Description

This curriculum spans the technical and operational rigor of a multi-workshop integration program, addressing the same payment architecture, compliance, and transaction lifecycle challenges encountered in large-scale event platforms with distributed registration and on-site processing.

Module 1: Integration of Payment Gateways with Event Platforms

Selecting a PCI-compliant payment gateway that supports recurring billing for multi-day or installment-based event registrations.
Configuring API authentication (e.g., OAuth 2.0 or certificate-based) between the event management platform and the payment processor.
Mapping transaction response codes (e.g., 400 vs. 500 errors) to user-facing messages without exposing sensitive system details.
Handling asynchronous callback (webhook) failures from the payment gateway during high registration volume periods.
Testing fallback routing to secondary gateways during primary processor outages using real transaction simulations.
Validating 3D Secure 2.0 (3DS2) challenge flow integration to minimize cart abandonment while meeting SCA requirements.

Module 2: Compliance and Data Security in Payment Handling

Implementing tokenization to ensure credit card data never touches internal event registration servers.
Conducting annual PCI DSS SAQ-D assessments when managing partial card data flows within custom registration forms.
Designing data retention policies that align with both event refund timelines and PCI requirements for log deletion.
Enabling end-to-end encryption (E2EE) for card-present transactions at on-site event check-in kiosks.
Auditing third-party vendors (e.g., badge printers, mobile apps) for compliance with card data handling restrictions.
Responding to processor alerts about suspicious transaction patterns during flash registration windows.

Module 3: Currency, Pricing, and Dynamic Rate Management

Configuring dynamic currency conversion (DCC) options for international attendees while disclosing markup transparency.
Setting up automated foreign exchange rate refresh cycles to prevent pricing drift in multi-currency registration portals.
Managing early-bird, group, and last-minute pricing tiers with real-time synchronization across payment processors.
Handling partial refunds in original transaction currency when exchange rates have shifted post-payment.
Validating processor support for local payment methods (e.g., iDEAL, SEPA) in region-specific event promotions.
Reconciling settlement reports when multiple currencies are converted at batch-level by the acquiring bank.

Module 4: Refund, Cancellation, and Chargeback Workflows

Defining refund eligibility rules in code (e.g., time-based cutoffs) that align with processor chargeback timelines.
Automating partial refund calculations for events with tiered pricing and non-refundable deposits.
Logging audit trails for manual refund overrides to satisfy processor dispute evidence requirements.
Responding to representment requests by compiling registration timestamps, communication logs, and attendance records.
Classifying chargebacks by reason code (e.g., fraud vs. service not provided) to adjust event fulfillment processes.
Coordinating with legal teams when recurring chargebacks trigger reserve account holds by the acquirer.

Module 5: On-Site and Mobile Point-of-Sale Processing

Deploying EMV-compliant mobile card readers with offline mode capability for outdoor or low-connectivity venues.
Syncing offline transaction batches to the central system post-event while preventing duplicate processing.
Assigning role-based access to POS terminals for staff, limiting refund and void permissions by supervisor role.
Integrating on-site POS data with central CRM to update attendee purchase history in real time.
Calibrating settlement cut-off times to align with event session schedules and staff shift changes.
Managing device inventory and firmware updates across distributed event locations using MDM solutions.

Module 6: Financial Reconciliation and Settlement Reporting

Matching daily settlement files from the processor to internal registration records using transaction ID and batch number.
Identifying and investigating discrepancies caused by failed webhooks or incomplete authorization captures.
Allocating processor fees by event, ticket type, or payment method for accurate P&L reporting.
Automating reconciliation scripts to handle high-volume events with thousands of transactions.
Generating audit-ready reports that map gross sales, refunds, chargebacks, and net deposits.
Scheduling reconciliation jobs to run outside peak registration hours to avoid system contention.

Module 7: Fraud Detection and Transaction Monitoring

Configuring velocity rules to flag registrations with multiple cards from the same IP address.
Integrating with third-party fraud scoring services (e.g., Kount, Sift) using real-time API calls.
Establishing manual review queues for transactions flagged as high-risk without blocking legitimate registrations.
Updating fraud rules in response to new attack patterns observed during previous event cycles.
Monitoring for card testing behavior through small-dollar transaction spikes on registration portals.
Coordinating with the processor to whitelist known attendee geographies and reduce false declines.

Module 8: Scalability and High-Availability Payment Architecture

Load-testing payment APIs under simulated peak registration conditions (e.g., 10x normal traffic).
Implementing circuit breakers to prevent cascading failures when the payment gateway experiences latency.
Distributing registration traffic across multiple application instances with shared session state for payment continuity.
Designing retry logic for idempotent transaction requests without creating duplicate charges.
Using read replicas for reporting dashboards to avoid impacting transaction processing performance.
Planning failover procedures for registration systems when primary data centers are unreachable.
