Hey all,

Essentially I am trying to retrieve a PDF document from a API POST Call. It returns a JSON that looks like:

{
    "transactionId": "xxxxxxx-6d19-4ecf-xxxx-bada9167868e",
    "output": {
        "localization": {
            "localeCode": "US",
            "languageCode": "en"
        },
        "documentType": "SIGNATURE_PROOF_OF_DELIVERY",
        "documentFormat": "PDF",
        "documents": [

    }
}

Any way of receiving and downloading the actual PDF document?
