Voen Direct — Reward Monetization Offerwall

Voen Direct (voendirect.com) lets apps and websites add an offerwall, reward their users with in-app currency and earn from trusted advertisers. Delivered by Voxira.

What was built

• Offerwall: a Next.js 16 front end that publishers embed at offerwall.voendirect.com/{app_id}/{user_id}, listing offers and surveys with filters and infinite scroll
• Fraud and VPN checks: a pre-check on start that blocks offers or clicks for risky traffic, with clear notices for the visitor
• Activity: the visitor's clicks from the last seven days with their status
• QR hand-off: an Android-only or iOS-only offer opened on another device shows a QR code instead of a dead link

Developer notes

• Direct API calls: the browser calls the Voen API itself (GET /GetOffers/{app_id}/{user_id}), with no proxy, so the backend's geo-targeting and VPN checks see the visitor's real IP
• Parallel start: offers and the fraud check (GET /fraud-check/{app_id}/{user_id}) load at the same time. offers_blocked swaps the list for a notice, clicks_blocked shows a warning and disables Start Offer, and any failure of the check counts as not blocked, so a slow check never empties the wall
• Errors as states: a 403 vpn_detected and a 500 for an inactive placement each render their own screen instead of a broken page
• Signed links stay intact: every offer URL is a signed click link, opened in a new tab and never rewritten
• Short links for QR codes: long signed URLs are shortened by the app (POST /api/shortlink to /q/{code}, a 302 to the original), accepting only the platform's own redirect URLs, with codes kept for two hours in server memory
• Embedding: one full-screen iframe or web view, light or dark by ?theme=, the visitor's choice or their OS setting, with a generated share image per host
• Deployment: offer routes are dynamic, so it runs as a Next.js server (next start) behind nginx on its own subdomain, on Node 22 or 24
