Introduction

The viewing package creators REST API allows your application to create new viewing packages (to manage existing viewing packages, use the viewing packages REST API).

A viewing package contains fully pre-converted, browser-ready content for a document. If you know ahead of time which documents are going to be viewed and you want to make the viewing experience as fast as possible for your users, you can create viewing packages ahead of time for your documents. Later, when you need to create a viewing session for a document, simply use the same documentId you used when creating the viewing package and PAS will use the pre-converted content from the viewing package.

NOTE: Creating viewing packages requires you to configure a database. See PAS Configuration for more information.

Error Responses

Duplicate POST Prior to Process Completion:

If a POST request is made with a body containing the exact same content as a request prior to the completion of the original process, an error similar to the one below will be returned:

HTTP/1.1 580 ConversionInProgress
Content-Type: application/json

{
    "errorCode": "ConversionInProgress"
}

Duplicate POST After Process Completion:

If a POST request is made with a body containing the exact same content as a prior request after that request has completed, the following error similar to the one below will be returned:

HTTP/1.1 580 DocumentIdAlreadyInUse
Content-Type: application/json

{
    "errorCode": "DocumentIdAlreadyInUse"
}

NOTE: An existing package must be deleted before re-submitting the same content for conversion.

Using a packageType with a value of pdf without a metered license:

If you are specifying packageType with a value of pdf and the license is not a metered license:

HTTP/1.1 480 FeatureNotLicensed
Content-Type: application/json

{
    "errorCode": "FeatureNotLicensed"
}

Examples of Input Validation error responses:

HTTP/1.1 480 MissingInput
Content-Type: application/json

{
    "errorCode": "MissingInput",
    "errorDetails": {
        "in": "body",
        "at": "input"
    }
}

HTTP/1.1 480 InvalidInput
Content-Type: application/json

If you are self-hosting PAS and a POST request does not include the correct Accusoft-Secret header value, you will receive an error like the one below. See PAS Configuration for more info about configuring your PAS secretKey:

HTTP/1.1 403 InvalidSecret
Content-Type: application/json

{
    "errorCode": "InvalidSecret"
}

Create a Viewing Package with extra options

PrizmDoc Server allows for render options that modify the output of the conversion process. The valid options are documented at the top of this page, but as an example, this is what a request would look like if you only wanted raster content:

NOTE: When creating a viewing package, watermarks cannot be used and will return an error.

POST pas_base_url/v2/viewingPackageCreators

PUT /v2/viewingPackageCreators/{processId}/SourceFile

Uploads the source document to use when creating the viewing package.

Request

Request Headers

Request Body

The source document to use.

A request to this URL allows the user to upload a document to an existing viewing package creator which has not yet been provided a source document. When a viewing package creator is configured with input.source.type: 'upload', viewing package creation waits until a PUT request containing the source document is received. After the source document has been successfully uploaded, viewing package creation will resume.

Examples

PUT pas_base_url/v2/viewingPackageCreators/khjyrfKLj2g6gv8fdqg710/SourceFile
Content-Type: application/octet-stream

<<file bytes>>

NOTE: See the Base URL for PAS topic for more information.

Successful Response

HTTP/1.1 200 OK

Error Responses

When uploading a document for viewing package creation, the following errors may be encountered:

PUT When Not Allowed:

If a PUT request is made to upload a file for a viewing package creator which does not have input.source.type: 'upload', then the following error will be returned:

HTTP/1.1 580 NotSupportedForViewingPackageSourceType
Content-Type: application/json

{
    "errorCode": "NotSupportedForViewingPackageSourceType"
}

PUT When File Already Provided:

If a PUT request is made to upload a file for a viewing package creator after a file has already been uploaded for that viewing package creator, then the following error will be returned:

HTTP/1.1 580 SourceFileAlreadyProvided
Content-Type: application/json

{
    "errorCode": "SourceFileAlreadyProvided"
}

If you are self-hosting PAS and a PUT request does not include the correct Accusoft-Secret header value, you will receive an error like the one below. See PAS Configuration for more info about configuring your PAS secretKey:

HTTP/1.1 403 InvalidSecret
Content-Type: application/json

{
    "errorCode": "InvalidSecret"
}

GET /v2/viewingPackageCreators/{processId}

Gets the status of a viewing package creator process.

Requests to this URL can be sent repeatedly while the state="processing". To limit network congestion, an exponential back-off algorithm is recommended. This means that the time interval between each request is increased, which results in a good trade-off between quickly discovering short conversions that have completed and preventing a large number of requests for long conversions.

Upon successful package creation, the response will have the state="complete" with percentComplete=100. The errorCode will be null. Additionally it will include an output property which will contain the created package expiration time. If there is an error during processing, the state="error" with percentComplete=100. The exception to this is, some but not all page failures. In this case the state is set to "complete".

