GMAIL API: how to get a response without the original message

Question

I am using google api for gmail. Everything works fine, I was able to connect, list and receive a message / stream, view all the elements of the stream, etc.

I want to get a response without the original message, is this somehow doable?

I think that each email software combines a different constructed reply message with the original message included, but there may be a way to get only the answer.

Thanks for any hint that would allow me to do such a thing.

It seems like the consensus is that this is not possible and that the message / stream needs to be parsed manually using your program.
