So, you made a bunch of changes in QuickBooks and you updated the QuickBooks Web Connector but your changes are not showing up in Now Commerce. What gives? Well, it’s possible that the web connector didn’t really update even though it looks like it did. If you look carefully, you might see that there is a message in the web connector that says “No data exchange required”. No data exchange…
QuickBooks Web Connector: No Data Exchange Required
The web connector message “No data exchange required….No data to exchange for the application” means that the web connector has delayed the start of the next update.
The web connector will not allow another update to begin until a period of time has passed (usually a multiple of 3x-5x the duration of the previous run).
For example, if the previous run took 5 minutes, the web connector will not allow another update again for at least another 15-25 minutes. The maximum delay is 60 minutes.
If you have Auto-Run selected, the next update will eventually begin without manual intervention.
