The work file service is a temporary storage system which allows you 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.

Request Parameters

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

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:

POST /PCCIS/V1/WorkFile
Content-Type: application/json
Accusoft-Affinity-Token: ejN9/kXEYOuken4Pb9ic9hqJK45XIad9LQNgCgQ+BkM=

{

Name Description

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.

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" },

    ]
}

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

}

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`.

GET /PCCIS/V1/WorkFile/{fileId}

Gets the file bytes associated with a work file resource (used to download output files).

Example:

GET /PCCIS/V1/WorkFile/Xe6zv3dH0kVSzLuaNhd32A
Accusoft-Affinity-Token: ejN9/kXEYOuken4Pb9ic9hqJK45XIad9LQNgCgQ+BkM=

`Accusoft-Affinity-Token`	If there is more than one machine in the cluster (an `affinityToken` was provided in the response to the initial POST request to create the work file), then this header must be set to the `affinityToken` of the work file you are trying to access.

Request Parameters

GET /PCCIS/V1/WorkFile/{fileId}{?ContentDispositionFilename}

Name Type Description Example

fileId string Required. The fileId of the work file whose file bytes you want to download. Xe6zv3dH0kVSzLuaNhd32A

`ContentDispositionFilename`	string	The filename which will be used in the response Content-Disposition header, but without any file extension. The file extension will be supplied for you automatically. For example, if you specified a `ContentDispositionFilename` of `FinancialReport` and the `fileExtension` for the work file was `"pdf"`, then the response would contain the following header: `Content-Disposition: attachment; filename=FinancialReport.pdf` If you do not specify a value, a filename will be used which is based upon the `fileId` of the work file, for example: `Content-Disposition: attachment; filename=file-Xe6zv3dH0kVSzLuaNhd32A.pdf`	`FinancialReport`

ContentDispositionFilename

string

The filename which will be used in the response Content-Disposition header, but without any file extension. The file extension will be supplied for you automatically.

For example, if you specified a ContentDispositionFilename of FinancialReport and the fileExtension for the work file was "pdf", then the response would contain the following header:

Content-Disposition: attachment; filename=FinancialReport.pdf

If you do not specify a value, a filename will be used which is based upon the fileId of the work file, for example:

Content-Disposition: attachment; filename=file-Xe6zv3dH0kVSzLuaNhd32A.pdf
