If you are seeing “ERROR: Received status code 401 while making a POST request to wix: Array ( [message] => Can't retrieve Metasite Context from Reloose. This error can occur due to Reloose failure or when the request's identities are not authorized [details] => Array ( ) )” in the Wix integration, it is due to Wix rejecting an update to a recently shipped order.
XPS Ship recommends that you give it a few minutes and retry marking that order as complete with the steps below:
Click the History/Track tab.
Next to the shipment with the update error, select the drop-down arrow.
Select "Retry Marking Order as Shipped" from the dropdown arrow next to the shipment.
The error should disappear after a few minutes and you can continue shipping your Wix orders.
* If this does not work you will need to manually update that order in Wix.
