Payment Gateway Integration for Websites, Ecommerce Stores and Web Applications
Vylino helps businesses connect supported payment gateways with WordPress, WooCommerce, Shopify and custom web applications. The work is planned around checkout flow, payment status handling, testing, security practices and the provider’s own onboarding requirements.
Integration before transaction
A working payment button is only one part of a reliable checkout.
A complete payment flow should also handle successful payments, failed attempts, pending states, cancelled transactions, order updates and user feedback clearly. The integration should match the gateway documentation and the business process around orders or services.
Verify
Handle payment outcomes correctly
Successful, failed and pending states should update the website or order flow accurately instead of relying only on the customer’s browser redirect.
Test
Validate before going live
Test-mode transactions, callbacks, order status and customer messages should be checked before real payments are enabled.
Payment gateway integration services
What Vylino can integrate
Actual availability depends on the payment provider, merchant account, country, business category, platform and the APIs or plugins offered by the provider.
WooCommerce payment gateway integration
Configure supported WooCommerce gateways, checkout settings, order-status behavior and test transactions within the available plugin or API flow.
Shopify payment configuration
Set up supported payment options available to the merchant account and region, subject to Shopify and payment-provider availability.
WordPress payment integration
Add supported payment flows to WordPress websites for services, bookings, digital products or forms when the selected system supports secure integration.
Custom web application payments
Integrate documented APIs into supported custom applications, including server-side verification and transaction-state handling where required.
Hosted checkout integration
Use provider-hosted payment pages where appropriate to simplify checkout handling and reduce the amount of payment interface managed directly by the website.
Payment API integration
Connect documented payment APIs for order creation, checkout, status verification or callbacks when a standard plugin does not fit the required workflow.
Webhook and callback handling
Configure supported server notifications so payment status can be verified even when the customer closes the browser or a redirect fails.
Test-to-live deployment
Validate sandbox or test credentials first, then switch to live keys only after the provider account is approved and the checkout flow has been reviewed.
Checkout troubleshooting
Investigate integration errors, callback failures, order-status mismatches or checkout issues within the website and available provider documentation.
Choose the right integration method
Use the simplest reliable integration that fits the business
A standard WooCommerce or Shopify integration may be better than custom code when the provider already supports the platform well. Custom API integration becomes useful when the business has a specific workflow, application or order system that standard plugins cannot handle.
Payment-provider approval is separate from website development
Payment gateways control merchant onboarding, KYC, prohibited or restricted categories, settlements, transaction limits and account approval. Vylino can assist with the technical website integration, but cannot approve a merchant account or override a gateway’s compliance decision.
Common providers depend on the project
Depending on platform, region and merchant eligibility, a project may use providers such as Razorpay, Stripe, PayU, Cashfree, PhonePe or other supported gateways. The exact provider should be selected based on the merchant’s approved account, supported payment methods, documentation and platform compatibility.
WooCommerce integration should update the order correctly
An ecommerce payment flow is not complete when the payment page opens. The store also needs accurate order creation, payment confirmation, failure handling and post-payment messaging.
For broader store implementation, see WooCommerce Development Services and Ecommerce Website Development Services.
Webhooks can be more reliable than browser redirects alone
A customer may pay successfully and then close the browser before returning to the website. Where the provider supports it, server-to-server notifications can help the application verify payment status independently of that return journey.
Do not expose secret credentials in browser code
Private API keys and other server-side credentials should remain on the server or within the secure configuration method recommended by the payment provider. Public checkout keys and secret keys have different roles and should not be treated as interchangeable.
Checkout UX still matters after the integration works
Users should understand the amount, item or service, next step and payment outcome. Error messages should be clear enough to help the customer retry or choose another option without creating duplicate orders.
Payment integration can be part of a larger web application
Custom portals, booking systems, subscription products and business applications may need payment logic tied to accounts, invoices, bookings or service status. In those cases the payment gateway is one integration within the larger application architecture.
For that scope, see Web Application Development Services.

Our integration process
Map the payment flow before adding live credentials.
01 · Review
Understand the platform and gateway
We identify the website stack, checkout flow, provider account status and the supported integration methods available.
02 · Plan
Define transaction states
Success, failure, cancellation, pending status and order updates are mapped before implementation begins.
03 · Configure
Connect the approved gateway
Supported plugins, apps or API endpoints are configured using test credentials where available.
04 · Integrate
Connect checkout and website logic
Payment creation, return routes, callbacks or webhooks are linked to the website’s order or application workflow.
05 · Test
Validate the important outcomes
Representative successful, failed and cancelled transactions are reviewed along with status updates and customer messaging.
06 · Launch
Move to live mode carefully
Live credentials are configured after merchant approval and final checks, followed by a controlled real-payment verification where appropriate.
Where payment integrations are used
The transaction flow should match the business model.
Ecommerce stores
Product checkout, taxes, shipping, coupons and order status need to remain consistent with the payment result.
Service websites
Collect approved online payments for consultations, appointments, project deposits or defined services where the provider permits the use case.
Booking platforms
Connect payment with booking confirmation, availability and cancellation rules when supported by the booking system.
Digital products
Use payment confirmation to control access or delivery workflows where the ecommerce or application platform supports it.
Custom portals
Tie payments to customer accounts, invoices, service requests or transaction records in a custom business application.
Subscription workflows
Where the provider and platform support recurring billing, integrate subscription creation and relevant lifecycle events into the application.
Building the whole commerce journey?
Payment integration works best when checkout, product structure and website performance are planned together.
If the project also needs a new store or application, the gateway can be included as part of the larger development scope instead of treated as an isolated technical task.
Frequently asked questions
Payment gateway integration questions
What is included in payment gateway integration?
Scope can include provider setup within the website, test credentials, checkout configuration, payment creation, return handling, webhooks or callbacks, order-status updates and final live-mode verification.
Can Vylino get my payment gateway account approved?
No. Merchant approval, KYC, settlement rules, supported business categories and account limits are controlled by the payment provider. Vylino can assist with the technical integration after suitable account access is available.
Can you integrate Razorpay with a website?
Where the merchant has an eligible Razorpay account and the website platform supports the required method, Vylino can configure a supported plugin or API-based integration and test the transaction flow.
Can you integrate Stripe payments?
Yes, where Stripe is available for the merchant and the selected website or application supports the required integration method.
Can you integrate a payment gateway with WooCommerce?
Yes. WooCommerce payment integration can include supported gateway plugins, checkout settings, test transactions, payment-state handling and post-payment order updates.
Can you integrate payments into a custom web application?
Yes, for supported providers with documented APIs. The scope depends on authentication, order creation, payment verification, callbacks, application logic and the provider’s technical requirements.
Is payment gateway integration secure?
Security depends on the gateway, implementation method, website configuration and how credentials and transaction verification are handled. Integrations should follow provider documentation and avoid exposing private credentials in client-side code.
How long does payment gateway integration take?
Technical integration time depends on the platform, provider, checkout complexity and testing requirements. Merchant account approval can take a separate amount of time controlled entirely by the payment provider.
