#1. CREATE THE TOKEN
# This function is used to create the token. This will provide us with the credentials required access our SMTP servers.
# It takes 3 arguments, who the token is created by, the name of the token and whether or not we want the token to create new contacts.
# You'll also notice an "Authorization" header. You must use oAuth in order to authenticate and generate a token via our API.

        "createdBy": created_by,

#2. SET VARIABLES
# Here we define who we want to send the email from and who we wish to send the email to. We also specify additional components of the email 
# for instance the subject line and the body.
FROM_EMAIL = "{{YOUR_EMAIL_ADDRESS}}"
TO_EMAIL = "{{RECIPIENTS_EMAIL_ADDRESS}}"
SUBJECT = "SMTP API - Test Email w. attachment"
MESSAGE = "This is a test email send using HubSpots SMTP API. You'll notice it includes an attachment"


#3. SEND EMAIL
# This function takes the SMTP token we generated and connects to the HubSpot SMTP server to trigger the send of the email.
# notice how we use the variables above to specify the subject and the body of the email itself.
