I am trying to add a web reference to a VB.net project. When I try to add a reference using the Development URL from listed in the following document "HostedCheckout eCom Integration Guide 03242017.pdf", I am getting the following error.
There was an error downloading 'https://hc.mercurycert.net/hcws/hcservice.asmx/_vti_bin/ListData.svc/$metadata'.
The request was aborted: Could not create SSL/TLS secure channel.
Is there an updated document with a new URL?
