In their own words
Aflink
Aflink is an affiliate management platform for brands, startups, creator-economy companies, influencers, and affiliates. It provides a partner portal, automated payouts, last-click attribution, and API access through its web and API platforms. Brands can set commission rates, attribution windows, and payout rules for recurring, one-time, or tier-based commissions. Referral links use a first-party 30-day token, server-side logging, and a salted IP fallback. Listed cookie windows are 30, 60, and 90 days, with custom windows on the Custom plan. Shared real-time dashboards show clicks, orders, commissions, and pending balances, with notifications and CSV export. Listed payment integrations include Stripe Connect, Fungies, PayPal, Visa Direct card payouts, and card, ACH, and wire top-ups. Tax features include W-9/W-8BEN collection and 1099-NEC and DAC7 generation on both plans. Free access covers the first five creators; additional creators cost $3.99 a month each. The Custom plan supports 6–500+ creators, unlimited concurrent campaigns, and priority email support.
