Accessing the Canada Post Sell Online API using curl

I've been trying to access the Canada Post Sell Online API (if it's even still called that, in 2014) and I'm having lots of trouble. I'm using an Ubercart module (uc_canadapost) and it doesn't seem to work or something. It looks like you used to get a Merchant ID when you used Sell Online, and with Canada Post's new APIs you get a username and password as your API key.

It took me a good 2 hours to figure out how to successfully use curl to access the REST API. I'm now going to document the examples of successful curl commands that have actually worked.
