Egencia Receipt API
Retrieval of the receipt for a booked trip item, via GET /v1/receipts/{itemId}, paired with a Receipt SPI that pushes a notification to a customer-built web service whenever a receipt is generated. The documented push payload carries booking_id, item_id, product_type, company_id, traveler_id, organization_parent_id and a HAL-style _links.receipt href back into the Egencia API - a clear illustration of how the record stays anchored to Egencia keys.
