What is the best affiliate API?

It depends on what you need. To get stores, coupons and products to promote without network approvals, use the Feedico Partner API. To bring sales from many accounts you already have into one place, use a reporting aggregator such as Strackr, wecantrack or Affluent. If almost all your revenue is on one network, its own API is enough.

Which affiliate API gives commission rates?

Feedico returns the commission rate range, your net share and the programme's traffic rules for every merchant. Network APIs show rates for programmes you have joined, each in its own format; reporting aggregators focus on the commissions you already earned.

Is there a free affiliate API?

Yes. Network APIs (CJ, Awin, Impact) are free once you are approved, and the Feedico Partner API is free: you earn a 65% share of the commissions instead of paying a fee.

Which affiliate API is best for a cashback app?

A cashback app needs commission rates, cashback-allowed stores, a per-user id on links and status updates per sale. Feedico covers all four without network accounts; Affluent and Strackr suit apps that already hold their own network accounts and need transaction data.

Best affiliate APIs in 2026: 8 options compared

“Affiliate API” covers tools that do very different jobs. Some give you stores, coupons and links to promote, some collect the sales from accounts you already have, and each network has its own API. This guide compares eight of them by what they return, who they are for, whether you need your own network accounts and what they cost.

Disclosure: Feedico is our product. Facts about other tools come from their public websites in October 2026; prices and features change, so check the vendor before you decide.

How to choose

You need things to promote (stores, codes, products, links) and do not want to apply to every network: a catalogue API such as the Feedico affiliate API.
You already earn on many networks and want one report: a reporting aggregator (Strackr, Affluent) or attribution tool (wecantrack).
You run a large coupon site with your own accounts and want hand-checked deals: FMTC.
One network brings most of your revenue: its own API is free and enough. Compare them in CJ vs Awin vs Impact API.
