American Express Global Business Travel API
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

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

Travelers
/travelersCreate or upsert a traveler profile with documents, loyalty, preferences, and approver chain.
Trips
/tripsRetrieve normalized trips and itineraries with segments across air, hotel, rail, and car.
Trips
/trips/{tripId}Retrieve detailed itinerary, including policy violations and disruption flags.
Approvals
/approvalsSubmit a trip request for approval, optionally including policy context and budget references.
Invoices
/invoicesExport normalized invoice and receipt data for finance and reconciliation.

Frequently asked questions
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.
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.
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.
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.
