FMTC API V3 Improvements: Faster Deal Feed Sync & Performance Upgrades

FMTC continues to improve its Deal Feed API with major performance upgrades in API V3. In this Tech Corner, we break down how faster data synchronization, optimized endpoints, and improved portal performance help deliver more reliable affiliate data at scale.

We introduced V3, new API endpoints that make downloading data from our feed even faster. While FMTC supports both the new V3 and the legacy endpoints, V3 demonstrates a marked improvement in the time you can receive data. We also enhanced the synchronization between the two API endpoints. Initially, the process took days to ensure all the information was properly synchronized and verified. FMTC is happy to report that after further optimizations, full synchronization can now be done in under an hour.

Let’s take a closer look at these API endpoints to see how they compare.

What’s New in FMTC API V3

API V3 introduces a series of backend optimizations designed to improve both speed and scalability. These updates ensure that users can access fresher deal data with reduced latency.

Key improvements include:

• Faster data processing pipelines
• More efficient API endpoints
• Improved system stability under high load
• Enhanced infrastructure for scaling data delivery

These changes allow FMTC to deliver more consistent performance as data volume and demand continue to grow.

FMTC API Endpoints Explained

FMTC aggregates and normalizes data from 19 different sources. With copious data comes the inevitable long download times to receive all relevant information. Certain data, such as quick expiration dates, need to be received as soon as possible, so FMTC has taken steps to optimize our API endpoints properly. Below are the timelines for receiving data between the legacy and the new V3 endpoints, using the same merchants.

Data Syncing

FMTC wants to ensure that the data procured from both V3 and legacy endpoints are up to date and in sync. With the amount of data FMTC handles, as well as with the human verification of the data, it is important for V3 and legacy endpoints to share updates and make the most current information available. We have optimized synchronization to deliver the latest data in less than an hour.

Portal Page Loading

Merchants, deals, and product data can be accessed both through our API endpoints and portal. Deal data can be seen on our Browse Deals page, and merchant information can be seen on our Manage Merchants page. As with the API endpoints, these pages take time to load and display. With the upcoming release of the new portal, FMTC will introduce new server-side processing to pull and display data quickly and efficiently. Not only will the initial load be faster, but it will also ensure that progressing through the pagination will load just as quickly.
