American Express Global Business Travel API
A self-serve developer portal at apitools.amexgbt.com handles registration, app creation, credential issuance, and a sandbox-to-production path; Egencia keeps its own developer center. Production access and full data may still require direct GBT engagement, and no official SDK suite exists.

Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Yes, via a managed API layer. Supergood builds REST APIs and MCP servers for authenticated enterprise web apps, so AI agents and internal tools can read and write data programmatically. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
American Express Global Business Travel has partial MCP support. Amex GBT announced an Egencia AI connector for Claude built on MCP in July 2026, rolling out to Egencia customers in Q3 2026. There is no public registry listing or self-serve developer documentation yet.
Partially. MCP support for American Express Global Business Travel exists but is incomplete, so what MCP clients like Claude, Cursor, and Codex can reach depends on what the available server covers.
