I have any type of file to upload using Custom Service.

I need to upload this file to D365FO via a Custom Service call.

I am wondering how we pass the file to the custom service. What would be the data type?

I have tried with different parm data types like (System.Byte[] , System.IO.Stream, StreamIo) and passed to my method that accesses the file from Postman but the same error was found after sending the request.

my custom service class mehod is >

public str uploadAttachment(System.Byte[] _file)
{
str result;

try
{
if(_file)
{
result =/file read/;
}
else
{
result =/file not read/;
}
}
catch
{
return result;
}

return result;
}

sent request and the postman error is >

Need help ..... how I can achieve this?

How to upload file with custom services

Moved from Dynamics AX forum.

Is your requirement using the JSON-based endpoint? Would using a Base64-encoded string be an option for you?

By the way, it sounds like a continuation of the discussion in Post and update person image with custom services in x++.
