Frequently Asked Questions
Common questions about this service and our deliverables.
Which payment gateways can you integrate?
We integrate Razorpay, Stripe, PayPal, PayU, Cashfree, Flutterwave, Paystack, mada, Tap Payments, and Authorize.Net depending on the target market.
Can you integrate WhatsApp Business API for automated messages?
Yes. We integrate the official WhatsApp Cloud API (Meta) to send automated order confirmations, appointment reminders, invoice receipts, and OTP verifications.
Do you integrate Google and Microsoft APIs?
Yes. We connect applications to Google Calendar, Gmail API, Google Sheets, Microsoft Graph (Outlook, Teams, OneDrive), and Google Maps Platform.
How secure are the payment integrations you build?
We integrate with established payment providers such as Razorpay and Stripe using secure hosted or tokenized payment flows, server-to-server API calls with environment variables, and no API keys in client-side code. Each client remains responsible for validating the PCI DSS scope and compliance requirements of its complete payment environment.
Can you integrate an API that has poor or missing documentation?
Usually, yes. We start with a short feasibility review of the provider's endpoints, authentication and rate limits. If the API is undocumented, we quote a discovery phase first so you know the risk before committing to the full integration.
