POST /v2/viewingSessions/{viewingSessionId}/contentConverters

Routes key: CreateContentConverterV2

Starts a conversion process for the source document of a particular viewing session. This URL has the following parameters:

Parameter Description
{viewingSessionId} The ID provided in the response from POST /ViewingSession.

Request

Body: Empty. An error will be returned if any data is present.

NOTE: PDF is currently the only supported destination format. A successful response will include several input properties as shown below. A future release will allow these properties to be set in the request body to create various kinds of output.

Response

Body: a JSON object with the following properties:

Property Type Description
input {object} An object that specifies the input used for the conversion.
input.dest {object} An object that specifies the destination file format and any additional details which control how the content is converted.
input.dest.format {string} Specifies the output file format.
input.dest.pdfOptions {object} An object that specifies additional options when input.dest.format is "pdf".
input.dest.pdfOptions.forceOneFilePerPage {boolean} If true, the conversion process will produce single-page PDF files, one file for each page of content (instead of a single PDF with multiple pages). Default is false.
input.sources {object} An array of objects, one for each input file.
input.sources[n].pages {string} The page numbers and/or page ranges, separated by commas, of the source document to convert.
processId {string} The id of the contentConverter resource which represents the file conversion operation.
state {string} The current state of the conversion process, which will be one of the following: "processing", "complete", or "error". If "processing", the conversion is still in progress. If "complete", the conversion has completed successfully. If "error", the conversion failed due to a problem. For the initial POST, this value will almost always be "processing". Results are typically only available with a subsequent GET.
percentComplete {integer} An integer from 0 to 100 that indicates what percentage of the conversion is complete.
errorCode {string} An error code string if a problem occurred during the conversion process.
