Hopper Sessions API is one of 5 APIs that [Hopper](https://apis.io/providers/hopper-com/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Sessions. The published artifact set on APIs.io includes an OpenAPI specification and API documentation.

Hopper uses a unique ID to correlate API calls and events produced by a user's interaction with an airline application. The duration of the user's interactions is called a "session", and the correlation ID is called a `session_id`. A session begins immediately before the airline’s first API call to Hopper, and the airline must call the Create a Session endpoint at this time. A `session_id` is returned from this call; it must be included with each subsequent API call via the `HC-Session-ID` header. No airline action is required to end the session.
