Sync error: Incapsula security blocks the connection.

It appears that you are using the incapsula.com solution for the page safety(or your hosting provider), which blocks our requests due to security concerns.

Solution: In this instance you would need to configure it to white list Printful IPs (currently and but are not guaranteed to stay the same forever) or disable the protection for everything under /wc-api or inquire your hosting provider to do this.
