# Depot attachments

Registers the attachment routes on mux.

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

### GET `/api/v1/tickets/{ticketID}/attachments` {#depot.attachments.listTicket}

**listTicketAttachments returns every live attachment on the ticket, whether it rode in on a message or was added to the ticket itself.**

The conversation already carries the per-message files, but a file uploaded
from the console's Attachments section has no message, and the message list
keys by message id, so those were reachable by nothing. This is the one
place that shows the whole set. Same view type as the message list, so the
console has one shape to render and one downloadUrl to trust.

#### Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `ticketID` | path | string | Yes | A uuid. |
| `page` | query | integer | No | One-based page number. Defaults to 1. |
| `pageSize` | query | integer | No | Rows per page, 1 to 200. Defaults to 50. |

#### Responses

| Status | Body | Description |
| --- | --- | --- |
| `200` | `application/json`, PagedResultTicketAttachmentRefView | Success. |
| `401` | `application/problem+json`, ProblemDetails | No signed-in identity. |
| `403` | `application/problem+json`, ProblemDetails | The identity does not hold ticket:read. |
| `404` | `application/problem+json`, ProblemDetails | No resource matches that id. |
| `500` | `application/problem+json`, ProblemDetails | No client store in request context. |

using System;
using System.Net.Http;

using var client = new HttpClient();

var request = new HttpRequestMessage(HttpMethod.Get, "https://depot.example.com/api/v1/tickets/<ticketID>/attachments?page=0&pageSize=0");
request.Headers.TryAddWithoutValidation("X-CSRF-Token", "<csrf-token>");
request.Headers.TryAddWithoutValidation("Accept", "application/json");

Console.WriteLine(await response.Content.ReadAsStringAsync());
```

### POST `/api/v1/tickets/{ticketID}/attachments` {#depot.attachments.uploadTicket}

**uploadTicketAttachment takes one file as the raw request body.**

Raw body rather than multipart: there is exactly one file per request and no
other fields, so multipart would add a parser, a temporary spool and a set of
its own limits to carry no information. The file name travels as a query
parameter and the content type as the Content-Type header, which is where an
HTTP client already puts them.

#### Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `ticketID` | path | string | Yes | A uuid. |
| `fileName` | query | string | No |  |
| `messageId` | query | string | No |  |

#### Responses

| Status | Body | Description |
| --- | --- | --- |
| `201` | `application/json`, TicketAttachmentRefView | Created. |
| `400` | `application/problem+json`, ProblemDetails | One or more validation errors occurred. |
| `401` | `application/problem+json`, ProblemDetails | No signed-in identity. |
| `403` | `application/problem+json`, ProblemDetails | The identity does not hold ticket:write. |
| `404` | `application/problem+json`, ProblemDetails | No resource matches that id. |
| `409` | `application/problem+json`, ProblemDetails | The request conflicts with the current state. |
| `413` | `application/problem+json`, ProblemDetails | The request was refused. |
| `500` | `application/problem+json`, ProblemDetails | No client store in request context. |
| `503` | `application/problem+json`, ProblemDetails | Attachment storage is not configured on this Depot. |
| `507` | `application/problem+json`, ProblemDetails | This client's attachment storage is full. Raise the quota or remove old attachments. |

### GET `/api/v1/tickets/{ticketID}/attachments/{attachmentID}` {#depot.attachments.downloadTicket}

**downloadTicketAttachment streams one file back.**

Read the file header before changing any header this writes. The combination
of a forced generic content type, an attachment disposition and nosniff is
what keeps an email-ingested HTML file from executing on the console's origin,
and each one alone is insufficient: a browser will sniff a missing type, and
an inline HTML document runs whatever type it was labelled with.

#### Parameters

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

#### Responses

| Status | Body | Description |
| --- | --- | --- |
| `200` | `application/octet-stream`, string (binary) | Success. The body shape was not resolved; see x-outpost-unresolved. |
| `401` | `application/problem+json`, ProblemDetails | No signed-in identity. |
| `403` | `application/problem+json`, ProblemDetails | The identity does not hold ticket:read. |
| `404` | `application/problem+json`, ProblemDetails | No resource matches that id. |
| `409` | `application/problem+json`, ProblemDetails | The request conflicts with the current state. |
| `500` | `application/problem+json`, ProblemDetails | No client store in request context. |
| `502` | `application/problem+json`, ProblemDetails | The attachment could not be read from storage. |
| `503` | `application/problem+json`, ProblemDetails | Attachment storage is not configured on this Depot. |
| `507` | `application/problem+json`, ProblemDetails | The storage profile for this client is over its configured quota. Raise the quota or remove attachments. |
