they were a party to it, and refusing would mean somebody
could not check what they promised a customer an hour ago. That is the same
shape Core's messages route takes with requireAnyPermission.

Anything else - a technician reading a colleague's chat - is refused, and a
read by somebody who did not handle it is written to the audit chain even when
it is allowed, because the reviewer's read is the one nothing else records.

#### Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `sessionID` | path | string | Yes | A uuid. |
| `since` | query | string | No |  |

#### Responses

| Status | Body | Description |
| --- | --- | --- |
| `200` | `application/json`, array of ChatMessageView | Success. |
| `400` | `application/problem+json`, ProblemDetails | One or more validation errors occurred. |
| `403` | `application/problem+json`, ProblemDetails | Another technician is on this chat. |
| `404` | `application/problem+json`, ProblemDetails | No resource matches that id. |
| `409` | `application/problem+json`, ProblemDetails | Another technician is already on this chat. |
| `500` | `application/problem+json`, ProblemDetails | No client context in request. |
| `503` | `application/problem+json`, ProblemDetails | Live chat is not available on this server. |

### POST `/api/v1/chat/sessions/{sessionID}/promote` {#depot.chat.promote}

**promote raises a NEW ticket from the conversation, through the same path the missed-chat fallback uses.**

A conversation that already has a ticket is refused: two tickets for one conversation is two queues for one problem.

#### Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `sessionID` | path | string | Yes | A uuid. |

#### Responses

| Status | Body | Description |
| --- | --- | --- |
| `201` | `application/json`, object | Created. |
| `400` | `application/problem+json`, ProblemDetails | One or more validation errors occurred. |
| `403` | `application/problem+json`, ProblemDetails | Another technician is on this chat. |
| `404` | `application/problem+json`, ProblemDetails | No resource matches that id. |
| `409` | `application/problem+json`, ProblemDetails | Another technician is already on this chat. |
| `500` | `application/problem+json`, ProblemDetails | No client context in request. |
| `503` | `application/problem+json`, ProblemDetails | Live chat is not available on this server. |

### POST `/api/v1/chat/sessions/{sessionID}/rate` {#depot.chat.rate}

**rate records the thumbs on a finished conversation.**

It exists on this face so a rating given out of band - over the phone, or on a
machine that went off before the tray could send it - can still be recorded.
The store refuses a second rating and refuses one on a chat that has not
ended, so neither of those is checked again here.

#### Parameters

| --- | --- | --- | --- | --- |
| `sessionID` | path | string | Yes | A uuid. |

#### Request body

Required, sent as `application/json`.

#### Responses

| Status | Body | Description |
| --- | --- | --- |
| `200` | `application/json`, ChatSessionView | Success. |
| `400` | `application/problem+json`, ProblemDetails | The request body is not valid JSON. |
| `403` | `application/problem+json`, ProblemDetails | Another technician is on this chat. |
| `404` | `application/problem+json`, ProblemDetails | No resource matches that id. |
| `409` | `application/problem+json`, ProblemDetails | Another technician is already on this chat. |
| `500` | `application/problem+json`, ProblemDetails | No client context in request. |
| `503` | `application/problem+json`, ProblemDetails | Live chat is not available on this server. |

### GET `/api/v1/chat/stream` {#depot.chat.stream}

**stream attaches one console window.**

A technician may have several open at once - several monitors, sometimes
several machines - and each gets its own Subscription. Every frame reaches all
of them; an offer rings in exactly one and the rest are told where it went.

Every rejection happens BEFORE the upgrade, so a console that cannot connect
gets a JSON problem document it can render rather than a socket that closes
with no explanation - the same discipline liveMetrics keeps, and the reason
the window cap is asked as a question here rather than enforced by evicting
somebody's oldest console.

#### Responses

| Status | Body | Description |
| --- | --- | --- |
| `101` | None | Switching protocols. The connection continues as a websocket; see x-outpost-transport. |
| `401` | `application/problem+json`, ProblemDetails | Authentication is required. |
| `409` | `application/problem+json`, ProblemDetails | The chat console is already open in as many windows as this desk allows. Close one and try again. |
| `503` | `application/problem+json`, ProblemDetails | Live chat is not available on this server. |
