* What you have to do
- Retrive information from a web service
- Process this information somehow
- Send a response to the webservice

* How does this happen
- HTTP is a client-server protocol
- To recieve data, a client will GET, and send with POST
- These are HTTP _verbs_

.play -edit 13-capstone/get.go

* Key Go concepts required

- Slices (of bytes) and string manipulation
- Interfaces ([[https://golang.org/pkg/io/#Reader][Reader]], [[https://golang.org/pkg/io/#Writer][Writer]], [[https://golang.org/pkg/io/#Copy][Copy]])
- Errors
- Must be run in the real world

  go run file.go
