Download pdf file from URL

Hi Community,

We need to retrieve a pdf file from URL that is stored as a link under the attachments of a material. The ultimate goal is to store this pdf as an attachment to a customer quote.

The URL is a regulare one that is publicly available w/o authentication. Meaning I can simply enter the URL (http://somehost.com/path/file.pdf) in webbrowser to get the file.

Is there any way to achieve this? We tried using the REST API but currently fail with an RABAX error whenever we call the REST service.

Any help appreciated,

Daniel
