ABA PayWay

Implement and troubleshoot ABA PayWay checkout flows across frameworks, using Next.js as the primary profile in this version.

Quick Workflow

1. Confirm server configuration and runtime.
2. Build or verify purchase payload fields in the exact PayWay hash order.
3. Sign payload server-side only.
4. Open checkout from the hidden form after script readiness.
5. Verify callback parsing and logging behavior.

Framework Profiles (Next.js First)

1. Next.js (primary profile): implement signing and callback routes with App Router route handlers.
2. React SPA / Vue SPA: implement a separate backend endpoint for signing and callback handling, then call it from the client.
3. Nuxt: implement signing and callback handlers with Nuxt server routes.
4. Any framework: keep identical unsigned fields, field order, and hash algorithm.
