Is SSL required for ProductCart Synchronizer?
Yes. You will be transferring confidential information (order data) from your store to QuickBooks, so a secure connection is required. There is an exception to this: SSL is not required if you are testing your installation on “localhost”. That is: you can run Web Connector against a local, testing store without using SSL (i.e. both QuickBooks and the ProductCart-powered store are running on the same desktop in this testing scenario). Otherwise, SSL is always needed.
