Stefan, I could obtain the solution : the remote API has a bug : the error message sent was inappropriate, they are going to change it.
Here I am reassured ☺

True ... is there some other system in between? I mean, a request from Appian goes a different route than from your local machine using Postman.

Thank you Stefan, but in this case why I don't have the same issue in Postman ?

This looks good to me. I am not sure about the PDF format. I assume this also uses some kind of compression. If this other system now checks the binary content for a ZIP signature, this might lead to issues. But this is just guessing !?!

I've just saw the encoding field (gzip), but not any Zip document type for the requested param :

Did you check the outgoing headers in the HTTP request? Do they include any hint on the ZIP document type or file name?
