Codebold IT Solutions · Payment Gateway Integration

Finished when the failure case works too.

A payment integration isn't finished when checkout succeeds — it's finished when a webhook fails to arrive, a card gets declined mid-flow, or a refund needs to reconcile against an order record, and the system still behaves correctly. We build with signed webhook verification and idempotent order handling.

— What you get

Scroll →

A checkout that
handles the failure
cases, not just success.

01

Orders created before payment, not after

The order exists server-side first, so the payment always maps back to a real record — nothing gets charged without something concrete behind it.

  • Order-First Flow
  • Data Integrity

02

Card data never touches your servers

Sensitive payment details handled directly by the gateway, keeping your own infrastructure out of PCI scope where it doesn't need to be.

  • PCI Compliance
  • Secure Handling

03

Webhooks verified, not just trusted

Signed webhook verification confirms a payment result is genuine before any order status changes — a real defense against spoofed requests.

  • Webhook Verification
  • Signed Payloads

04

Retries never double-charge

Idempotent order handling means a retried request can't accidentally charge a customer twice, even under real network failure conditions.

  • Idempotency
  • Retry Safety

05

Declines are recoverable, not lost sales

Clear failure states let a customer retry or fix the issue, instead of a declined payment silently ending the checkout attempt.

  • Failure States
  • Checkout Recovery

06

Reconciliation handled automatically

Successful, failed, and refunded payments reconciled against order records without someone manually cross-checking a spreadsheet.

  • Reconciliation
  • Refund Handling

— How a payment moves from checkout to confirmed order

01

01

Order created

An order is created server-side first, so the payment always maps back to a real record — nothing gets charged floating free without something concrete backing it.

02

Secure payment

Card details are handled directly by the gateway, never touching your own servers — the sensitive part of the transaction happens entirely outside your infrastructure.

03

Webhook verification

A signed webhook confirms the payment result, verified before any order status changes — the signature check is what stops a spoofed request from faking a successful payment.

04

Reconciliation

Successful, failed, and refunded payments are reconciled automatically against order records, so the books stay accurate without manual cross-checking.

— Why Codebold

Declines are recoverable, not lost sales.

Building software since 2013.

✓

We treat the failure cases as the real work

A payment integration isn't finished when checkout succeeds — it's finished when a webhook fails, a card declines mid-flow, or a refund needs to reconcile, and the system still behaves correctly.

✓

Retries never double-charge a customer

Idempotent order handling means a network retry can't accidentally charge twice — a real, if invisible, protection that only shows its value when something actually goes wrong.

✓

We stay after launch

Fixes, updates, and the next feature are part of the relationship — not a renegotiation every time something needs to change.

— Tech depth

— Good questions

Before you ask, we'll answer.

Razorpay and Stripe most commonly, with the same rigor — signed webhook verification, idempotent handling — applied regardless of which provider fits your market and business.

No — card details are handled directly by the gateway, keeping your own infrastructure out of that sensitive scope entirely.

The reconciliation process is built to catch and correct for that — a missed webhook doesn't mean a payment silently falls out of sync with the order record forever.

Yes — the checkout flow, webhook handlers, and everything built are yours from day one.

We stay on. Fixes, updates, and the next feature are part of the relationship, not a separate negotiation.

Depends on the checkout flow's complexity. You'll get a clear timeline after a discovery call.
