Program at a glance

These are the pillars of how we work with affiliates today.

10% commission on net sales

Earn on completed orders after discounts. Taxes and fees may be excluded depending on region; exact terms are in your partner agreement.

30-day cookie window

Attribution lasts 30 days from your referral link click, so you get credit for shoppers who return within that window.

First-touch attribution

The first qualifying referral receives commission when the sale completes—no confusing last-click overrides.

API for plans, pricing & data

Use our affiliate catalogue API to pull destinations, plans, and live retail pricing for your site, apps, or internal tools.

Affiliate API

Two read-only JSON endpoints for your site, app or comparison table. Every plan and link comes back ready to publish, with your referral tag attached.

Authentication

Your API key goes in the URL path. Keys are issued per partner and sent in your onboarding email - keep them server-side and don't ship them in client-side code.
