Hello, i am useing phalcon's swift mail with MailJet as host, i have it all working but not exactly as i want. I want to use MailJet REST api with a custom id for email (as described here https://dev.mailjet.com/guides/?php#tagging-email-messages-v3 it takes a moment to load the page) but could not find how to pass the data, that is sent in the REST request to MailJet (which is a POST call in MailJet books) with the phalcon swift object (adding a text header was my best bet, but it didn't do the job).

any help or even a better idea are welcome, thanks Tal
