Open Layer Payment Gateway API is one of 10 APIs that [Open (open.money)](https://apis.io/providers/open-financial/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Payment Gateway, Checkout, Cards, UPI, and Net Banking. The published artifact set on APIs.io includes API documentation.

Layer is Zwitch's hosted payment gateway. A few lines of layer.js render a fully PCI-compliant checkout pop-up that accepts net banking, UPI, credit/debit cards, and wallets. Server-side APIs create payment tokens, query payment status, issue full and partial refunds (including batch refunds), and download settlement reports. Mobile SDKs are available for Android, iOS, and Flutter.
