Integrating Flutterwave payments in Next.js and Express involves initializing one-time payments via hosted pages or Inline.js, generating unique tx_ref values, and verifying transactions on the backend to ensure secure, idempotent processing across 34+ African countries.

Webhook signature verification for Flutterwave API integration validates incoming event payloads by checking cryptographic signatures on your Express backend, ensuring requests are genuinely from Flutterwave and preventing fraudulent or duplicate payment fulfillments.

Yes, you can handle both recurring subscriptions and one-time payments with Flutterwave by using its billing APIs alongside webhook-based fulfillment to securely process and confirm transactions within your Next.js and Express workflows.

Unique tx_ref generation is required for Flutterwave payment processing to create distinct transaction references for every attempt, enabling your backend to accurately verify payments and maintain idempotency to prevent duplicate charges.

The best way to enforce smallest currency unit usage in Flutterwave API requests is to convert all amounts to minor units, such as cents or kobo, before sending payload data from your Next.js frontend to your Express backend for initialization.
