Questions

I just completed an e-commerce project using the Paynova API and would like to share some technical points for everyone's reference:

1. Advantages

Clear API, easy to separate steps: initiate → authorize → capture → refund.

Webhook responds quickly; it is convenient to synchronize transactions.

Supports a variety of payment methods.

2. Notes when integrating

Need to hash in the correct order to avoid the 401 Signature Invalid error.

Use a queue to process webhooks when the system is highly loaded.

Avoid double-capture by clearly managing transaction state.

3. Discussion questions

What model is everyone using for webhook processing (queue, event bus…)?

Has anyone implemented Paynova recurring that's not my neighbor payments and developed best practices?

Looking forward to learning more from the community!
