Summary points from previous discussions:
- no 'update date' fields nor webhooks in the InfusionSoft API
- The only way to trigger push notification is by setting up our triggers manually via the campaign builder or use a service like Zapier.
- IS Zapier events are limited to "New Contact"
- Use IS "Campaign Builder" to set up a campaign, triggered on the addition of a tag. Cerb workers or plugin would need to update tag each time.
- sync that happens via periodic cron jobs are least desirable (no update date makes this a full brute force sync each time and impossible to detect/resolve conflicts)
- check the API developer forums under the resources tab at http://developer.infusionsoft.com/ as there might be a "ninja" solution documented there.
