errRequired Parameter VendorRef is Missing In The Request
Reason:
This error happens when the numbers or IDs used to identify things aren't correct. For example, if you're sending information about a vendor (like a business or person you buy from), make sure the ID you're using is really for a vendor. The same rule applies for customers and employees each ID has to match what it's supposed to represent.
Steps to Resolve:
Create a New Vendor - In your QuickBooks Application create a new Vendor.
Re-download QuickBooks Data - In Webgility Online, go to Sync Settings> Fees, then click the refresh icon in the upper right corner. After that, select the correct Payee under Sync Settings> Fees and click Save to update your configuration.
Once the changes have been made retry posting the order.
