Some payment providers provide SDKs for websites, mobile applications, or other software environments.
An SDK may provide pre-built tools for implementing payment functionality without building every component from scratch.
AI PAY can help your technical team understand where an SDK fits into your payment architecture and what additional configuration or development may be required.

AI PAY can help you understand the available checkout options and determine how they can be implemented within your existing website or e-commerce system.

Webhook & Payment Status Integration
Know When a Payment Has Actually Been Completed
A customer returning to your website does not necessarily mean that a payment has been successfully completed.
Payment gateways may use **webhooks** or server-to-server notifications to send payment status updates to your system.
AI PAY can help you understand and implement payment status handling, including:
* Payment successful
* Payment pending
* Payment failed
* Payment cancelled
* Payment expired
* Refund initiated
* Refund completed
This allows your website or business system to update orders based on the payment information received from the payment provider.

Payment Verification
Verify Transactions Before Updating Orders
Payment verification is an important part of a reliable payment integration.
Your system may need to verify that a transaction is valid before:

* Confirming an order
* Providing access to digital products
* Sending products for fulfillment
* Updating inventory
* Triggering automated workflows
AI PAY can help you understand the payment verification process and the technical requirements provided by your selected payment gateway.

Order Synchronization
Connect Payments With Your Order System
Payment information and order information need to work together.
A properly designed integration can synchronize information between your website and payment gateway, such as:
**Customer → Order → Payment → Payment Status → Order Status**
Depending on your system, this can help automate processes such as:
* Updating order status
* Confirming successful payments
* Updating inventory
* Triggering fulfillment
* Sending customer notifications
* Recording transactions
* Processing refunds
---

Handle Refunds From Your Website or Business System
Refunds are another important part of payment integration.
Depending on the payment provider and API capabilities, refunds may be handled through:
* Payment gateway dashboard
* E-commerce platform
* Plugin
* API
* Custom application
AI PAY can help you understand how refund functionality can be connected to your existing order and payment workflow.

Payment Integration Testing
Test Before You Accept Real Payments
Before launching a payment gateway, the integration should be tested carefully.

* Payment status updates
* Webhook notifications
* Order synchronization
* Refund testing
* Error handling
* Checkout testing
* Mobile checkout testing
The goal is to identify integration problems before your customers encounter them.
