API Reference

API Reference

Cross-cutting reference documentation that applies across all FMTC API feeds (Deal Feed, Product Feed, Forbidden Codes Feed, and Single-Use Codes Feed).

For feed-specific documentation, see the individual feed sections in the left navigation.

In this section

  • API Versioning — How FMTC versions its APIs, the difference between explicit version pins (e.g. /api/3.2.1/) and bare-version segments (/api/3/), and how to track changes.

  • Updating To the Latest Version — Guidance for migrating your integration when a new major or minor version ships.

If you have questions about API behavior that aren't covered here or in the feed-specific pages, contact your Account Manager or support@fmtc.co.
