Tagged areas include Expense, Bookings, Webhook, Notification, and SPI. The published artifact set on APIs.io includes an OpenAPI specification, an API reference, and API documentation.

Near real-time push of booking and expense data out of Egencia into a customer's expense or ERP system. Egencia describes it as an "Expense capability" that pushes a message to a connected partner web service whenever a booking is created or updated, carrying either receipt or invoice information depending on company configuration, with retries if the consumer does not acknowledge. The published contract documents a subscription registration operation and the push payload. This is the principal outbound data path for a customer's own travel spend.
