Overview
A payment gateway integration connects your website or online store with a supported payment provider so customers can move from checkout into an appropriate payment journey.
The integration may also need to handle transaction references, payment responses, status changes, order updates, booking confirmation and other post-payment activities.
Incodiv Tech develops payment integrations around the selected provider's supported APIs, SDKs, hosted checkout options, webhooks and technical requirements.
Payment methods, currencies, transaction capabilities, settlement, refunds and regional availability depend on the selected payment provider, merchant account, country and provider terms.

Business Challenges
Teams manually verify payments before progressing an order or booking.
The website journey and payment process are not properly connected.
Website records do not clearly reflect suitable transaction outcomes.
Payment callbacks or user actions need suitable handling to avoid unintended duplicate business actions.
Customers may not understand what to do when a payment is unsuccessful or pending.
Payment results may need to reach order, booking or management systems.
Payment Flow
Customer reaches the website payment step.
The selected provider handles payment activity.
The website receives suitable payment information.
Suitable transaction details are evaluated.
Relevant order or booking workflow continues.
Checkout
Payment integration is one part of the wider checkout experience. The website should also communicate the relevant order, booking or purchase information before the customer moves into the payment step.
Present suitable purchase information before payment.
Pass the appropriate amount into the payment flow.
Use suitable customer information where required by the flow.
Guide the user clearly after the payment attempt.
Payment Methods
Different gateways can support different payment methods depending on the merchant account, customer location, currency, country and provider configuration.
Where supported by the provider.
Provider-supported digital payment methods.
Where supported in the selected market.
Supported wallet options where available.
Market-specific methods where supported.
Provider-hosted checkout where appropriate.
Incodiv Tech does not determine which payment methods a provider approves for a merchant. Availability is controlled by the payment provider and merchant-account configuration.
Payment Status
Depending on the gateway, transactions may have different statuses. The website workflow should interpret supported provider states appropriately instead of assuming every request is immediately successful.
Continue the appropriate confirmed-payment workflow.
Handle transactions awaiting further provider status.
Provide a suitable failure path without confirming payment.
Handle suitable user or provider cancellation scenarios.
Webhooks
Some payment providers use webhooks to notify connected systems when relevant transaction events occur. This can help the website respond to payment changes that happen outside the customer's browser session.
Webhook implementation depends on the provider's available events, signing or verification method, retry behavior and technical documentation.
Business Workflow
A successful payment may need to update an order, confirm a booking, record a transaction reference, trigger communication or pass suitable information into another business system.
Connect payment status with suitable orders.
Update suitable reservation workflows.
Store relevant payment references and status.
Trigger appropriate customer communication.
Continue suitable post-payment processes.
Exchange suitable payment information.
Refunds
Some payment APIs provide refund capabilities that can potentially be integrated into an appropriate administrative or business workflow.
Locate the relevant transaction.
Submit a supported refund operation.
Receive the provider's result.
Update suitable business records.
Refund eligibility, timing, fees, partial refunds and settlement behavior are controlled by the payment provider and merchant agreement.
Testing
Where the provider offers a sandbox or test environment, the integration can be evaluated against relevant payment scenarios before production credentials are introduced.
Security
Payment integrations require careful consideration of how payment information is handled, which system receives sensitive data and what responsibilities belong to the merchant, website and payment provider.
Use supported provider-hosted experiences where appropriate for the project.
Handle suitable integration credentials according to the deployment architecture.
Apply provider-supported webhook verification mechanisms where available.
Limit unnecessary handling of sensitive payment information where practical.
Payment integration does not itself establish PCI DSS or other regulatory compliance. Compliance obligations depend on the merchant, provider, integration model, infrastructure, business processes and applicable requirements. Appropriate specialist guidance should be obtained where required.
Error Handling
Payment requests can fail for many reasons, including provider responses, network conditions, account restrictions, invalid requests or customer actions. The integration should account for relevant failure scenarios.
Identify the relevant response or error.
Log suitable technical information.
Show appropriate user-facing feedback.
Provide a suitable next step where possible.

The exact architecture depends on the payment provider, checkout model, website platform, business workflow and provider requirements.
