A pdf is not a text file try saving as bianry.
You have not supplied any other info except an image, so no idea what your code does also.

Send where?
Again little to no info
please supply an example flow.
if you are trying to download from http endpoint you need to send correct headers
maybe this is what you are trying to do, at a guess
```auto

Sure @E1cid ...
My requirement is to POST an API with Multi-part FormData with a body content with a PDF file.
This is my flow as of now, which I am working on.
This is the parameters used in the function before calling the HTTP POST -\>

This should work untested.
```auto

There are plenty of examples if you search the forum also.
