Next.js

What it does

• The tracker reads ?aff= from the URL and stores the click in a first-party cookie.
• Your server links each signup to that click, with your own user ID.
• Sales come from Stripe, or from your server with any payment provider.

Set up in three steps

1. Install @affitor/sdk and wrap your app in AffitorProvider with your program ID.
2. After a user signs up, call trackLead from your server with their user ID and the affitor_click_id cookie.
3. Connect Stripe and add Affitor metadata to the Checkout Session, or send each sale from your server with trackSale.
