I've been trying to connect my Square to my Quickbooks Online and keep getting the following error no matter what I do and everything is current. Even when I hit "Give permission" and go through all the steps, still, same error. Please help!
At this time the best I can suggest is following our guide to connecting QuickBooks to Square. If there is no success, you can reach out to Quickbooks support (listed at the bottom of the guide) as we cannot offer additional support here.
