I realize I did not leave enough info. On this page, there is a link that leads to nowhere. Specifically the line that says "You can also interact with these wallets programmatically. See Use Interledger programmaticallly."
I updated the link to reach the appropriate page.
The old link (https://interledger.org/use-interledger-programmatically.html) did not exist, rather I put in the new link which is correct: https://interledger.org/setup-wallets-programmatically.html
