Egencia Company CDF API is one of 17 APIs that [American Express Global Business Travel](https://apis.io/providers/amex-gbt/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Custom Data Fields, Company, Cost Allocation, and Reporting. The published artifact set on APIs.io includes an OpenAPI specification, an API reference, and API documentation.

Manages custom data fields - the client-defined fields Egencia describes as capturing "invoicing, reporting, approval, billing" detail, commonly department, billing unit, reason for travel or project code. Documented operations cover GET /v1/companies/{companyId}/cdfs, list, create, replace and delete of CDF values under a definition, and PATCH of the value link. Custom data fields are a significant proprietary lock-in surface - a customer's own cost-allocation taxonomy is modelled inside Egencia's schema and keyed by Egencia definition and value IDs.
