PrizmDoc v12.0 - November 15, 2016
Content Conversion Service

Content Conversion

The Content Conversion API allows you to convert files from a variety of input formats to several common output formats.

To convert a file:

  1. Upload a file you want to use as input using the WorkFile API.
  2. Start a conversion operation by using the POST URL below.
  3. Check the status of the conversion by (repeatedly) using the GET URL below.
  4. When complete, a separate output file will exist which you can download via the WorkFile API.

Available URLs

URL Purpose
POST /v2/contentConverters Create and start a content conversion
GET /v2/contentConverters/{processId} Get the status of a content conversion

Note that these URLs begin with /v2, not /PCCIS/V1.

POST /v2/contentConverters

Creates a new contentConverter resource which represents the conversion process and begins converting one or multiple input files which you have previously uploaded using the WorkFile API. A successful response will include a unique processId which identifies this contentConverter. You will use this processId in subsequent GET calls to get the status and final results of the conversion.

Request Headers

Name Value Details
Content-Type application/json required
Accusoft-Affinity-Token

Affinity token returned in post response body for work file specified by fileId parameter in request body.

Example: "rcqmuB9pAa8+4V7fhO1SXzawy/YMQU1g8lLdNDe5l7w="

Only required if PrizmDoc is running in multi-server mode.

Request Body

At a high level, your request body should be JSON containing an input object with details about the sources and dest for the conversion.

Here is a minimal example:

POST http://localhost:18681/v2/contentConverters
Content-Type application/json
{
    "input": {
        "sources": [
            { 
                "fileId": "ek5Zb123oYHSUEVx1bUrVQ"
            }
        ],
        "dest": {
            "format": "pdf"
        }
    }
}

Additional options are available. Here is the full reference:

input.sources

The input.sources object specifies an array of objects, one for each input file.

Currently multiple input files are only supported when the destination format is pdf or tiff, but a future version of the product may allow you to submit multiple input source files for other destination formats.

input.dest.header

Name Description Details
input.dest.header.lines

This is a multi-dimensional array that allows you to easily position text in a particular line and column. The first string in any inner array will always be placed on the left (left-justified), the second string placed in the center (center-justified), and the third string placed on the right (right-justified). The number of items in the outer array defines the total number of text lines. You may provide between one and three lines of text for a header.

array, optional
input.dest.header.fontFamily

Specifies the name of the font that is used for the header (e.g. "fontFamily": "Courier"). The font name provided must be present on the server to be applied.

string, optional

Parameters

Name Description Details
processId The processId for a particular contentConverter. This processId was returned in the response for the initial POST. string, required

Request Headers

Name Value Details
Accusoft-Affinity-Token

Affinity token returned in post response body for content converter specified by processId parameter.

Example: "rcqmuB9pAa8+4V7fhO1SXzawy/YMQU1g8lLdNDe5l7w="

Only used if PrizmDoc is running in multi-server mode.

Response Body

While processing, the response will return JSON with only the processing details. For example:

200 OK
Content-Type: application/json
{
    "input": {
        "sources": [
            { 
                "fileId": "ek5Zb123oYHSUEVx1bUrVQ",
                "pages": ""
            }
        ],
        "dest": {
            "format": "pdf",
            "pdfOptions": {
                "forceOneFilePerPage": false
            }

    "percentComplete": 82
}

Once the processing has completed, the response will return JSON showing the WorkFile id of the output file or files.

If the output format supports multiple pages (e.g. PDF or TIFF), then only a single output file will be created. For example:

200 OK
Content-Type: application/json
{
    "input": {
        "sources": [
            { 
                "fileId": "ek5Zb123oYHSUEVx1bUrVQ",
                "pages": ""
            }
        ],
        "dest": {
            "format": "pdf",
            "pdfOptions": {
                "forceOneFilePerPage": false
            }
        }
    },
    "expirationDateTime": "2015-12-17T20:38:39.796Z",
    "processId": "ElkNzWtrUJp4rXI5YnLUgw",
    "state": "complete",
    "percentComplete": 100,
    "output": {
        "results": [
            {
                "fileId": "KOrSwaqsguevJ97BdmUbXi",
                "sources": [{ "fileId": "ek5Zb123oYHSUEVx1bUrVQ", "pages": "1-3" }]
            }
        ]
    }
}

If the output format does not support multiple pages (e.g. JPEG), then multiple output files will be created. For example:

200 OK
Content-Type: application/json
{
    "input": {
        "sources": [
            { 
                "fileId": "ek5Zb123oYHSUEVx1bUrVQ"
            }
        ],
        "dest": {
            "format": "jpeg"
        }
    },
    "expirationDateTime": "2015-12-17T20:38:39.796Z",
    "processId": "ElkNzWtrUJp4rXI5YnLUgw",
    "state": "complete",
    "percentComplete": 100,
    "output": {
        "results": [
            {
                "fileId": "N6uDE11Ed6+JQPy0POu+8A",
                "sources": [{ "fileId": "ek5Zb123oYHSUEVx1bUrVQ", "pages": "1" }]
            },
            {
                "fileId": "+4b6QW90Fb9yjDak+ALFEg",
                "sources": [{ "fileId": "ek5Zb123oYHSUEVx1bUrVQ", "pages": "2" }]
            },
