Shopify vets apps used on their site to ensure they meet certain usability standards. This does not ensure that other Shopify apps or third-party pps will function correctly with Lulu Direct. Prior to using any third-party apps alongside the Lulu Direct app, we strongly suggest placing a test order first to ensure the third-party app is compatible with Lulu Direct. 

If you are experiencing errors or unexpected behavior from Lulu Direct, we suggest consulting Shopify with information about all apps you use and testing Lulu Direct with all third-party apps turned off.
