Supergood | American Express Global Business Travel API
Programmatically access American Express Global Business Travel’s corporate travel workflows—traveler profiles, bookings, approvals, duty of care, and spend reporting—via a stable REST API. Supergood builds and operates production-grade, unofficial Amex GBT integrations so your team can automate trip sync, approvals, invoice exports, and alerts without heavy custom engineering.
American Express Global Business Travel (Amex GBT) is software and services that help companies plan, book, and manage business travel across flights, hotels, rail, and car rental, with policy enforcement, approvals, duty of care, and analytics. With an unofficial API, you can sync traveler profiles from HR, pull upcoming and historical trips with normalized segments, submit and track approvals, export invoices and receipts to finance, and monitor disruptions or risk events—directly inside your operational systems.
If you’re a tech company integrating Amex GBT, you can push profile updates and preferences, pull real-time itineraries and trip status, create approval requests and capture outcomes, and automate spend feeds into ERP or expense tools. You can also enrich data with emissions calculations, power traveler communications (e.g., Slack/Teams notifications), and unify policy and compliance signals with your procurement stack.
What is American Express Global Business Travel?
Amex GBT is a leading corporate travel management company (TMC) and technology provider that delivers:
- Booking and Trip Management (air, hotel, rail, car)
- Policy Enforcement and Approvals

- Duty of Care, traveler tracking, and disruption support
- Invoicing, reporting, and analytics
Common data entities:
- Travelers and Profiles (identities, documents, preferences)
- Trips and Itineraries (PNRs, ticket numbers, segments)
- Bookings and Status (booked, ticketed, canceled)
- Approvals and Policy Violations
- Cost Centers, Departments, and Budgets
- Invoices, Receipts, and Line Items
- Risk Alerts and Duty of Care events
- Emissions and Sustainability metrics
The Amex GBT Integration Challenge
Organizations rely on Amex GBT daily, but turning portal-centric workflows into automated pipelines is challenging:
- Product entitlements and account configuration: Access differs across platforms (e.g., Neo/Egencia), regions, and negotiated content
- Enterprise security controls: SSO, MFA, and network restrictions complicate headless automation from service accounts
- Portal-first experiences: Advanced capabilities (approvals, policy, reporting) often live in the web app; official APIs may be limited or partner-only
- Data fragmentation and normalization: Bookings span GDS/NDC sources with varying PNR schemas, while invoices can be PDFs or scheduled CSV exports
- API availability and cost: Some customers report premium pricing or limited API exposure, leading to reliance on batch exports and manual processes
How Supergood Creates Amex GBT APIs
Supergood reverse-engineers authenticated browser flows and network interactions to deliver a resilient API endpoint layer for your Amex GBT workflows.
- Handles username/password, SSO/OAuth, and MFA (SMS, email, TOTP) securely
- Maintains session continuity with automated refresh and change detection
- Normalizes responses so you can integrate once and rely on consistent objects across capabilities (travelers, trips, approvals, invoices)
- Aligns with customer entitlements and licensing constraints to ensure compliant access across platforms and markets

Frequently Asked Questions
Q: Which Amex GBT products can this integration cover?
Supergood supports workflows across booking/trip management, approvals/policy, duty of care signals, and invoicing/reporting, subject to your licensing and entitlements. We scope coverage during integration assessment.
Q: How are MFA and SSO handled for automation?
We support username/password + MFA (SMS, email, TOTP) and can operate behind SSO/OAuth when enabled. Sessions refresh automatically with secure challenge handling and change detection.
Q: Can I receive itinerary changes and risk alerts?
Yes. You can subscribe to webhooks for schedule changes, cancellations, disruptions, and duty of care events, or poll endpoints with ETag/If-Modified-Since semantics.
Q: How do you normalize segments across GDS/NDC and suppliers?
We standardize PNRs, ticket numbers, fare classes, hotel rate codes, and supplier metadata into consistent objects so your downstream systems don’t need to handle source-specific schemas.
