API Model for CamelCamelCamel Service
Understand data entities, API endpoints, and message formatting for the CamelCamelCamel API service.
In this lesson, we’ll define the base URL and endpoints of the C3 service to perform different operations. We’ll examine the data entities needed to meet the functional requirements of the C3 service. We’ll analyze request and response message formats for the fundamental functional requirements.
Base URL and API endpoints
We can use the following URL as the base URL of the C3 service:
The api.c3.com represents the host URLs of the C3 service. We’ve already seen that the version is used to update different services related to the API or to fix bugs. Because this is the first C3 API that we are designing, we assume the version to be v1.0. Lastly, the service indicates the endpoint we’ll use to perform different operations. The set of operations are listed in the following illustration:
