Open Layer Payment Gateway API
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.
Open Layer Payment Gateway API is one of 10 APIs that Open (open.money) publishes on the APIs.io network.
Tagged areas include Payment Gateway, Checkout, Cards, UPI, and Net Banking. The published artifact set on APIs.io includes API documentation and SDKs.
