Hosted checkout
A gateway-hosted page can reduce frontend scope while preserving agreed brand elements.
Integrations
Connect Payments Without Multiplying Complexity
Integration is not only an API call. The useful blueprint covers the payment surface, provider path, transaction state, webhooks, finance systems, support tooling, and failure handling.
Request a gateway planChoose the interface that fits the product.
One deployment may combine more than one pattern. The final design depends on control, security scope, product experience, and delivery capacity.
Web and mobile SDKs
Place payment components inside your product while keeping sensitive data paths appropriately constrained.
Server-to-server API
Own more of the payment experience and backend orchestration, with a correspondingly larger security and test surface.
Links and QR flows
Support controlled payment journeys where a full commerce integration is not the right starting point.
The integration contract
Every payment state needs an owner.
Requests, callbacks, timeouts, duplicates, reversals, refunds, and reconciliation events should have explicit behavior across systems.

Route availability, direction and per-method amount limits are published by the platform and move over time, so treat this as the current shape of an INR deployment rather than a fixed catalogue.
