Frequently Asked Questions (Technical & Operations)

Understanding how payments work can be complex. We make it simple. Here are the answers to the most common questions our clients in Kolkata and abroad ask us.

Yes, absolutely. Security is non-negotiable. Payment gateways will not function on a website without an active SSL certificate.

  • What we do: As part of our web design and digital marketing packages, MedMatrix ensures your site is fully encrypted (HTTPS) before we even begin the gateway integration. This protects your customer’s card data and boosts your SEO rankings.

When a customer clicks “Pay,” data travels through several secure checkpoints before the money reaches your account.

The Flow:

  1. Customer enters details on your site.
  2. Gateway encrypts and sends data to the acquiring bank.
  3. Bank approves/declines the transaction based on funds.
  4. Confirmation is sent back to your website instantly.
  5. Settlement: The money is transferred to your bank account (usually within T+2 days).
  • Technical Integration: We can technically integrate the API within 24 to 48 hours for most platforms (WordPress, Shopify, Custom PHP).
  • Account Activation: This depends on the Payment Gateway provider (e.g., Razorpay or Stripe) approving your KYC documents. This usually takes 3 to 5 business days. We assist you in speeding this up by ensuring your paperwork is perfect.

To activate domestic gateways (like Razorpay, PhonePe, or CCAvenue), you generally need:

  • GST Certificate (for businesses).
  • Business PAN Card.
  • Business Bank Account Cancelled Cheque.
  • Website Terms & Conditions and Refund Policy (We help you draft these compliant pages).

No.

  • MedMatrix Charges: We charge a one-time professional fee for the technical integration and setup service.
  • Gateway Charges: The payment gateway provider (e.g., Stripe or Razorpay) charges a small transaction fee (usually 2% – 3%) per successful sale. We do not take a cut of your revenue.

We configure “Webhook” responses to handle failures gracefully. If a payment fails (due to low funds or bad internet), the customer is immediately shown a friendly error message and prompted to try again or choose a different payment method, ensuring you don’t lose the lead.
