The FMTC Deal Feed API allows publishers and developers to access thousands of up-to-date affiliate deals and coupons in one place. This FAQ explains how the API works, including incremental calls, link handling, and best practices for integration.
FMTC’s Deal Feed aggregates your monetized links into a single stream, allowing access to the freshest, most accurate deals and coupons all in one place through a single API. Below, you can find frequently asked questions regarding our Deal Feed.
What is a Deal Feed API?
A deal feed API provides structured access to affiliate deals and coupons in real time. Instead of manually collecting offers from multiple networks, you can pull standardized data—such as promotions, expiration dates, and tracking links—through a single API.
The FMTC Deal Feed API aggregates offers across networks, helping you:
- Save time on integrations
- Maintain accurate, up-to-date deals
- Scale your affiliate content more efficiently
What is a FMTC Deal Feed API?
The FMTC Deal Feed API delivers a normalized stream of affiliate deals across multiple networks. It ensures consistency in formatting while keeping data fresh and reliable.
With the API, you can:
- Retrieve current deals and coupons
- Access merchant and network data
- Automate updates to your platform
- Integrate affiliate tracking links seamlessly and automatically
How the FMTC Deal Feed API Returns Affiliate Links
The Deal Feed API returns affiliate tracking links that are ready to use or can be customized depending on your setup.
Depending on your configuration:
- Links may already include your affiliate parameters
- You may need to append your tracking IDs
What Is an Incremental Call in the Deal Feed API?
An incremental call returns only the deals that have changed since your last request.
- incremental=0 will return all active deals from all selected merchants on your account.
- incremental=1 will return any deals that have been added, modified, or deleted since the last incremental call.
Instead of pulling the entire feed repeatedly, incremental calls allow you to sync efficiently with minimal overhead. For more information, you can see this Tech Corner about each call.
What is the difference between getChanges and incremental?
getChanges will get the changes only for a particular deal, while an incremental getDeals call returns all deals added, modified, or deleted since your last call. For example, your frequent calls will use an incremental call. Use getChanges when you want information on a specific deal. Since only one ID may be used at a time for this call, it is more efficient to use an incremental parameter if you need multiple calls.
How Often Should You Call the Deal Feed API?
FMTC suggests you pull incremental data every 30 minutes and full data every couple of hours because our database is updated so frequently from the networks. A limit of 500 calls per day is strictly enforced.
Who Should Use the FMTC Deal Feed API?
The Deal Feed API is ideal for:
- Coupon and deal websites
- Cashback and loyalty platforms
- Content publishers and bloggers
- Shopping comparison tools
- Mobile apps featuring offers or discounts
If your platform relies on affiliate deals, this API helps you scale faster with less manual effort.
