Hi @Golfer99 and welcome to the Community!
At what point are you stuck with EasyMorph? Sending a web request? Parsing the response? Iterating across the CSV?
Typically, you would have to create a “Web Location” connector, and then use the “Iterate web request” action to send a web request to geocod.io for every row in your CSV file.
Here is a topic with a similar case, but using SmartyStreetAPI: Verifying address data with SmartyStreets API
Here is a topic on using Iterate / Web Request: Example: use of Web Request and Iterate Web Request with the Community forum API
