Trying to use curl with insert_from_url to communicate with German payment service SOFORT.
Authentication works, but I am not successful in getting the xml data accepted by the server.
When I have no CRLF in my XML like
service complains: No Product, which would be multipay. Inserting an CRLF after <?xml ...?> creates an error which complains about exactly about this CRLF.
I already tried some of the features documented by Russel like FM-text-encode, --crlf and so on, but nothing works. Who knows what to do?