Viewing package creation completed successfully

A response for a package that was successfully generated would look like this:

HTTP/1.1 200 OK
Content-Type: application/json

{
    "input": {
        "source": {
            "type": "document",
            "fileName": "sample.doc",
            "documentId": "unT67Fxekm8lk1p0kPnyg8",
            . . .
        },
        "viewingPackageLifetime": 2592000
    },
    "output": {
        "packageExpirationDateTime": "2016-1-09T06:22:18.624Z"
    },

    "processId": "khjyrfKLj2g6gv8fdqg710",
    "state": "complete",
    "percentComplete": 100
}

The viewing package creation process may encounter three types of errors, which it will report on as follows:

Source document not found

This error describes the conversion result for a nonexistent document. Note that upon completion in this error case, the state is set to "error" because no content could be provided for the document. Additionally, an errorCode property will be provided indicating this is the cause of the error. No output property will be provided when the process completes in an error state:

HTTP/1.1 200 OK
Content-Type: application/json

{
    "input": {
        "source": {
            "type": "document",
            "fileName": "sample.doc",
            "documentId": "unT67Fxekm8lk1p0kPnyg8",
            . . .
        },
        "viewingPackageLifetime": 2592000
    },
    "expirationDateTime": "2015-12-09T06:22:18.624Z",
    "processId": "khjyrfKLj2g6gv8fdqg710",
    "state": "error",
    "percentComplete": 100,
    "errorCode": "DocumentNotFound"
}

Incorrect password for source document

This error describes the conversion result for a password-protected document, which is not supported in this release. A password property may be provided in the request, but it will not be used. Upon completion in this error case, the state is set to "error" because no content could be provided for the document. An errorCode property will be provided indicating an "InternalError". No output property will be provided when the process completes in an error state:

HTTP/1.1 200 OK
Content-Type: application/json

{
    "input": {
        "source": {
            "type": "document",
            "fileName": "sample.pdf",
            "documentId": "unT67Fxekm8lk1p0kPnyg8",
            . . .
        },
        "password": "opensesame",
        "viewingPackageLifetime": 2592000
    },
    "expirationDateTime": "2015-12-09T06:22:18.624Z",
    "processId": "khjyrfKLj2g6gv8fdqg710",
    "state": "error",
    "percentComplete": 100,
    "errorCode": "InternalError"
}

Individual page conversion failures

These errors will not mark the entire package as errored, but rather report in the output object in a pageFailures array:

HTTP/1.1 200 OK
Content-Type: application/json

{
    "input": {
        "source": {
            "type": "document",
            "fileName": "sample.doc",
            "documentId": "unT67Fxekm8lk1p0kPnyg8",
            . . .
        },
        "viewingPackageLifetime": 2592000
    },
    "output": {
        "packageExpirationDateTime": "2016-1-09T06:22:18.624Z",
        "pageFailures": [
            {
                "errorCode": "CouldNotRetrievePngContent",
                "pageNumber": "4"
            },
            {
                "errorCode": "CouldNotRetrieveSvgaContent",
                "pageNumber": "5"
            },
            {
                "errorCode": "CouldNotRetrieveTextContent",
                "pageNumber": "8"
            }
        ]
    },
    "expirationDateTime": "2015-12-09T06:22:18.624Z",
    "processId": "khjyrfKLj2g6gv8fdqg710",
    "state": "complete",
    "percentComplete": 100
}

Attachment failures

These errors describe the failure of the conversion to provide an artifact for an attachment in the case where a document supports attachments, such as .EML or .MSG.

If the conversion process finds attachments associated with the document, but the process is unable to provide content for one or more pages, then the state is set to "complete" and an array of attachments is returned as a property in the body:

HTTP/1.1 200 OK
Content-Type: application/json

{
    "input": {
        "source": {
            "type": "document",
            "fileName": "sample.eml",
            "documentId": "unT67Fxekm8lk1p0kPnyg8",
            . . .
        },
        "viewingPackageLifetime": 2592000
    },
    "output": {
        "packageExpirationDateTime": "2016-1-09T06:22:18.624Z",
        "attachments": [
            {
                "name": "text-file",
                "errorCode": "ArtifactCouldNotBeRetrieved"
            },
            {
                "name": "document-text.pdf"
            },
            {
                "name": "last-pages-dont-exist.pdf",
                "errorCode": "CouldNotConvertSourceDocument"
            }
        ]
    },
    "expirationDateTime": "2015-12-09T06:22:18.624Z",
    "processId": "khjyrfKLj2g6gv8fdqg710",
    "state": "complete",
    "percentComplete": 100
}
