Airport Fuel Prices

Manage and optimize airport‑fuel pricing data for your organization. These endpoints enable operators to efficiently update, remove, and bulk‑manage fuel prices, supporting streamlined fuel‑order workflows and provider management.

Business Value

  • Ensure accurate, up‑to‑date fuel pricing for all airport operations.
  • Reduce manual effort and errors by enabling bulk updates and deletions.
  • Support cost control and negotiation with providers through transparent pricing data.
  • Enhance operational planning and financial forecasting with reliable fuel‑cost data.

Use Cases

  • Update fuel prices for a specific airport to reflect new agreements or market changes.

  • Remove outdated or incorrect fuel prices for compliance and data integrity.

  • Perform bulk deletions to quickly adapt to network‑wide pricing changes.

  • Integrate with internal systems to automate fuel‑price management and reporting.


Note:

Data managed by the Airport Fuel Prices endpoints is strictly bound to the operator associated with the authentication token. All operations — creating, updating, or deleting airport fuel prices — apply only to the operator for which the provided token is valid.

Operations

Webhooks

Manage webhook subscriptions for near‑real‑time event notifications. These endpoints enable partners to create, manage, and monitor webhook subscriptions for receiving flight‑related events and updates.

Business Value

  • Receive near‑real‑time notifications for flight events and updates.
  • Automate integration workflows with external systems.
  • Monitor flight operations and passenger changes in near‑real‑time.
  • Reduce polling overhead by using event-driven architecture.

Use Cases

  • Subscribe to flight updates to sync data with external booking systems.
  • Monitor passenger‑count changes for catering and ground‑service coordination.
  • Track aircraft changes for maintenance and operational planning.
  • Receive notifications for flight cancellations and time updates.

Available Event Types:

Subscribable Event Types (can be used when creating webhook subscriptions):

  • FLIGHT_CREATE: New‑flight creation.
  • FLIGHT_CANCEL: Flight cancellation.
  • FLIGHT_TIME_UPDATE: Flight‑time changes.
  • FLIGHT_AIRCRAFT_UPDATE: Aircraft‑assignment changes.
  • FLIGHT_AIRPORT_UPDATE: Airport updates.
  • FLIGHT_POST_FLIGHT_STATUS: Post‑flight status updates.
  • FLIGHT_MOVEMENT_UPDATE: Flight‑movement updates.
  • FLIGHT_PAX_COUNT_UPDATE: Passenger‑count changes.
  • FLIGHT_PAX_LIST_UPDATE: Passenger‑list changes (for example, new passengers, updated lists, passenger‑document changes).
  • FLIGHT_PERMIT_ASSIGNMENT: Flight‑permit provider assignment.
  • FLIGHT_PERMIT_UNASSIGNMENT: Flight‑permit provider unassignment.
  • FLIGHT_SLOT_PPR_ASSIGNMENT: Flight‑slot-ppr provider assignment.
  • FLIGHT_SLOT_PPR_UNASSIGNMENT: Flight‑slot-ppr provider unassignment.

Group Event Types (not subscribable; appear in webhook deliveries when multiple events occur in a short period):

  • FLIGHT_UPDATE: Group event that combines multiple flight update events when they occur in a short period of time. Includes: FLIGHT_CREATE, FLIGHT_CANCEL, FLIGHT_TIME_UPDATE, FLIGHT_AIRCRAFT_UPDATE, FLIGHT_AIRPORT_UPDATE, FLIGHT_POST_FLIGHT_STATUS, FLIGHT_MOVEMENT_UPDATE, FLIGHT_PERMIT_UPDATE.
  • FLIGHT_PASSENGER_UPDATE: Group event that combines passenger-related events when they occur in a short period of time. Includes: FLIGHT_PAX_COUNT_UPDATE, FLIGHT_PAX_LIST_UPDATE.
  • FLIGHT_PERMIT_UPDATE: Group event that combines permit-related events when they occur in a short period of time. Includes: FLIGHT_PERMIT_ASSIGNMENT, FLIGHT_PERMIT_UNASSIGNMENT.
  • FLIGHT_SLOT_PPR_UPDATE: Group event that combines permit-related events when they occur in a short period of time. Includes: FLIGHT_SLOT_PPR_ASSIGNMENT, FLIGHT_SLOT_PPR_UNASSIGNMENT.

Note: Group event types (FLIGHT_UPDATE, FLIGHT_PASSENGER_UPDATE, FLIGHT_PERMIT_UPDATE) cannot be used when creating webhook subscriptions. They only appear in webhook delivery history when multiple individual events are triggered within a short time window and are grouped together for efficiency.


For more information on setting up and managing webhooks, see the Event Notifications (Webhook) Guide.

Important:

Webhook endpoints must respond within 1 second with a 200 status code. To avoid timeouts, we strongly recommend handling webhook processing on a different task/thread and immediately returning the response to FL3XX.
