Our local partners for Alternative Payment Methods may block customers using VPNs. It is generally recommended to warn customers that a payment method cannot be accessed through a VPN.

Validating limits#

The invoice creation API validates the amount value. The minimum and maximum amount values may differ based on the payment provider used for each specific invoice.
INR Peer to Peer (Gateway1) uses these:

Currency	Min value	Max value	Increment step
INR	300.00 (500.00 on Sandbox and for exceptional cases in production)	100 000.00	0.01

Contact the support team if you want to confirm the limits.
