3. Security Information

URL white listing

The following URLS should be white listed:

• https://mtdapi.cloud.taxsystems.com

Proxy

If you have a proxy enabled, the AlphaBridge Excel file is not aware of this. There are different methods that can be used to resolve this issue; however, the popular option is to add netsh winhttp set proxy proxyserver:port into the PC config using the command line.
