FAQPage Schema
How do I integrate TapPay payments end-to-end in a React and TypeScript application?▼

Integrating TapPay payments involves loading the frontend SDK in React and TypeScript to collect card data and get a prime, then sending that prime to your backend to call the Pay-by-Prime API for transaction completion.

What sandbox credentials do I need to test TapPay API integration?▼

To test TapPay API integration, you need sandbox APP_ID, APP_KEY, PARTNER_KEY, and MERCHANT_ID configurations to securely initialize the environment and process sample test card transactions.

How does the TapPay Pay-by-Prime flow work for secure backend payments?▼

The TapPay Pay-by-Prime flow works by sending a prime token from the frontend to your backend, which then uses PARTNER_KEY to call TapPay APIs, ensuring sensitive card data never touches your server directly.

Can I use this TapPay setup to also integrate LINE Pay?▼

Yes, this setup provides LINE Pay integration guidance and common troubleshooting strategies alongside the core TapPay SDK setup and Pay-by-Prime API workflow.

Why is my TapPay sandbox transaction failing during frontend testing?▼

TapPay sandbox transactions may fail due to incorrect APP_ID or APP_KEY initialization, improper prime token retrieval, or backend API errors, which you can resolve using the provided debugging guidance and sample test cards.
