I am a Hubspot newbie so forgive me if this question sounds naive. I am developing a C# script that will allow me to take a file of email addresses and subject it to the Workflow API. I am assuming that it validates the email against the Contact table. If so, what happens if the email address doesn't exist in Contact? Does it move onto the next record or does the process stop at the error?
Workflows function only with contact records, so if you're using the Workflows API to enroll contacts by email address (see below) the email addresses must correspond to an existing contact record. If an email address doesn't exist as a contact, you'll receive a 404 error:
