Hi I'm really hoping someone can solve this one - I'm trying to retrieve a PDF document from a REST API service - is this possible using Nintex Workflow?

I have some data stored on a web service, I can successfully use the Web Request function to collect text and numerical data via various GET/POST requests to a REST API with no issues.

I need to retrieve a PDF from this same service, using cURL or PostMan I can successfully request the PDF and store the output as a file however all I get using the Web Request is a successful response and something that looks like PDF source code (maybe?), I've attached an image of the response - is there any way to retrieve a PDF using a Web Request and store in a document library on SharePoint

Any help would be very much appreciated!!
