FAQ
Do I need an approved payment gateway account before ordering?
Yes. You must have an active, verified account with your chosen payment processor (e.g., Stripe, PayPal, Authorize.Net). I handle the technical integration, but account approvals rest solely with the payment provider.
What credentials do I need to provide to get started?
I will need temporary admin access to your website/server and API keys from your payment dashboard (Publishable Key, Secret Key, or Merchant ID). I will provide clear guidance on how to share these securely.
Can you integrate regional payment processors like Paystack, Flutterwave, or Razorpay?
Yes! I integrate global platforms (Stripe, PayPal, Authorize.Net) as well as regional processors including Paystack, Flutterwave, Razorpay, Mollie, and crypto gateways like Coinbase Commerce.
Do you support recurring subscription billing and multi-currency checkouts?
Yes. I can set up standard one-time payments, automatic currency switching, or recurring subscription payments depending on your platform and payment provider's capabilities.
Will you test the payment system before it goes live?
Absolutely. I conduct complete end-to-end testing in Sandbox/Test Mode to verify webhook triggers, order generation, and email receipts before switching your gateway to Live Production Mode.
Can you diagnose and fix errors on an existing payment setup?
Yes. If your checkout is failing, triggering IPN/webhook errors, or displaying card processing glitches, send me a message for a fast diagnostic and bug fix.
Do you work with custom-coded frameworks like Laravel, React, or Next.js?
Yes. In addition to CMS platforms like WordPress and Shopify, I write custom API integrations for PHP, Laravel, Node.js, React, and Next.js applications.
What happens if an issue arises after delivery?
I offer post-delivery support to ensure your checkout process runs smoothly. If any integration-related glitches occur after completion, I will inspect and fix them promptly.
