This shortcode should ONLY be used when it is known that the Infusionsoft record has been updated.
For other situations you should use the update-contact HTTP POST to push updates to Memberium.
Important Note
Use this shortcode minimally because every time the page is loaded, the shortcode runs and the contact is re-synced, which requires additional API calls. That’s why we recommend using the Contact update HTTP post in the campaign instead of using this shortcode.
