In 1.9 and 2.0 API Docs it’s accept the following params: { "template": "", "template_id": 0, "to": [ { "name": "", "email": "" } ], "cc": [ { "name": "", "email": "" } ], "bcc": [ { "name": "", "email": "" } ], "subject": "", "body_text": "", "body_html": "", "from_name": "", "from_email": "", "reply_to_name": "", "reply_to_email": "" }
If it’s a default PDF, maybe you could just upload it in your server and link it to the email template.
