Payment integration service

Razorpay integration with server-side verification and a clear payment-state workflow.

A payment button is only the visible part of an integration. Reliable implementation also needs server-side order creation, amount validation, signature verification, success and failure handling, duplicate protection, webhook planning and reconciliation. Kailvex integrates the supported Razorpay workflow into an existing website or application after reviewing the platform, account status and business process.

What the solution may include

Capabilities selected around the actual operating workflow.

Every feature remains subject to written scope, platform capability, data readiness and third-party approval.

Account readiness review

Confirm the merchant has access to the required Razorpay account, credentials and enabled products.

Secure order creation

Create payment orders from the server so amount and order references are not trusted from the browser alone.

Checkout integration

Launch the approved checkout experience with customer and order details required by the project.

Verification workflow

Verify the returned signature and update the internal order only after the expected checks pass.

Webhook planning

Use supported webhooks for delayed or asynchronous payment events when the application requires them.

Reconciliation support

Store provider references and status history needed for operational review.

Practical outcomes

Reduce operational friction without making unsupported promises.

The goal is a maintainable system that makes responsibilities, statuses and customer expectations easier to understand.

01

Safer confirmation

The application does not treat a browser success message as sufficient proof of payment.

02

Traceable references

Internal orders can retain the gateway order and payment identifiers.

03

Clear failure states

Customers and staff receive understandable next steps after cancelled or failed payments.

04

Testable deployment

Test-mode scenarios are documented before live credentials are used.

Delivery approach

Decisions are documented before the system is treated as complete.

Discovery, prototyping, implementation and acceptance are connected to the same approved business rules.

01

Technical review

Inspect the platform, existing order model, currency and payment confirmation requirements.

02

Account and key setup

Use merchant-controlled credentials and separate test from live configuration.

03

Implementation

Build order creation, checkout, verification and approved webhook handling.

04

Go-live checks

Test success, failure, duplicate attempts, amount mismatch and server logging before live release.

Scope and responsibility

Important boundaries to confirm before implementation.

Kailvex documents technical responsibilities, but the customer remains responsible for business policies, lawful operations and information supplied for the project.

  • Razorpay controls account approval, KYC, supported businesses, settlement, pricing and service availability.
  • Kailvex cannot guarantee gateway approval or prevent provider-side downtime.
  • API keys must remain under the merchant’s control and should not be sent through insecure channels.
  • Refunds, disputes and tax treatment follow the merchant’s policy and Razorpay’s supported processes.
Frequently asked

Questions to resolve before approval.

No. Account approval and KYC decisions are made by Razorpay based on its policies and the merchant’s documents.

No. The server should verify the expected signature and order details before confirming the internal transaction.

Yes. Supported webhook events can be used when the system needs asynchronous confirmation or reconciliation.

Yes, subject to the current platform architecture, available extensions and the exact checkout workflow.
