For integrating a payment gateway such as Razorpay, Cashfree, PayU, CCAvenue, or Stripe into an eCommerce website, a valid SSL certificate (HTTPS) is essential for secure communication.
Which SSL certificate is required?
| SSL Certificate | Payment Gateway Integration |
| Free Let's Encrypt SSL (DV) | Suitable |
| Paid Domain Validation (DV) SSL | Suitable |
| Organization Validation (OV) SSL | Suitable |
| Extended Validation (EV) SSL | Suitable |
Recommendation: A free Let's Encrypt SSL certificate is generally sufficient for standard eCommerce payment gateway integrations. Purchasing an expensive SSL certificate is not normally necessary.
Important requirements
- Valid HTTPS certificate with TLS 1.2 or higher.
- No expired certificates or browser security warnings.
- Secure payment gateway API and webhook endpoints.
- Payment processing through the gateway's approved checkout or tokenization solution.
- PCI DSS compliance appropriate to the payment integration.

SSL Certificate for Payment Gateway Integration
A valid SSL certificate must be installed and configured to enable secure HTTPS communication between the eCommerce website and payment gateway. SSL installation, HTTPS redirection, and certificate validity must be verified before payment gateway integration and live transaction testing.
Note: SSL protects data in transit but does not, by itself, guarantee payment gateway approval or PCI DSS compliance.
