When working on some more advanced workflows within HubSpot, I realized that you can only re-enroll contacts based on specific criteria. Then it dawned me that I could use a Seventh Sense webhook to re-enroll a contact based on any criteria or property I desired.
To provide some more context, I was trying to have contacts re-enroll based on when a custom property had been met. Learning that this was not possible, I banged my head against the wall for some time trying to figure out how I accomplish this. The answer was quite simple and was in front of me the whole time.
