FREQUENTLY ASKED QUESTIONS
Questions About Payment & API Integration
Clear, transparent answers to help you evaluate technical feasibility, timelines, and business returns.
Q. Which payment gateway is best for businesses in Bihar?
Razorpay and PhonePe are currently the most reliable options in India, offering high UPI success rates, fast onboarding, transparent settlement cycles, and simple dashboard tools.
Q. Do we need a current business bank account to accept payments?
Yes. Indian payment gateways require an active business current account, GSTIN (or MSME registration for proprietorships), and KYC documentation.
Q. How are failed transactions or refunds handled?
Our integrations include automated webhook listeners that immediately update order status upon receipt of gateway callbacks, along with dashboard refund triggers.
Q. Can we send automated payment receipts via WhatsApp?
Yes. Upon successful transaction confirmation, our system can trigger an automated WhatsApp confirmation message with a downloadable PDF receipt.
Q. How long does payment gateway integration take?
Once your merchant account is approved by the gateway provider, technical integration and testing are typically completed in 3 to 7 business days.
