Hi,
I am trying using the HTTP Request activity (package UiPath.Web.Activities is on version 1.6.0) to download a pdf file. However it gives me a pdf file that cannot be read. I also tried the given workflow with a dummy pdf from Maciej Kuzmicz:
…still the same
What am I doing wrong?
You can find the http request properties in the attached picture.temp|530x500
Hi!
please once check this out.

Hi NaNi,
I checked the workflow that is described there and it works for me. Not sure what it has to do with the authentication problem?
Best,
Fredi
Hi! I think it’s an 407 proxy authentication error. but not sure.
please once change this configuration settings.
Regards,
NaNi
Hi NaNi,
thank you! By using a proxy server for the local area network it worked. However it only worked for the dummy document that does not require an authentication.
For the document that I want to download I get the result status code 401, although I used the right credentials. I put them into the “Simple Authentication” Property of the HTTP Request activity. Is that correct?
Best,
Fredi
Edit: The result status code for the document I want to download is 200. So it seems like I am authorized. However when I try to open the pdf it cannot be loaded.
When I open the downloaded pdf file in notepad it gives me

When downloading the file manually and open it with text editor you can see the right pdf format:

Since the authentication is not a problem anymore there seems to be an issue with the encoding/bodyformat (?) of the HTTP request activity. Here you can see the properties set:
Hi @FJJJ
As a simple sanity check, does the exact same API call work in Postman (or other tool of your choice)?
Hi @loginerror and thank you for the advice. I checked with postman and got the same result. I will get back to my colleague, who gave me the link.
