Overview

WEBSITE PAYMENT EXPERIENCES

Connect the point of purchase with the payment process.

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.

02

Disconnected Checkout

The website journey and payment process are not properly connected.

03

Unclear Payment Status

Website records do not clearly reflect suitable transaction outcomes.

04

Duplicate Processing Risk

Payment callbacks or user actions need suitable handling to avoid unintended duplicate business actions.

05

Poor Failure Experience

Customers may not understand what to do when a payment is unsuccessful or pending.

06

Disconnected Business Systems

Payment results may need to reach order, booking or management systems.

04

Payment Flow

FROM CHECKOUT TO CONFIRMATION

Design the payment journey as a connected process.

01

Checkout

Customer reaches the website payment step.

02

Payment

The selected provider handles payment activity.

03

Response

The website receives suitable payment information.

04

Validate

Suitable transaction details are evaluated.

05

Continue

Relevant order or booking workflow continues.

05

Checkout

PAYMENT AT THE RIGHT POINT

Connect payment to a clear checkout journey.

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.

01

Order Summary

Present suitable purchase information before payment.

02

Amount

Pass the appropriate amount into the payment flow.

03

Customer Information

Use suitable customer information where required by the flow.

04

Next Step

Guide the user clearly after the payment attempt.

06

Payment Methods

PROVIDER-SUPPORTED OPTIONS

Payment methods depend on the provider and market.

Different gateways can support different payment methods depending on the merchant account, customer location, currency, country and provider configuration.

Cards

Where supported by the provider.

Digital Payments

Provider-supported digital payment methods.

Bank-Based Payments

Where supported in the selected market.

Wallets

Supported wallet options where available.

Regional Methods

Market-specific methods where supported.

Hosted Payment

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.

07

Payment Status

TRANSACTION OUTCOMES

A payment attempt can have more than one outcome.

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.

01

Successful

Continue the appropriate confirmed-payment workflow.

02

Pending

Handle transactions awaiting further provider status.

03

Failed

Provide a suitable failure path without confirming payment.

04

Cancelled

Handle suitable user or provider cancellation scenarios.

08

Webhooks

PAYMENT EVENT NOTIFICATIONS

Use supported payment events to update the website workflow.

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.

01 Payment Event
02 Webhook
03 Validate
04 Update

Webhook implementation depends on the provider's available events, signing or verification method, retry behavior and technical documentation.

09

Business Workflow

AFTER THE PAYMENT

Connect payment status with the relevant business record.

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.

01

Orders

Connect payment status with suitable orders.

02

Bookings

Update suitable reservation workflows.

03

Transactions

Store relevant payment references and status.

04

Notifications

Trigger appropriate customer communication.

05

Fulfilment

Continue suitable post-payment processes.

06

Business Systems

10

Refunds

POST-PAYMENT OPERATIONS

Support suitable refund workflows where the provider allows it.

Some payment APIs provide refund capabilities that can potentially be integrated into an appropriate administrative or business workflow.

01 Identify

Locate the relevant transaction.

02 Request

Submit a supported refund operation.

03 Response

Receive the provider's result.

04 Update

Update suitable business records.

Refund eligibility, timing, fees, partial refunds and settlement behavior are controlled by the payment provider and merchant agreement.

11

Testing

BEFORE LIVE PAYMENTS

Validate supported scenarios before production use.

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 DATA CONSIDERATIONS

Choose an integration model appropriate for payment data.

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.

01

Provider-Hosted Flows

Use supported provider-hosted experiences where appropriate for the project.

02

Credentials

Handle suitable integration credentials according to the deployment architecture.

03

Webhook Verification

Apply provider-supported webhook verification mechanisms where available.

04

Data Scope

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.

13

Error Handling

PAYMENT FAILURES & EXCEPTIONS

Plan for more than the successful payment path.

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.

01 Detect

Identify the relevant response or error.

02 Record

Log suitable technical information.

03 Inform

Show appropriate user-facing feedback.

04 Recover

Provide a suitable next step where possible.

14

Architecture

CONNECTED PAYMENT ARCHITECTURE

Keep payment processing connected to the right systems.

01 Customer
02 Website
03 Payment Provider
04 Business Record

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

FAQ

COMMON QUESTIONS

Payment gateway integration questions.

What is payment gateway integration? +

Payment gateway integration connects a website or online store with a supported payment provider so customers can move through an appropriate online payment process.

Can you integrate payments into an e-commerce website? +

Yes, where the selected e-commerce platform, payment provider, merchant account and required payment flow support the integration.

Can you integrate payment gateways into a custom website? +

Yes. A custom integration may be possible when the provider offers suitable APIs, SDKs, hosted checkout or other supported integration methods.

Can payments be connected with bookings? +

Yes, suitable booking workflows can potentially use payment status to determine what happens next, depending on the business requirements and provider capabilities.

Can payment status update automatically? +

Where the provider offers suitable webhooks or status APIs, transaction information can potentially be used to update relevant website records automatically.

Can you integrate refunds? +

Refund workflows may be integrated where the payment provider exposes suitable refund APIs and the merchant account is permitted to use them.

Do you test payment integrations before going live? +

Where the payment provider offers an appropriate sandbox or test environment, relevant supported payment and error scenarios can be tested before production configuration.

Does payment integration make my website PCI compliant? +

No. Compliance obligations depend on the merchant, provider, payment architecture, infrastructure and applicable requirements. Integration work should not be treated as an independent certification of compliance.

Can every payment gateway work in every country? +

No. Payment providers have different regional, currency, merchant, business-type and account requirements. Provider suitability should be confirmed before implementation.

Can you improve our existing payment integration? +

We can review suitable existing integrations where the website source code, payment-provider documentation, relevant access and technical environment are available for assessment.
