Introduction

The work file REST API provides a temporary storage system to upload file input and download file output. Each work file has a unique fileId which can be used to pass that file as input to a process or viewing session or to download the raw bytes of the file.

Work files should not be used for archival storage. All work files are temporary and, by default, will be deleted 24 hours after creation.

URL	Description
POST /PCCIS/V1/WorkFile when body is file bytes	Creates a work file resource from file bytes (used to upload input files).
POST /PCCIS/V1/WorkFile when body is JSON	Creates a "package" work file from a set of existing work files. Used to prepare a set of dependent files for viewing or processing (e.g. CAD with XREF).

POST /PCCIS/V1/WorkFile when body is file bytes

Creates a work file resource from file bytes (used to upload input files).

Request

Request Headers

Name	Description
`Content-Type`	We recommend you use the value `application/octet-stream` to explicitly indicate that you are uploading file bytes. If you do not provide a value, `application/octet-stream` is assumed by default.
`Accusoft-Affinity-Token`	Used to ensure that this work file will be assigned to the same machine in the cluster as another existing resource (work file, process, or viewing session). If provided, the value must be the `affinityToken` of another existing resource. If not provided, an `affinityToken` will be randomly assigned to each work file created whenever there is more than one server in the cluster.

Request Parameters

POST prizmdoc_server_base_url/PCCIS/V1/WorkFile{?FileExtension,MinSecondsAvailable}

Name	Type	Description	Example
`FileExtension`	string	File extension of the file being uploaded without any leading period. Only required when the file type cannot be automatically detected (e.g. `csv`, `tsv`, `txt`, `eml`). The `FileExtension` parameter may only accept alpha-numeric characters. Note that, if we are able to detect the file type automatically, the detected type will always be used and this value will be ignored.	`pdf`
`MinSecondsAvailable`	integer	The minimum number of seconds this work file must remain available. The actual lifetime may be longer.	`300`

Request Body

The bytes of the file being uploaded.

Successful Response

JSON with metadata about the newly created work file.

    "fileExtension": "pdf",
    "affinityToken": "ejN9/kXEYOuken4Pb9ic9hqJK45XIad9LQNgCgQ+BkM="
}

Name	Type	Description
`fileId`	string	The unique id of the new work file resource, often used later as input to a viewing session or process.
`fileExtension`	string	The file extension assigned to this resource which indicates what type of file we understand it to be.
`affinityToken`	string	A value used to identify which machine in the cluster this work file resides on. Only present when there is more than one machine in the cluster. A work file is only accessible to another resource if that resource resides on the same machine in the cluster. You can ensure that other resources you create (work files, viewing sessions, and processes) are assigned to the same machine by passing this value in an `Accusoft-Affinity-Token` request header when submitting the POST to create the other resource.

400

There was a problem with an input parameter:

FileExtension was required and not provided.

FileExtension was an invalid value.

MinSecondsAvailable was not a number.

405 - An HTTP method other than POST was used.

580 "UnrecognizedFileFormat" The file type of the uploaded bytes could not be automatically detected. You will need to manually specify a FileExtension.

POST /PCCIS/V1/WorkFile when body is JSON

Creates a "package" work file from a set of existing work files, defining one file in the set as the primary file for viewing and content conversion.

This special type of work file is particularly useful for CAD drawings which are made up of multiple files (such as dwg files which use other files via XREF).

Example

Request

Request Headers

Name Description

Content-Type You must use the value application/json to indicate that you are assembling a new work file from a set of existing work files rather than simply uploading file bytes. If you forget to specify a Content-Type of application/json, we will assume you are attempting to upload file bytes.

Accusoft-Affinity-Token Whenever there is more than one machine in the cluster, you will need to ensure that all of the work files in the set reside on to the same machine. To do this, upload the first file in the set, get the affinityToken in the response, and then use that value in an Accusoft-Affinity-Token request header for every subsequent work file POST, including this final POST to assemble a work file for the entire set.

POST prizmdoc_server_base_url/PCCIS/V1/WorkFile{?MinSecondsAvailable}

Name	Type	Description	Example
`MinSecondsAvailable`	integer	The minimum number of seconds this work file must remain available. The actual lifetime may be longer.	300

Request Body

A JSON object which specifies:

which work files are in the set
what their local paths would be
which path should be considered the primary entry point for viewing or conversion

For example:

{
    "primaryPath": "master.dwg",
    "items": [
        { "fileId": "CVBuD7DbQYNoJDqByGierQ", "path": "master.dwg" },
        { "fileId": "5qTYa3gzN9gYUb5SzqUhqg", "path": "parts/a.dwg" },
        { "fileId": "o1bLJwFGxf9QGuTkyrOqig", "path": "parts/b.dwg" }
    ]
}

Name	Type	Description
`primaryPath`	string	Required. The primary entry point for viewing or conversion. This value must match the `path` value of one of the objects in the `items` array.
`items`	array	Required. The work files which are to be included in the set and what their local paths would be.

Items

Name	Type	Description
`fileId`	string	Required. The `fileId` of a work file to be included in the set.
`path`	string	Required. A path value for this file in the set. Typically this is just the relative path of this file in relation to the primary file. Each item in the set must have a unique `path` value.

Successful Response

JSON with metadata about the new work file resource, the most important part being a new fileId which you can use to represent the entire set of files.

Response Headers

Name	Value
`Content-Type`	`application/json`

Response Body

{
    "fileId": "nkG9fiAmj27X3MhqGdbsXA",
    "primaryPath": "master.dwg",
    "items": [
        { "fileId": "CVBuD7DbQYNoJDqByGierQ", "path": "master.dwg" },

    ],
    "affinityToken": "ejN9/kXEYOuken4Pb9ic9hqJK45XIad9LQNgCgQ+BkM="
}

Name	Type	Description
`fileId`	string	The unique id of this new "package" work file, intended to be used as input to a viewing session or process which needs to consume the entire package as a single document.
`primaryPath`	string	The primary entry point which will be used for viewing or conversion.
`items`	array	The work files which are included in the set and their assigned paths.
`affinityToken`	string	A value used to identify which machine in the cluster this work file resides on. Only present when there is more than one machine in the cluster. A work file is only accessible to another resource if that resource resides on the same machine in the cluster. You can ensure that other resources you create (work files, viewing sessions, and processes) are assigned to the same machine by passing this value in an `Accusoft-Affinity-Token` request header when submitting the POST to create the other resource.

Error Responses

Status Code	JSON `errorCode`	Description
`480`	`"MissingInput"`	A required input was not provided. See the `errorDetails` in the response.
`480`	`"InvalidInput"`	One of the input values was invalid. Possible causes: `MinSecondsAvailable` was not a number. `primaryPath` did `not` match the `path` of any of the `items`. See the `errorDetails` in the response.
`480`	`"ValueMustBeUnique"`	One or more of the `path` values in the `items` array was non-unique.
`580`	`UnrecognizedFileFormat`	This will occur if you forget to specify a `Content-Type` of `application/json` when making your request. If no `Content-Type` is specified (or if any value other than `application/json` is specified), we will understand you to be making a request to upload file bytes rather than giving us JSON instructions to create a new work file from a set of existing work files. And, since we do not automatically detect JSON as a file format, this is the error which is returned. If you are trying to create a work file from a set of existing work files (as described in this section), make sure you set the request `Content-Type` header to `application/json`.
