Best Payment Gateway for Startups in 2025

Here are QA scenarios to validate Paytm's compliance with these revised limits:

• Auto-Split Functionality

Transaction exceeding P2P limits
Transaction exceeding category-specific limits
Transaction split behavior
Successful auto-split

• Reversals

Failed transaction within P2P limits
Failed transaction within category-specific limits (P2M
Compensation for delayed reversals
Communication for failed transactions

• Refunds

Failed UPI transaction with debit but no credit
User-initiated refund for incorrect transaction
Refunds for amounts exceeding standard limits (P2M)
Grievance redressal for refunds

To enforce the new UPI caps, ensure your PayU integration supports these higher limits by confirming that your system correctly handles the increased per-transaction and daily amounts for eligible Person-to-Merchant (P2M) payments in categories like investments, insurance, and travel. Verify that your backend logic checks and enforces these limits, especially for verified merchants, and that you have integrated any necessary updates from PayU's developer documentation to process these higher-value transactions correctly.

If you purchase an item using PayPal's installment payment option and receive a refund, the amount of the refund will be applied directly to your loan balance, lowering the amount you owe on the remaining installments. If the refund is greater than the remaining balance, the difference will be credited back to your PayPal account.
