Checkout and invoice integration
Connect supported provider flows to your website or software. Define how an order or invoice is created, how the customer continues and how the application establishes the final result.
Services
Make each payment step accountable.
Start with the provider, application and customer task involved.
Provider event handling
Review webhook verification, repeated events, delayed updates and processing failures. Record enough information to investigate a missing update without treating every notification as a new business action.
Refund and exception workflows
Define who can approve a refund or correction and how the authorized result appears in the application. Test supported scenarios in an isolated provider environment.
Reconciliation and reporting
Compare provider identifiers, amounts, currencies and internal records for the agreed scope. Flag mismatches for review instead of silently forcing records to agree.
Recurring and connected workflows
Review the integration around subscriptions, invoices or payouts where the provider supports it. For plan changes and access rules, see recurring billing services.
Discuss the first payment path. Live charges, refunds, payouts and account changes require separate explicit authorization.
