- Does Paytm charge 2% for standard UPI transactions?
- Paytm's public pricing page lists standard UPI at zero transaction charge. Cards, wallets, EMI, international instruments, convenience fees, or merchant-specific terms can have different rates. Check the live pricing page and your signed agreement.
- Is VyaparGateway a replacement for every Paytm product?
- No. Paytm provides a broad payment ecosystem. VyaparGateway is positioned as a UPI checkout orchestration layer for supported connected merchant accounts; it does not claim to replace Paytm card, EMI, wallet, acquiring, or consumer products.
- How does Paytm webhook verification differ from VyaparGateway?
- Paytm documents a product-specific checksum mechanism and maintained checksum utility. VyaparGateway uses a conventional HMAC-SHA256 signature over the timestamp and exact raw request body. Implement the exact protocol for the sender instead of reusing one verifier.
- Which option is cheaper for a merchant using only standard Paytm UPI?
- On published transaction charges alone, Paytm standard UPI at ₹0 is lower than a ₹300 monthly software plan. The decision should then compare API workflow, reconciliation, account eligibility, plan limits, support, settlement terms, and the cost of operating the integration.
- Can a browser securely call either merchant API directly?
- No. Merchant keys, API keys, and checksum secrets belong on a backend. The browser should receive only a customer-safe token, hosted checkout URL, QR, or UPI intent produced by the server.
