More than placing a payment button.

A reliable integration connects checkout, the payment provider, your server and the order system so each transaction reaches the correct final state.

01

Gateway Setup

Connect the selected provider to your website or app using the gateway’s supported SDK or checkout flow.

02

Verification & Webhooks

Validate payment results on the server and process provider webhooks for reliable transaction updates.

03

Orders, Refunds & Status

Connect payments with order records, user messages, receipts, refund flows and transaction history where required.

Designed for successful and unsuccessful transactions.

Real payment flows include cancellations, timeouts, repeated callbacks and pending transactions. We plan these states instead of treating checkout as a single happy path.

Questions before integrating payments.

Which payment gateways can you integrate?

Depending on your platform and account availability, we can integrate providers such as Razorpay, Stripe, PayPal and PayU.

Can you add UPI and card payments?

Supported payment methods depend on the chosen gateway, merchant account and region. We enable the methods available to that account.

Do you provide a payment gateway account?

No. The merchant account and approval remain with the payment provider. We handle the technical integration.

Can you fix an existing payment integration?

Yes. We can review checkout, verification, webhook or status-handling problems and propose a scoped fix.
