Hi Support,

I am using direct HTTP Post method for sending a letter(SendLetter). I would like to know how the file content is to be passed. In the document, its been told FileBinaryData=string. Do you have the utility to convert the File Content to String.



It is currently not possible

It is currently not possible to use HTTP POST for our Send Web Service methods as they contain a complex structure of both strings and binary data. Other methods can be accessed using HTTP POST and GET.

Please consider using SOAP. Please use our code samples and our instructions how to use SOAP from different environments.
