Color settings in SendLetter metod

when I sending messages using SendLetter metod, can I specify what color (black-white or FullColor) should use service for print letters?
I know, that I could change color setting in "user settings -> print color", but I need specify this programmatically, when sending letter, case I have both Fullcolor and BlackWhite letters.

Hi, You cannot specify color


You cannot specify color with the SendLetter method. As you mentioned, you can specify the color settings in the User Settings area.

With kind regards,
