    # @param [String] completionWebhook This webhook event is triggered once the export is completed.
    # @param [ExportResults[]] results An array of results to be exported. The equivalent of downloading results manually.
    # @param [ExportCrawledVersion crawledVersion Download the crawled version of the submitted text. The equivalent of downloading crawled version manually.
    # @param [ExportPdfReport] pdfReport Download the PDF report. Allowed only when `properties.pdf.create` was set to true on the scan submission.
    # @param [Integer] maxRetries How many retries to send before giving up. Using high value (12) may lead to a longer time until the completionWebhook being executed. A low value (1) may lead to errors while your service is temporary having problems.
    # @param [String] developerPayload Add a custom developer payload that will then be provided on the Export-Completed webhook. https://api.copyleaks.com/documentation/v3/webhooks/export-completed
    # @param [Array] completionWebhookHeaders Adds headers to the completion webhook.
