Get thumbnail method: Is there a difference in the response generated between v1 and v2 of the API

Thanks Gregory, but I get two different responses:

Response with v2:

As noted before, I used the buffer values to convert my responses to base64. Now since the buffer values are different, I am struggling to get the right base64 string. Can you please let me know how I would get the base64 string from the buffer values which are now in hexadecimal?

Or is it possible to get base64 from the text body? If yes, how?

Many Thanks.
