Affiliate Program

Sushify Next.js includes a complete affiliate system with support for multiple affiliate platforms, allowing you to grow your SaaS through partner referrals and track commissions automatically.

Important: Payment Provider Requirements

Both Rewardful and PromoteKit require Stripe as your payment provider.

• PromoteKit: Exclusively built for Stripe. Only supports Stripe Checkout, Stripe Subscriptions, and Stripe Payment Links for payment tracking.
• Rewardful: Primarily supports Stripe and Paddle (Classic) for payment tracking. Does not track PayPal transactions.

If you're using a different payment provider (LemonSqueezy, Polar, DodoPayments, etc.), you'll need to switch to Stripe in config/index.ts to use the affiliate program features.

Supported Providers

• PromoteKit - Simple affiliate management (Recommended)
• Rewardful - Stripe-native affiliate tracking (also supports Paddle Classic)

Setup

1. Configure Affiliate Settings

Enable and configure the affiliate program in your config/index.ts:

export const config = {
  // ...
  affiliate: {
    // whether the affiliate program should be enabled
    enabled: true,
    // the provider of the affiliate program
    provider: "rewardful" as "rewardful" | "promotekit",
  },
};

2. Set Environment Variables

Add the corresponding environment variables to your .env.local based on your chosen provider:

# Affiliate
AFFILIATE_PORTAL_SUBDOMAIN=""
# ... with Rewardful
REWARDFUL_API_KEY=""
REWARDFUL_API_SECRET=""
# ... with PromoteKit
PROMOTEKIT_API_KEY=""

3. Configure Provider Settings

After setting up the config and environment variables, you need to configure provider-specific settings in packages/affiliate/src/provider.
