Hello,
I’m trying to convert a Base64 encoded filestream encapsulated in a JSON and sent it with an HTTP request as Binary stream to an endpoint. The endpoint needs to receive a binary Filestream and a Content-Type header: application/pdf, together with two headers for authentication. Do I need to set the body content type to RAW/custom? If I do so I get a message “cannot set header accept in the string”. With Multipart/Formdata It processes, but then it breaks on the receiving side, because they want binary, not Multipart/formdata. Any ideas?
