Checkout profile API

Production endpoint:
https://transact.ti.com/v2/checkoutprofiles

The checkout profile API gives you the ability to pull a list of API-eligible checkout profile IDs that can be used to place API orders with the order API. You can also use the checkout profile API to pull detailed information about a specific checkout profile. This API can be used to populate lists within your application.

1. Authenticate with your assigned API key and secret.
   
2. After you have received your access token, send a request the checkout profile endpoint. Multiple requests can be made in the same session with the access token as long as the token hasn't expired. 
3. The API will respond with a status code, 200 OK, and a JSON string containing the checkout profile data.
4. Additional query parameters are available to refine your search, see spec below.
