Next.js Goaffpro Affiliate Integration 24 hr turn around

I run a live Next.js site on Railway.app and I already have a Goaffpro account waiting to be hooked in. I want the full affiliate toolkit—link tracking, discount-code creation, and the built-in reporting dashboard—working seamlessly for my current users without losing any of their data.

Here’s what I need you to do:
• Wire Goaffpro’s APIs or JavaScript SDK into my existing Next.js codebase so that links, coupon codes, and sales events are tracked against the right user records.
• Migrate or map my existing user data so that current customers and partners are recognised inside Goaffpro the moment the integration goes live.
• Walk through end-to-end tests on staging and production: create a test affiliate, generate a link, apply a discount code at checkout, and confirm that the sale is captured in Goaffpro’s reports.
• Hand back a concise setup note (env variables, key files touched, and any webhooks or cron jobs added) so I can maintain things long-term.

Acceptance criteria
– A test purchase using a generated affiliate link shows up in the Goaffpro dashboard with the correct commission.
– A discount code created through Goaffpro applies successfully on my live checkout flow.
– Existing site users appear in the Goaffpro user list without duplicates.
– No console or server errors after deployment on Railway.

If you’ve connected Next.js apps to Goaffpro—or similar affiliate platforms—before, you’ll get this done quickly. Let’s make sure every click and coupon counts.
