I got my hands on a Clover Go Dev Kit. I've got a test application that successfully...
- Runs OAuth to get an access_token, use that access token to make an ICloverGoConnectorListener(), connect to the Go via bluetooth, create a SaleRequest and run a credit card transaction.
- I can use that access_token to do REST API calls to create an Order, add Line Items and get back an Order ID.
Honestly, I can get away with just having the Clover Go SaleRequest generated Order have the single line item, as long as I can update the description from "item" to something else.
