What files would you use with Postman Visualizer?

Hi, thank you for the video; excellent job! I've followed your steps for data visualization as well as for download. However, I still need help to see the pdf file. I've tried firefox and chrome - the scroll appears in the visualization part, but the file is never shown. Is there some "trick" I might be missing? The pdf file I am requesting is from an online API shop

Excellent video, but i have a question, what's happens if i want to download a series of documents (ej. in excel format) from an API? using the collection runner?

Hello I like this video, but I have a question, how can I get the full script that you use in the video my friend? thanks

hi great video! would it be possible to somehow modify your get file option here, to use with a mock server? So I am basically after the ability to call either a file/image via API from a 3rd party, and it pull through to enable download/live view. Within mock server you can generate a random image, but on a call this provides the URL to the image and not the image itself

what if the service I'm trying to test actually returns the contents of the pdf file, not the base64 but the raw contents... ???

Hi Dev,
I am trying to upload pdf files from postman to Share Point, and the file is getting uploaded but the real problem come when i am opening the file. It is not getting opened with below error:
'We cannot open this file, something went wrong' along with this i am getting refresh message.

Could you please help me on this, it is very urgent?

Great video. . I am sending "get" a request where receive the PDF file. I need to write some test cases to check PDF is correct or not. As a workaround, I thought that I can automatically save the response (PDF) to the specific folder, after running collection and then check it manually from the folder but as noticed it is possible only through newman. Can you please advise an alternative way in postman?
