1. What is a .qwc File?

A .qwc file is an XML file that contains the configuration data for QuickBooks Web Connector (QBWC) to communicate with third-party applications. These files hold information such as:

• The path to the third-party web service

• The app’s credentials for authentication

• Job scheduling details for data exchange

When a third-party application needs to access QuickBooks data, it uses a .qwc file to define how and when the exchange should happen through QBWC.
