When I try to send a email through: https://api.mailjet.com/v3.1/send I get back a messageID, but when I get a webhook callback on a send or open event the messageID is not matching. It seems to be being rounded to the 100's place. This is a problem because I can't use messageID that is supposed to be unique is not consistent.

I would even settle for updating the Get email message of MessageUUID. Since that is consistent between the send api and the webhook call.
