API fulfillments
API fulfillment refers to an API called as part of skill
fulfillment.
For example, a skill named “Order Pizza” might be a framework for a conversation where the user can ask Coleman to order a pizza, and Coleman will send a request via API to the local pizza delivery service. The API fulfillment would be the API request to the pizza place for the user-specified pizza.
Not all skills call an API as part of fulfillment.
