Vendor Return API

in Development
BGSU has an interface that extract purchase orders and vendor returns information and then updates the a few fields in Lightspeed Retail. The process has been successfully running for more than a year. The request starting failing around October 23rd. Below is the API request and current results.
Did something change with this endpoint? Are there any plans to fix this issue?
Thanks,
Scott

So apparently Lightspeed Retail removed the unofficial API functionality. How do I go about requesting this functionality to be implemented?

Although if it was an undocumented API function that wasn't officially supported, then you unfortunately were building something that wasn't guaranteed to be there for the long haul.
Hello,
Is there Vendor return API these days?
