FAQ
What do you need from my side to start working?
I will just need your official API documentation, the necessary credentials or API keys, and temporary access to your Node.js repository or server environment.
Can you set up automated status updates for payments?
Yes! I specialize in setting up secure payment flows using Stripe webhooks, including one-time charges, recurring subscriptions, and instant status updates.
Do you double-check the backend before handing it over?
Absolutely. I never deliver untested code. I run comprehensive endpoint checks using Postman to make sure all your data and backend automations handle payloads perfectly.
