Viewing Package Creators

The Viewing Package Creator API provides a facility to fully convert a document for viewing prior to the creation of a Viewing Session. If a large document is converted for viewing at the time a Viewing Session is created, the user may experience a delay when viewing later pages in the document. By converting a document prior to viewing, the entire document is available for viewing immediately.

Note that these routes do not have route keys, as they cannot be re-routed.

POST /v2/viewingPackageCreators

Headers:

Accusoft-Secret: mysecretkey

Body: a JSON object

The table below shows all the properties available for the POST Request:

Property	Type	Required	Description
input.source	{object}	Yes	Properties relevant to PAS will reside in this object. NOTE: This object will be removed before sending the rest of the body to the backend services.
input.source.documentId	{string}	Yes	A customer supplied identifier which is used to uniquely identify the resulting viewing package. The documentId is required to have a non-zero length less than 256 characters and must consist of characters defined by RFC4648 - Base 64 Encoding with URL and Filename Safe Alphabet.
input.source.type	{string}	Yes	Specify where PrizmApplicationServices can find the document. The valid values are "document", "url", or "upload".
input.source.fileName	{string}	Yes (If source.type="document")	Filename that the Storage Provider API can use.
input.source.url	{string}	Yes (If source.type="url")	URL to create a viewing session from.
input.source.headers	{object}	Optional (Used if source.type="url")	Request headers to send from PrizmApplicationServices when retrieving the URL.
input.source.acceptBadSslCertificate	{boolean=false}	Optional (Used if source.type="url")	If true, requires SSL certificates be valid. Note: to use your own certificate authority, you need to specify an agent that was created with that CA as an option.
input.source.displayName	{string}	Yes (if source.type="upload")	The display name of the document that's being uploaded. E.g. "Sample-2015-09-30T19:17:24Z.doc"
input.source.markupId	{string}	Optional	The ID to use when querying markup with the XML and JSON layer APIs. If one isn't passed, we create one from the other information we're given.
input.source.downloadName	{string}	Optional	The name that will be used when downloading the original document. We will use the "displayName" or "fileName" if this option is not provided.
input.source.fileExtension	{string}	Optional	A file extension that's used if the File Detection Service cannot determine what type of file was uploaded. We will get the extension from "displayName" or "fileName" if this option is not provided.
input.viewingPackageLifetime	{integer}	Optional	Defines the minimum number of integer seconds for the created content to remain available. By default this is 24 hours. If set to 0, content will remain available perpetually.
input.render	{object}	Optional	The object that describes rendering options.
input.render.html5	{object}	Optional	The object that describes rendering options for the HTML5 viewer. A whitelist of the following render properties is used: `alwaysUseRaster`, `rasterResolution`, `svgMaxImageSize` and `vectorTolerance`. They are described in the PrizmDoc Server Viewing Session documentation.
minSecondsAvailable	{integer}	Optional (if a value is not provided, the default value = 3600 seconds will be used)	Defines the minimum number of seconds for the conversion process to remain available to GET status. By default this is 3600 seconds because by default, the Viewing Sessions timeout after 20m.

Create a ViewingPackage 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.

PUT /v2/viewingPackageCreators/{processId}/SourceFile

Headers:

Accusoft-Secret: mysecretkey

Body: a source document of Content-Type application/octet-stream

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 http://localhost:3000/v2/viewingPackageCreators/khjyrfKLj2g6gv8fdqg710/SourceFile
   Content-Type: application/octet-stream
   Body: a document

Successful Response:

200 OK

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.

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.

580 SourceFileAlreadyProvided
Content-Type: application/json
{
    "errorCode": "SourceFileAlreadyProvided"
}

If a PUT request is made with either a missing or an invalid header Accusoft-Secret, an error similar to the one below will be returned.

403 InvalidSecret
Content-Type: application/json
{
    "errorCode": "InvalidSecret"
}

GET /v2/viewingPackageCreators/{processId}

Headers:

Accusoft-Secret: mysecretkey

Gets the status of an existing viewing package creator.

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".

Examples

GET http://localhost:3000/v2/viewingPackageCreators/khjyrfKLj2g6gv8fdqg710

Successful Response:

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

200 OK
Content-Type: application/json
{
    "input": {
        "source": {
            "type": "document",
            "fileName": "sample.doc",
            "documentId": "unT67Fxekm8lk1p0kPnyg8",

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

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

Document Error

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.

200 OK
Content-Type: application/json
{
    "input": {
        "source": {
            "type": "document",
            "fileName": "sample.doc",
            "documentId": "unT67Fxekm8lk1p0kPnyg8",

    "state": "error",
    "percentComplete": 100,
    "errorCode": "DocumentNotFound"
}

Password Errors

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.

200 OK
Content-Type: application/json

    "percentComplete": 100
}

Attachment Errors

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.
