I have created a custom shipping module and it's working perfectly, but I cannot figure out how to send the shipping info via a REST API request to the shipping company's website. I tried to emulate the Fedex and UPS modules, but there has to be an easier way. I am new to the MVC architecture, so I'm having some trouble understanding.
Specifically what I am trying to do is have the API request trigger when the user finalizes their order placement. The request would only trigger if the shipping code chosen matched the custom shipping module's code. Any assistance would be greatly appreciated.
